# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5        - Removed code duplication in SFZ file loading code.
6        - Added support for sfz extension opcode 'script' which may be used to
7          load real-time instrument script file (NKSP script language).
8        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9        - Fixed unintended volume fade-in of voices under certain conditions.
10    
11      * Gigasampler/GigaStudio format engine:
12        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13          cutoff settings.
14    
15      * general changes:
16        - fixed printf type errors (mostly in debug messages)
17        - use unique_ptr instead of auto_ptr when building with C++11
18        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19          allowing to sort data efficiently in real-time safe manner.
20        - RTList class: added methods for moving/inserting elements to arbitrary
21          position within a list.
22        - RTList class: added method fromPtr() for creating an Iterator object from
23          a raw element pointer.
24        - Attempt to partly fix resetting engine channels vs. resetting engine, an
25          overall cleanup of the Reset*(), ConnectAudioDevice(),
26          DisconnectAudioDevice() API methods would still be desirable though,
27          because the current situation is still inconsistent and error prone.
28        - Active voices are now internally grouped to "Note" objects, instead of
29          being directly assigned to a keyboard key. This allows more fine graded
30          processing of voices, which is i.e. required for certain instrument
31          script features.
32        - Fix: Release trigger voices were not spawned on sustain pedal up
33          (CC #64) events.
34        - Fix: Release trigger voices can now also distinguish correctly between
35          note-off and sustain pedal up events.
36        - All engines: Increased ramp speed of volume smoother and pan smoother
37          (while slow rate of crossfade smoother is preserved) to allow quick
38          volume and pan changes by instrument scripts for instance.
39        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40          properly and thus were ignored for certain uses.
41        - Added new C++ API method
42          VirtualMidiDevice::SendChannelPressureToSampler().
43        - windows, 32-bit: fixed potential crashes by making sure the stack in
44          sub threads is 16-byte aligned
45        - fixed numerous compiler warnings
46    
47      * packaging changes:
48        - removed unnecessary dependency to libuuid
49          (originated by libgig's usage of it)
50        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
51          auto detect whether it (sh/c)ould output its messages in color.
52    
53      * Real-time instrument scripts:
54        - Implemented scheduler for delayed MIDI events and for suspended scripts.
55        - Built-in script function "wait()": implemented support for function's
56          "duration-us" argument, thus scripts using this function are now
57          correctly resumed after the requested amount of microseconds.
58        - Built-in script function "play_note()": implemented support for
59          function's "duration-us" argument, thus notes triggered with this
60          argument are now correctly released after the requested amount of
61          microseconds.
62        - Fix: script events were not cleared when engine channel was reset,
63          potentially causing undefined behavior.
64        - Fixed crash which happened when trying to reference an undeclared
65          variable.
66        - Built-in script function "play_note()": Added support for passing
67          special value -1 for "duration-us" argument, which will cause the
68          triggered note to be released once the original note was released.
69        - Instrument script classes now exported with the liblinuxsampler C++ API.
70        - Added new API method ScriptVM::syntaxHighlighting() which provides
71          a convenient syntax highlighting backend for external instrument
72          script editor applications.
73        - Added new C++ API class "ScriptVMFactory".
74        - Extended parser issues to provide not only first line and first
75          column, but also last line and last column of issue (thus marking
76          the precise span of the issue within the source code).
77        - Reload script automatically after being modified by an instrument
78          editor.
79        - NKSP language grammar correction: allow empty event handler bodies
80          like "on note end on".
81        - Implemented built-in script function "change_vol()".
82        - Implemented built-in script function "change_tune()".
83        - Implemented built-in script function "change_pan()".
84        - Implemented built-in script function "change_cutoff()".
85        - Implemented built-in script function "change_reso()".
86        - Implemented built-in script function "event_status()".
87        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
88          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
89          "event_status()" function.
90        - NKSP language: Added support for bitwise operators ".or.", ".and."
91          and ".not.".
92        - NKSP language scanner: Fixed IDs matching to require at least one
93          character (i.e. when matching function names or variable names).
94        - NKSP language scanner: disabled unusued rules.
95        - Fixed behavior of play_note() and note_off() functions which must
96          be distinguished engine internally from "real" MIDI note on/off
97          events in order to avoid misbehaviors like hanging notes.
98        - Implemented built-in script variable "$KSP_TIMER".
99        - Implemented built-in script variable "$NKSP_REAL_TIMER".
100        - Implemented built-in script variable "$NKSP_PERF_TIMER".
101        - Implemented built-in script variable "$ENGINE_UPTIME".
102        - Implemented built-in script function "inc()".
103        - Implemented built-in script function "dec()".
104        - NKSP language fix: division expressions were evaluated too often.
105        - NKSP language fix: string concatenation operator was right
106          associative instead of left (to right).
107        - NKSP language correction: allow empty statements in entire language
108          (i.e. "if end if").
109        - Implemented built-in script function "stop_wait()".
110        - Implemented built-in script variable "$NI_CALLBACK_ID".
111        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
112        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
113        - Added support for read-only built-in variables (respectively
114          handled by the script parser).
115        - Added built-in script constant "$NI_CB_TYPE_INIT".
116        - Added built-in script constant "$NI_CB_TYPE_NOTE".
117        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
118        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
119        - NKSP Language: Added support for user defined script functions.
120        - Implemented built-in script function "change_attack()".
121        - Implemented built-in script function "change_decay()".
122        - Implemented built-in script function "change_release()".
123        - Fixed all change_*() built-in script functions to apply their
124          synthesis parameter changes immediately in case the respective note
125          was triggered at the same time, instead of scheduling the parameter
126          change, especially because it would cause some parameter types's
127          changes either to be ramped (i.e. change_vol()) or other types even
128          to have not effect at all (i.e. change_attack()).
129        - Implemented built-in script function "sh_left()".
130        - Implemented built-in script function "sh_right()".
131        - Implemented built-in script function "min()".
132        - Implemented built-in script function "max()".
133        - NKSP Fix: "init" event handler was not always executed when a script
134          was loaded.
135        - NKSP built-in wait() script function: abort script execution if
136          a negative or zero wait time was passed as argument (since this is
137          a common indication of a bug either of the script or even of the
138          engine, which could lead to RT instability or even worse).
139        - ScriptVM: Implemented automatic suspension of RT safety
140          threatening scripts.
141        - Provide more user friendly error messages on syntax errors.
142        - Fixed NKSP parser warning "Not a statement" when assigning an
143          initializer list to an array variable.
144        - Implemented built-in script array variable "%ALL_EVENTS".
145        - Implemented built-in script function "in_range()".
146        - Implemented built-in script function "change_amp_lfo_depth()".
147        - Implemented built-in script function "change_amp_lfo_freq()".
148        - Implemented built-in script function "change_pitch_lfo_depth()".
149        - Implemented built-in script function "change_pitch_lfo_freq()".
150        - Implemented built-in script function "change_vol_time()".
151        - Implemented built-in script function "change_tune_time()".
152        - Implemented built-in script function "fade_in()".
153        - Implemented built-in script function "fade_out()".
154        - Fixed acceptance of wrong data type of parameters passed to built-in
155          script functions "change_vol()", "change_tune()", "change_pan()",
156          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
157          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
158          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
159    
160      * Instruments DB:
161        - Fixed memory access bug of general DB access code which lead to
162          undefined behavior.
163        - Cleanup of instruments DB file creation and opening code.
164        - The instrument DB path of linuxsampler's --create-instruments-db argument
165          is now optional, if it is missing, then a default location is used.
166        - Added support for scanning SFZ (.sfz) files.
167        - Added support for scanning Sound Font (.sf2) files.
168        - Fixed undefined DB transaction behavior.
169

174        - Mac OS X: support the new dir for Core Audio SDK
175        - Mac OS X: fixed building outside source directory
176        - made sure all source files for hostplugins are included when
177          doing "make dist"
178        - removed empty directories left from the cvs to svn migration
179        - fixed compilation with gcc 4.6.1
180        - another "make dist" fix, for the LV2 plugin
181        - made --enable-pthread-testcancel default on Mac OS X
182        - minor Makefile fix for building lscpparser when build and source
183          directories are separate
184        - Mac OS X: made it possible to specify plugin installation dir to
185          configure
186        - Mac OS X: Makefile fix for the install-strip target
187        - fixed compilation with gcc 4.7
188        - fixed configure script error with old autoconf versions
189        - lsatomic.h: use gcc provided atomic functions if building with
190          gcc 4.7 and C++11
191        - modernized configure script
192        - fixed linkage error when building with
193          LDFLAGS="-Wl,--no-undefined" (#190)

202          on the process's main thread
203        - fixed build error on newer MinGW
204        - support building with older jack versions
205        - support building with spaces in vst sdk path
206        - enabled automake 'subdir-objects' option and moved external
207          source references (vst, au, asio) from makefiles to cpp files,
208          in order to get rid of warnings from automake 1.14
209    
210      * general changes:
211        - Refactoring: moved the independent code from
212          the Gigasampler format engine to base classes
213        - command line option '--profile' is currently disabled, since the
214          respective profiling code is currently broken
215        - Introduced support for optional environment variable
216          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
217          where the sampler shall look for instrument editor plugins
218          (patch by Luis Garrido, slightly modified).
219        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
220        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
221        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
222          note (in this implementation of the sampler its simply hard routed to
223          the 1st effect send of the sampler channel, no matter what the actual
224          effect type is)
225        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
226          note (in this implementation of the sampler its simply hard routed to
227          the 2nd effect send of the sampler channel, no matter what the actual
228          effect type is)
229        - implemented support for internal LADSPA effects
230        - raised limit of program change queue from 100 to 512
231          (as suggested by Alex Stone)
232        - implemented sine LFO, pulse LFO and saw LFO
233        - experimental support for per voice equalization
234        - added command line option --exec-after-init
235        - Introduced new C++ API method:
236          EngineChannel::InstrumentFileName(int index)
237          allowing to retrieve the whole list of files used for the loaded
238          instrument on an engine channel (a.k.a. part). Some GigaStudio
239          instruments for example are splitted over several files like
240          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
241        - Added new C++ API method Sampler::GetGlobalMaxVoices().
242        - Added new C++ API method Sampler::GetGlobalMaxStreams().
243        - Added new C++ API method Sampler::SetGlobalMaxVoices().
244        - Added new C++ API method Sampler::SetGlobalMaxStreams().
245        - Various "const" and "restrict" optimizations.
246        - all engines: add pan CC value to instrument pan parameter before
247          applying panning, instead of using two separate pan functions in
248          series (#182)
249        - added a lock guard class for exception safe mutex handling and
250          used it everywhere appropriate
251        - Immediately apply scale tuning changes to active voices.
252        - Exposed scale tuning to C++ API (along to the already existing standard
253          SysEx way).
254        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
255          and broken for ppc64. (Seq_cst loads and stores are actually not
256          used in LS, so the bug wasn't noticable.)
257        - lsatomic.h: added ARMv7 support
258        - Added support for multiple MIDI input ports per sampler channel (and
259          added various new C++ methods for this new feature / design change, old
260          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
261          as deprecated but are still there and should provide full behavior
262          backward compatibility).
263        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
264          unsafe and caused compilation error with clang 2.x).
265        - Bugfix: only process the latest MIDI program change event.
266        - Introducing the LSCP shell, which provides convenient control of the
267          sampler from the command line by providing LSCP aware features.
268        - VirtualMidiDevice: Added support for program change.
269        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
270        - VirtualMidiDevice: Added support for pitch bend.
271        - Aftertouch: extended API to explicitly handle channel pressure and
272          polyphonic key pressure events (so far polyphonic pressure was not
273          supported at all, and channel pressure was rerouted as CC128 but not
274          used so far).
275        - Added initial support for real-time instrument scripts. The script VM
276          code is shared by all sampler engine implemementations, however only the
277          gig file format currently provides support for storing instrument scripts
278          (as LinuxSampler extension to the original GigaStudio 4 format).
279    
280      * Gigasampler format engine:
281        - implemented the "round robin keyboard" dimension
282        - fixed round robin and random dimensions for cases when number of
283          dimension zones is not a power of two
284        - made round robin use a counter for each region instead of each
285          key
286        - bugfix: pitch LFO controller "internal+aftertouch" was broken
287        - bugfix: filter keyboard tracking was broken
288        - filter performance fix (an unnecessary copy was made of the
289          filter parameters in each sub fragment)
290        - handle special case when pan parameter in gig file has max or
291          min value
292        - Exclusive Groups: don't ever stop voices of the same note,
293          doesn't sound naturally with a drumkit
294        - fixed EG1 modulation when attack or release is zero
295        - Fixed support for 'aftertouch' attenuation controller.
296        - Fixed crash that happened with velocity split sounds under certain
297          conditions (see also previous commit on libgig).
298        - fixed behaviour of filter LFO
299    
300      * SFZ format engine:
301        - Initial implementation (not usable yet)
302        - added support for v2 multiple stage envelope generators
303        - added a fine-tuned v1 envelope generator instead of using the
304          one from the gig engine
305        - fixed memory leak and memory handling errors
306        - added support for trigger=first, trigger=legato and sw_previous
307        - allow non-numerical key values ("C#4" for example)
308        - "key" opcode now sets pitch_keycenter too
309        - fixed error when unloading instrument with same sample used by
310          multiple regions
311        - added some opcode aliases, like loopmode for loop_mode, to be
312          more compatible
313        - added support for trigger=release and rt_decay
314        - added support for off_mode=normal
315        - added support for random, seq_position, seq_length and volume
316        - added v1 LFO opcodes to parser (no support in engine yet)
317        - added support for amp_veltrack and amp_velcurve_N
318        - fine-tuned the default velocity curve
319        - added support for transpose
320        - fixed crash when using sw_down/up
321        - improved logic for sw_lokey/hikey/up/down/last
322        - added more v1 aliases to parser
323        - reduced memory usage for sfz data
324        - RT-safeness: avoid malloc in audio thread
325        - fixed a bug that could cause voice stealing to fail
326        - optimized sample lookup
327        - improved support for exclusive groups (group, off_by and
328          off_mode)
329        - added support for controller triggered regions (on_locc/on_hicc)
330        - added support for loop_mode=one_shot
331        - fixed playback of 16 bit wav files on big endian CPUs
332        - added support for Ogg Vorbis sample files
333        - use loop markers from sample file if loop_start and loop_end are
334          not set in sfz file
335        - implemeted filters. Filter types: lowpass, bandpass, bandreject
336          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
337          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
338          cutoff_cc, cutoff_chanaft.
339        - bugfix: zero ampeg_sustain didn't work
340        - added support for velocity effect on amplifier envelope time
341          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
342          ampeg_vel2release)
343        - added support for EG hold (ampeg_hold)
344        - added support for sample offset (offset)
345        - use the newly introduced signal units model
346        - implemented opcodes lfoN_delay,

479          incorrectly set to two. This caused silence in Cubase 5.
480        - save engine type (gig, sfz or sf2) in plugin state
481        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
482          64 bit Windows

537        - MME bugfix: driver wasn't closed properly
538        - CoreMIDI: automatically connect to all input sources by default (driver
539          parameter "AUTO_BIND").

693        - sfz/sf2 engine: fixed crash when using small audio fragment size
694        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
695        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
696          introduced in previous fix)
697        - fixed crash when a channel received a program change while
698          playing a note in a key group
699        - fixed erroneous error message piping in VoiceBase.h
700          (labelled "Disk stream not available in time")
701        - Update effects on sample rate & period size changes (to avoid
702          crashes and noise on such transitions).
703        - ignore missing LADSPA paths without ignoring valid LADSPA paths
704          (fixes #208)
705        - Fixed bug in LSCP grammar definition which caused a statement like
706          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
707          practically irrelevant, however it caused problems with the new LSCP
708          shell's auto completion feature).
709        - Fixed MIDI program change messages being ignored if quickly executed
710          after each other (fixes #231).
711    
712    Version 1.0.0 (31 July 2009)
713    
714      * packaging changes:
715        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
716          causing e.g. the libgig test to fail when
717          "./configure --disable-jack-driver" was used
718          (patch by Alexis Ballier)
719        - fixed compilation with gcc 4.3
720        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
721        - fixed configure so it detects x86_64 (#107)
722        - fixes for building with newer MinGW versions
723        - fix for building with bison 2.4 (#111)
724        - fixed building with libgig installed in a non-standard directory
725        - minor fix in configure for mmsystem.h detection on MinGW
726        - Windows: look for editor plugins and Fantasia using base
727          directory of liblinuxsampler dll (look in the same directory and one
728          directory above)
729        - configure script fix: removed unconditional use of SSE
730        - fixed building with sqlite installed in a non-standard directory
731        - when cross-compiling, don't try to create instruments.db
732        - fix for new mingw-w64 version, which has usleep
733    
734      * general changes:
735        - bugfix: on some POSIX systems instrument editor plugins refused to
736          load as we used a non-portable Linux specific struct field
737          (fixes bug #70, patch by Ronald Baljeu)
738        - fixed endless loop which occured when loading an instrument editor
739          plugin DLL on Windows systems failed
740        - fixed memory leaks that occurred when liblinuxsampler was unloaded
741        - optimized the SynchronizedConfig class so it doesn't wait
742          unnecessarily long after an update
743        - added support for notifying instrument editors on note-on / note-off
744          events (e.g. to highlight the pressed keys on the virtual keyboard
745          of gigedit)
746        - added support for triggering notes by instrument editors (see above)
747        - be verbose on DLL load errors (on Linux)
748        - fixed di-harmonic triangle LFO implementation (this LFO implementation
749          is only used by very few systems, most pick the int math
750          implementation, which is usually faster)
751        - fixes for audio drivers with varying buffer sizes
752        - experimental support for running LinuxSampler as a DSSI, LV2 and
753          VST plugin
754        - notification events for stream/voice count statistics are now sent
755          only when there are actual changes
756        - added memory ordering constraints to improve stability on
757          multi-core and multi-cpu systems
758        - maximum voices and disk streams can now be altered at runtime
759        - fixed CPU feature detection on x86_64 (maybe fixes #108)
760        - automatic stacktrace mechanism is now turned off by default and can
761          be switched on by command line option "--stacktrace" (the automatic
762          stacktrace mechanism seems to be broken on most systems at the moment)
763        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
764          a pointer to the launched InstrumentEditor object
765        - added optional 3rd party user data parameter for following
766          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
767          InstrumentEditor::Launch(),
768          InstrumentManager::LaunchInstrumentEditor()
769        - theoretical fix: made SynchronizedConfig follow C++0x memory
770          model more strictly
771        - fixes for using large audio device buffers
772        - Windows: add the installation directory to the DLL search path
773          when loading an editor plugin (solves problems with VST and
774          gigedit on systems with other GTK versions installed)
775        - updated linuxsampler man page
776    
777      * audio driver:
778        - removed the nonsense audio channel constraint (which was hard coded to
779          max. 100 audio channels) for most audio drivers
780        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
781          opposed to the LSCP specs
782        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
783          reflected the wrong value
784        - fixed a memory management bug in ASIO driver
785        - Makefile fix: JACK_CFLAGS wasn't used
786        - JACK: use jack_client_open instead of the deprecated
787          jack_client_new
788        - added (experimental) CoreAudio driver
789        - applied old fixes to the ASIO driver that were included in the
790          previous binary release but accidentally never committed to CVS
791          (fixes #117)
792        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
793          win64)
794        - VST: added support for sample rate and buffer size changes
795        - VST: close editor (Fantasia) when the VST is removed
796        - VST: avoid opening Fantasia more than once for each VST instance
797        - VST: export main function as "main" on Linux too (fix for
798          energyXT)
799        - VST: changed number of output channels from one stereo to 16
800          stereo
801        - added channel routing, fxsends and midi maps to the settings
802          stored in the plugin state
803        - performance optimization of AudioChannel::MixTo() and
804          AudioChannel::CopyTo() methods using GCC vector exensions
805          (if available)
806        - ASIO fixes: avoid initializing the device twice, avoid throwing
807          exception when getting parameters from a disconnected device
808    
809      * MIDI driver:
810        - added JACK MIDI driver
811        - dispatch bank select as ordinary CC as well, the user might seriously
812          want to (mis)use it for some purpose ("fixed" in all current MIDI
813          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
814        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
815          CoreMidi or AU
816        - fixed mingw-w64 compilation error in MME driver
817        - made program change handling in MIDI thread real-time safe by
818          moving the logic to a non-RT thread
819        - fixed minor memory leak in ALSA driver
820    
821      * instruments database:
822        - avoid time consuming samples scanning when adding instruments
823          to the instruments database
824        - added support for handling lost files in the instruments database
825        - Implemented option for adding instruments in separate directories
826          in the instruments database
827          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
828        - work-around for missing fnmatch function on Windows to make
829          instrument database compilable
830        - added instrument database support on Windows
831          works with both standalone mode and VST plugin.
832          the instruments DB file is located in
833          %USERPROFILE%\.linuxsampler\instruments.db which allows different
834          databases for each windows user
835          if no DB is present it automatically creates the .linuxsampler subdir
836          and then creates an empty DB
837        - fixed recursive import, which was broken on Windows
838    
839      * Gigasampler format engine:
840        - fixed a memory leak that could happen when a channel was deleted
841          while notes were playing
842        - made it possible to load an instrument even if the audio thread
843          isn't running
844        - added partial support for the "Controller Triggered" MIDI rule,
845          enough for piano gigs with pedal noise samples
846        - minor fix: only mark FX sends as being modified if really the
847          respective FX send MIDI controller was used
848        - added support for GM global device volume SysEx message
849          (can be selected at compile time to either apply globally to the
850          whole sampler [default] or only to the sampler channels that are
851          connected to the respective MIDI input port the SysEx message arrived
852          on)
853        - bugfix: notes triggered at position 0 in the audio buffer were
854          sometimes wrongly killed in the same buffer, causing no sound to
855          be played
856        - added support for chromatic / drumkit mode Roland GS Sysex message
857          which is usally used to switch a part between chromatic sounds and
858          drumkit sounds (as opposed to their common default setting of MIDI
859          part 10 being a drumkit part and all other ones chromatic parts), in
860          LS however one can switch between the first 16 MIDI instrument maps
861          defined for the sampler
862        - made it possible to create multiple sample channels even if the
863          audio thread isn't running
864        - fixed crash when removing channel with active voices (#116)
865        - bugfix: on sample reference changes (instrument editor), only
866          un-cache the respective sample if it's really not used by any
867          sampler engine anymore
868        - re-cache samples in case they were changed by an instrument editor,
869          e.g. when a sample was added while playing (#82)
870        - fixed hanging notes which occured when note-off event had the exact
871          same time stamp as the voice's note-on event and occured both in the
872          same audio fragment cycle (fixes bug #112)
873        - added support for the "fine tune" and "pitch bend range"
874          instrument-level gig parameters
875        - fixed minor artifacts in pitch bend handling
876        - added support for GS Reset SysEx message
877        - allow gig files to use unlimited downward pitch shifting
878        - added a limit check for upward pitch shifting
879        - bugfix: sometimes, when playing a note twice fast, the second
880          note was silent
881        - fixed crash happening when a pitch bend event arrived at the
882          same time a new instrument was loading
883    
884      * LSCP server:
885        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
886          react on MIDI data arriving on certain sampler channels (so far only
887          Note-On and Note-Off events are sent via this LSCP event)
888        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
889          react on MIDI data arriving on certain MIDI input devices (so far only
890          Note-On and Note-Off events are sent via this LSCP event)
891        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
892          SET DB_INSTRUMENT FILE_PATH
893        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
894          frontends to send MIDI messages to specific sampler channel
895        - added two additional fields to GET FILE INSTRUMENT INFO command -
896          KEY_BINDINGS and KEYSWITCH_BINDINGS
897        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
898          was incorrect
899        - Optimized the retrieval of the MIDI instrument mappings
900        - added new LSCP command "SET VOICES" to globally alter the maximum
901          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
902          be triggered respectively
903        - added new LSCP command "SET STREAMS" to globally alter the maximum
904          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
905          which will be triggered respectively
906        - bugfix: retry if "select" returns EINTR (this fixes a crash when
907          a gigedit file dialog is opened)
908        - close all connections when LSCPServer is deleted
909        - hard close of all sockets on exit
910        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
911          driver
912    
913      * Bug fixes:
914        - fixed a crash which occurs when removing a sampler channel waiting
915          to start instrument loading after another channel
916        - fixed a crash which occurs when removing a sampler channel with
917          instrument loading in progress (bug #113)
918        - fixed termination caused by uncaught exception when adding MIDI
919          instrument with PERSISTENT load mode
920        - fixed possible iterator invalidations when resetting the sampler
921        - fixed memory leaks when issuing the following LSCP commands:
922          GET AUDIO_OUTPUT_DRIVER INFO
923          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
924          GET MIDI_INPUT_DRIVER INFO
925          GET MIDI_INPUT_DRIVER_PARAMETER INFO
926        - fixed possible compilation error when sqlite is not present
927        - fixed orphaned pointers when setting maximum voices limit (bug #118)
928        - fixed crash when changing the audio output device of a sampler
929          channel with loaded instrument and start playing notes
930        - fixed endless loop in Engine::SuspendAll() (bug #120)
931        - fixed a low-level atomic load function that was broken on 64-bit
932          PowerPC, which probably could cause crashes on that platform
933        - fixed a memory management error which could cause a crash when a
934          plugin was unloaded
935        - bugfix: two private structs had the same name, which could cause
936          problems if the linker chose the wrong constructor
937        - fixed low-level ConditionServer usage bug that caused lockups on
938          Windows
939    
940    
941    Version 0.5.1 (6 December 2007)
942    
943      * packaging changes:
944        - added autoconf checks for pthread library
945        - added autoconf check for pthread bug found on certain NPTL-enabled
946          glibc versions (see Gentoo bug report #194076)
947        - added autoconf checks for MS Windows
948    
949      * general changes:
950        - bugfix: the thread used by an editor plugin didn't die when the
951          editor closed
952        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
953          out all the space. operator--() did not apply size_mask after
954          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
955          order to avoid problems with the _NonVolatileReader functions.
956        - bugfix: Stream.h: added a missing divide by BytesPerSample in
957          GetWriteSpace(). Since this function is currently only used in
958          the stream's qsort() compare function, it didn't trigger any
959          bugs.
960        - Resampler.h, Synthesizer.h: cubic interpolation now works in
961          24bit mode too. Faster method to read 24bit words on little
962          endian machines (x86): replaced 3 byte reads + shifts with a 1
963          unaligned 32bit read and shift
964        - experimental support for MS Windows (MIDI input via MME, AUDIO
965          output via ASIO)
966        - made handling of SIGINT signal (Ctrl-C) a bit more robust
967        - support for monitoring the total number of active disk streams
968          (new LSCP commands: GET TOTAL_STREAM_COUNT,
969          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
970    
971      * AUDIO driver:
972        - added Windows ASIO low latency audio driver
973    
974      * MIDI driver:
975        - added MME Windows MIDI driver
976    
977      * LSCP server:
978        - added support for Windows style path / filenames, however with
979          forward slash path separators instead of backslash
980          (i.e. "C:/foo/bar.gig")
981        - allow naughty liblscp to send non-string device parameters within
982          apostrophes as well
983        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
984          "LIST FILE INSTRUMENTS <file>" and
985          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
986          about an arbitrary instrument file on the system where the sampler is
987          running on
988    
989    Version 0.5.0 (15 October 2007)
990    
991      * packaging changes:
992        - config.h is not going to be installed along with liblinuxsampler's
993          API header files anymore
994        - only the API relevant header (and source) files will be exported to
995          the Doxygen API documentation (explicitly listed in Doxyfile.in)
996        - added completely new XCode project files for Mac OSX which is now
997          capable to execute our autoconf environment, thus no need anymore
998          to maintain the compile time configuration file (osx/version.h) for
999          OSX manually (patch by Toshi Nagata)
1000        - fixed buggy boolean --enable-foo / --disable-foo configure script
1001          parameters
1002        - global.h now only covers global definitions that are needed for the
1003          C++ API header files, all implementation internal global definitions
1004          are now in global_private.h
1005        - atomic.h is not exposed to the C++ API anymore
1006        - no need to include config.h anymore for using LS's API header files
1007        - fixed warnings in API doc generation
1008    
1009      * general changes:
1010        - replaced the old, confusing MIDI program change mechanism by a
1011          flexible MIDI instrument mapper which allows to map arbitrary
1012          (MIDI bank, MIDI program) pairs with arbitrary
1013          (engine type, instrument file, file index) triplets which will be
1014          loaded on the respective channel when such MIDI program change
1015          messages arrive, beside that, each entry allows to define a life-time
1016          strategy for the instrument, so the user can define whether the
1017          instrument should i.e. be permanently loaded (to be able to switch
1018          quickly among sounds) or i.e. loaded just on demand when the
1019          respective program change arrives (to safe RAM space), as well as a
1020          global volume factor for each entry, so the user can adjust the volume
1021          dynamic of his mapped instrument collection without having to modify
1022          the instrument files, also one can manage arbitrary amount of such
1023          MIDI instrument maps and assign each sampler channel individually
1024          a certain map, so that i.e. separation of normal instruments and
1025          drumkits is possible
1026        - new notification events for tracking changes to audio/MIDI devices,
1027          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1028        - sampler was limited to load max. 200 instruments in the background
1029          due to a constant size RingBuffer FIFO which is now replaced by a
1030          dynamic (unlimited) size std::list FIFO
1031        - added FX sends, these allow to route audio signals to arbitrary audio
1032          output channels for being processed by external effect processors
1033          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1034          controllers
1035        - global (sampler wide) volume can now be controlled at runtime
1036        - Implemented new, improved notification system
1037        - fixed compilation errors regarding OSX
1038          (patch by Toshi Nagata)
1039        - implemented instruments database
1040        - added support for escape sequences to the instruments database
1041        - added highly experimental support for on-the-fly instrument editing
1042          within the sampler's process (by using instrument editor plugins),
1043          you'll notice the new "Registered instrument editors:" message on
1044          startup, added a new LSCP command:
1045          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1046          to spawn a matching instrument editor for the instrument on the
1047          given sampler channel, the plugin path can be overridden at compile
1048          time with ./configure --enable-plugin-dir=/some/dir
1049        - added experimental code for synchronizing instrument editors hosted
1050          in the sampler's process to safely edit instruments while playing
1051          without a crash (hopefully) by either suspending single regions
1052          wherever possible or if unavoidable whole engine(s)
1053        - fixed several issues in fundamental "Thread" class: set scheduling
1054          policy and priority on thread level, set a minimum stack size for
1055          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1056          threads simply inherited properties of starting thread instead of
1057          setting their own policy and priority
1058        - minor fix in our automatic stack trace mechanism on crashes, the
1059          main process did not wait for the stack trace process to finish
1060          its output
1061        - fixed some minor memory leaks
1062        - reenabled assembly features support, at the moment only for
1063          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1064        - minor assembly fix in x86 features detection (don't use the PIC
1065          register, to avoid relocations in the text segment at runtime)
1066        - POSIX callback functions of Thread.h are hidden
1067    
1068      * MIDI driver:
1069        - dispatch bank select (MSB and LSB) messages
1070    
1071      * audio driver:
1072        - the ALSA audio output driver parameters now reflect the correct
1073          parameter value ranges for the respective selected sound card
1074          (patch by Till Wimmer, a bit fixed and extended)
1075    
1076      * Gigasampler format engine:
1077        - if a filter is used and EG2 finishes before EG1, let the voice
1078          die when EG2 has finished (this fixes a problem with clicks and
1079          voice starvation for some gigs)
1080        - playback is no longer disabled during instrument loading
1081        - all notes playing on a channel that changes its instrument keep
1082          playing with the old instrument until they get a note off
1083          command
1084        - EG fix: a release value of zero could cause noises or crash
1085        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1086        - EG fine tuning: when attack is zero the EG starts at a level
1087          above max sustain level, which means that there is a decay phase
1088          even if sustain is 100%
1089        - more EG fixes: the level could sometimes go below zero and cause
1090          noises or crashes
1091        - minor fix of EGDecay (patch by Toshi Nagata)
1092        - fixed compiler error when --enable-override-filter-type was
1093          supplied to the configure script (fixes #46)
1094        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1095          instead of a fix value
1096        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1097          127 (solo mode) only kill voices if the respective mode really
1098          changed
1099    
1100      * LSCP server:
1101        - fixed compile time error for old Bison versions
1102          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1103        - parser now supports extended ASCII character set
1104          (up to ASCII code 255, i.e. includes now umlauts and accents)
1105        - filename arguments in LSCP commands now allow to use escape
1106          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1107          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1108          code value like \xf2) (fixes bug #24)
1109        - the following LSCP commands now also support escape sequences for at
1110          least one of their text-based parameters (i.e. name, description):
1111          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1112          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1113          "SET DB_INSTRUMENT_DIRECTORY NAME",
1114          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1115          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1116          "FIND DB_INSTRUMENT_DIRECTORIES"
1117        - returns verbose syntax errors (line and column where syntax error
1118          occured, the unexpected character and the actually expected, possible
1119          character(s), the latter only if less than 5 possibilities)
1120        - made sure that LSCP syntax is not affected by gigedit locale
1121          settings
1122        - bugfix regarding strings parameter lists: all comma separated lists
1123          of strings were treated as being one string containing commas
1124          (fixes #57)
1125    
1126      * Bug fixes:
1127        - fixed crash occurring on certain LSCP scripts (Bug 39)
1128        - another thread safety fix for lscp "load engine" and "set
1129          channel audio output device"
1130        - fixed a crash which occurs when reassigning the same engine
1131          on a sampler channel with connected MIDI device
1132        - fixed a crash which occurs when changing the number of ports of a MIDI
1133          device connected to a sampler channel to number less then or equal
1134          to the index of the port to which the sampler channel is connected.
1135        - The previous bindings were not been disconnected when altering
1136          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1137          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1138        - The active stream/voice count statistic was incorrect.
1139        - notification events were not been sent for some sampler
1140          channel changes
1141        - added default min and max values to restrict the number of allowed
1142          audio output channels and MIDI input ports
1143        - the connection to the PCM interface is now closed when destroying
1144          an audio output device
1145        - files with slash in their path or filename could not be loaded
1146    
1147      * test cases:
1148        - updated and fixed (haven't been touched in a while)
1149    
1150    Version 0.4.0 (24 November 2006)
1151    
1152      * packaging changes:
1153        - changed deprecated copyright attribute to license; added ldconfig
1154          to post-(un)install steps; added devel package for liblinuxsampler;
1155          to linuxsampler.spec (RPM)
1156        - install necessary development header files for allowing 3rd party
1157          applications to link against liblinuxsampler
1158        - liblinuxsampler's API documentation can be generated with 'make docs'
1159          (Doxygen required)
1160        - added benchmark to automatically detect the best triangle LFO
1161          implementation (currently either an integer math solution or a
1162          di-harmonic approximation), automatic detection can be overriden
1163          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1164          configure script argument though (mandatory for cross-compilation)
1165        - do not automatically pick optimized gcc flags if the user already
1166          provided some on his own (as CXXFLAGS)
1167        - added compile time option to disable processing of All-Notes-Off MIDI
1168          messages
1169        - added compile time options to allow disabling the various audio and
1170          MIDI drivers
1171        - fixed automatic GCC CPU switch detection on PPC
1172          (patch by Ebrahim Mayat)
1173    
1174      * Gigasampler format engine:
1175        - extensive synthesis optimization
1176          (reimplementation of EGs and LFO(s), removed synthesis parameter
1177          prerendering and the synthesis parameter matrix in general, splitting
1178          each audio fragment into subfragments now where each subfragment uses
1179          constant pitch and filter coefficients. The volume coefficient is
1180          linearly interpolated inside a subfragment, unless
1181          --disable-interpolate-volume is set.)
1182        - fine tuning of the EG modulation parameters
1183        - improved filter cutoff calculation by adding support for the
1184          following gig parameters: Cutoff freq (used when no cutoff
1185          controller is defined), Control invert, Minimum cutoff, Velocity
1186          curve and Velocity range. The keyboard tracking now scales
1187          cutoff frequency instead of resonance.
1188        - added support for gig parameter Resonance.
1189        - fixed bug in sysex handling (patch by Juan Linietsky)
1190        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1191          which can be overridden with --enable-global-attenuation
1192        - EG fixes: made the length of "attack hold" stage more
1193          accurate. Release stage can now start before attack stage
1194          ends. Cancel release didn't work when sustain was zero. Attack
1195          time now has a minimal value to prevent clicks.
1196        - fixed pitch changes larger than one octave
1197        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1198        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1199          all modes can be altered via standard GM messages, that is CC5 for
1200          altering portamento time, CC65 for enabling / disabling portamento
1201          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1202        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1203          parameter) and crossfade
1204        - added support for the "attenuation controller threshold" gig
1205          parameter
1206        - added smoothing of volume changes caused by control change
1207          messages
1208        - sample loop parameters are now taken from the DimensionRegion
1209          instead of the wave chunk
1210        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1211          not equal to a power of two
1212        - reimplementation of the filter algorithm. The new filter is more
1213          accurate and supports all gig filter types, including bandreject
1214          and lowpass turbo.
1215        - real support for 24 bit samples - samples are not truncated to
1216          16 bits anymore
1217        - support for aftertouch (channel pressure, not polyphonic
1218          aftertouch)
1219        - LFO1 behaviour fixed (dampening from max volume instead of
1220          amplifying from 0)
1221    
1222      * LSCP server:
1223        - fixed application exit on broken pipe error (fixes bug #20)
1224        - fixed the notification messages delay due to lack of
1225          network activity (fixes bug #26)
1226        - fixed parser bug which occured on space(s) within device parameters
1227          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1228    
1229      * audio driver:
1230        - added aRts audio output driver (by no means RT safe)
1231    
1232      * MIDI driver:
1233        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1234          messages several times instead of once
1235        - API extension for MIDI drivers which already supply exact time stamps
1236          for events (i.e. for offline rendering based MIDI drivers)
1237        - added checks for bad MIDI data
1238    
1239      * linuxsampler application:
1240        - show available sampler engine types on startup
1241    
1242      * general changes:
1243        - support for muting sampler channels and solo mode of the same, two new
1244          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1245          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1246          introduced for this, the behavior is the same like on a mixer console
1247          (patch by Grigor Iliev, a bit adjusted). Also added configure option
1248          --enable-process-muted-channels which can be used to enable the
1249          processing of muted channels.
1250        - support for sostenuto pedal
1251        - support for monitoring the total number of active voices
1252          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1253          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1254        - fixed some memory management errors
1255        - fixed some concurrency problems that could lead to crashes when
1256          LSCP commands were executed
1257        - fixed crash when instrument loading failed previously on the same
1258          sampler channel (fixes bug #36)
1259    
1260    Version 0.3.3 (15 July 2005)
1261    
1262      * packaging changes:
1263        - fixed compilation with gcc 4.0
1264    
1265      * Gigasampler format engine:
1266        - LFO preprocessing was performed even though the respective LFO was
1267          disabled by the instrument patch (minor efficiency fix)
1268        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1269          for volume ramp downs in the same fragment (needed for current voice
1270          stealing implementation) then simply inform the user with a warning
1271          about possible click sounds and reduce the volume ramp down
1272          appropriately instead of cancelling the audio device connection
1273    
1274    Version 0.3.2 (24 June 2005)
1275    
1276    * packaging changes:    * packaging changes:

1280        './configure --disable-asm' (definitely not recommended)        './configure --disable-asm' (definitely not recommended)
1281        - fixed 'make dist' rule to include all necessary files
1282        - require automake (>= 1.5) for 'make -f Makefile.cvs'
1283          (due to 'dist-bzip2' automake option)
1284    
1285    * Gigasampler format engine:    * Gigasampler format engine:
1286      - support for the gig parameters for "release velocity response" curves      - support for the gig parameters for "release velocity response" curves
# Line 12  Version CVS HEAD (?) Line 1288  Version CVS HEAD (?)
1288      - volume of release triggered samples now depends on note-on velocity,      - volume of release triggered samples now depends on note-on velocity,
1289        note length and gig parameter "release trigger decay" instead of        note length and gig parameter "release trigger decay" instead of

1291      - revised voice stealing (fixes crash caused by voice stealing)      - revised voice stealing
1292              (fixes crash and endless loop caused by voice stealing)
1293        - don't reset scale tuning on instrument or audio output device change
1294        - handle key group conflicts right at the beginning of each fragment
1295          instead of when the respective voice is actually launched
1296          (fixes undefined behavior if stolen voices belonged to a key group -
1297          this case was followed by a "killed voice survived" error message)
1298        - fixed minor issue with null/silence samples
1299          (those stole voices even though they don't need a voice at all which
1300          resulted in "voice stealing didn't work out" messages)
1301        - don't reset volume, pan, pitch and MIDI controller values on

1306        - fixed LSCP event "CHANNEL_INFO" notification
1307          (e.g. did not notify on volume changes or MIDI program change events)
1308    
1309      * linuxsampler application:
1310        - added command line parameters --lscp-addr and --lscp-port to override
1311          default IP address and port of LSCP server
