# 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    
6      * general changes:
7        - fixed printf type errors (mostly in debug messages)
8        - use unique_ptr instead of auto_ptr when building with C++11
9        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10          allowing to sort data efficiently in real-time safe manner.
11        - RTList class: added methods for moving/inserting elements to arbitrary
12          position within a list.
13        - RTList class: added method fromPtr() for creating an Iterator object from
14          a raw element pointer.
15        - Attempt to partly fix resetting engine channels vs. resetting engine, an
16          overall cleanup of the Reset*(), ConnectAudioDevice(),
17          DisconnectAudioDevice() API methods would still be desirable though,
18          because the current situation is still inconsistent and error prone.
19        - Active voices are now internally grouped to "Note" objects, instead of
20          being directly assigned to a keyboard key. This allows more fine graded
21          processing of voices, which is i.e. required for certain instrument
22          script features.
23        - Fix: Release trigger voices were not spawned on sustain pedal up
24          (CC #64) events.
25        - Fix: Release trigger voices can now also distinguish correctly between
26          note-off and sustain pedal up events.
27        - All engines: Increased ramp speed of volume smoother and pan smoother
28          (while slow rate of crossfade smoother is preserved) to allow quick
29          volume and pan changes by instrument scripts for instance.
30    
31      * packaging changes:
32        - removed unnecessary dependency to libuuid
33          (originated by libgig's usage of it)
34        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
35          auto detect whether it (sh/c)ould output its messages in color.
36    
37      * Real-time instrument scripts:
38        - Implemented scheduler for delayed MIDI events and for suspended scripts.
39        - Built-in script function "wait()": implemented support for function's
40          "duration-us" argument, thus scripts using this function are now
41          correctly resumed after the requested amount of microseconds.
42        - Built-in script function "play_note()": implemented support for
43          function's "duration-us" argument, thus notes triggered with this
44          argument are now correctly released after the requested amount of
45          microseconds.
46        - Fix: script events were not cleared when engine channel was reset,
47          potentially causing undefined behavior.
48        - Fixed crash which happened when trying to reference an undeclared
49          variable.
50        - Built-in script function "play_note()": Added support for passing
51          special value -1 for "duration-us" argument, which will cause the
52          triggered note to be released once the original note was released.
53        - Instrument script classes now exported with the liblinuxsampler C++ API.
54        - Added new API method ScriptVM::syntaxHighlighting() which provides
55          a convenient syntax highlighting backend for external instrument
56          script editor applications.
57        - Added new C++ API class "ScriptVMFactory".
58        - Extended parser issues to provide not only first line and first
59          column, but also last line and last column of issue (thus marking
60          the precise span of the issue within the source code).
61        - Reload script automatically after being modified by an instrument
62          editor.
63        - NKSP language grammar correction: allow empty event handler bodies
64          like "on note end on".
65        - Implemented built-in script function "change_vol()".
66        - Implemented built-in script function "change_tune()".
67        - Implemented built-in script function "change_pan()".
68        - Implemented built-in script function "change_cutoff()".
69        - Implemented built-in script function "change_reso()".
70        - Implemented built-in script function "event_status()".
71        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
72          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
73          "event_status()" function.
74        - NKSP language: Added support for bitwise operators ".or.", ".and."
75          and ".not.".
76        - NKSP language scanner: Fixed IDs matching to require at least one
77          character (i.e. when matching function names or variable names).
78        - NKSP language scanner: disabled unusued rules.
79        - Fixed behavior of play_note() and note_off() functions which must
80          be distinguished engine internally from "real" MIDI note on/off
81          events in order to avoid misbehaviors like hanging notes.
82        - Implemented built-in script variable "$KSP_TIMER".
83        - Implemented built-in script variable "$NKSP_REAL_TIMER".
84        - Implemented built-in script variable "$NKSP_PERF_TIMER".
85        - Implemented built-in script variable "$ENGINE_UPTIME".
86        - Implemented built-in script function "inc()".
87        - Implemented built-in script function "dec()".
88        - NKSP language fix: division expressions were evaluated too often.
89        - NKSP language fix: string concatenation operator was right
90          associative instead of left (to right).
91        - NKSP language correction: allow empty statements in entire language
92          (i.e. "if end if").
93        - Implemented built-in script function "stop_wait()".
94        - Implemented built-in script variable "$NI_CALLBACK_ID".
95        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
96        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
97        - Added support for read-only built-in variables (respectively
98          handled by the script parser).
99        - Added built-in script constant "$NI_CB_TYPE_INIT".
100        - Added built-in script constant "$NI_CB_TYPE_NOTE".
101        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
102        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
103        - NKSP Language: Added support for user defined script functions.
104        - Implemented built-in script function "change_attack()".
105        - Implemented built-in script function "change_decay()".
106        - Implemented built-in script function "change_release()".
107        - Fixed all change_*() built-in script functions to apply their
108          synthesis parameter changes immediately in case the respective note
109          was triggered at the same time, instead of scheduling the parameter
110          change, especially because it would cause some parameter types's
111          changes either to be ramped (i.e. change_vol()) or other types even
112          to have not effect at all (i.e. change_attack()).
113        - Implemented built-in script function "sh_left()".
114        - Implemented built-in script function "sh_right()".
115        - Implemented built-in script function "min()".
116        - Implemented built-in script function "max()".
117        - NKSP Fix: "init" event handler was not always executed when a script
118          was loaded.
119        - NKSP built-in wait() script function: abort script execution if
120          a negative or zero wait time was passed as argument (since this is
121          a common indication of a bug either of the script or even of the
122          engine, which could lead to RT instability or even worse).
123        - ScriptVM: Implemented automatic suspension of RT safety
124          threatening scripts.
125        - Provide more user friendly error messages on syntax errors.
126        - Fixed NKSP parser warning "Not a statement" when assigning an
127          initializer list to an array variable.
128

133        - Mac OS X: support the new dir for Core Audio SDK
134        - Mac OS X: fixed building outside source directory
135        - made sure all source files for hostplugins are included when
136          doing "make dist"
137        - removed empty directories left from the cvs to svn migration
138        - fixed compilation with gcc 4.6.1
139        - another "make dist" fix, for the LV2 plugin
140        - made --enable-pthread-testcancel default on Mac OS X
141        - minor Makefile fix for building lscpparser when build and source
142          directories are separate
143        - Mac OS X: made it possible to specify plugin installation dir to
144          configure
145        - Mac OS X: Makefile fix for the install-strip target
146        - fixed compilation with gcc 4.7
147        - fixed configure script error with old autoconf versions
148        - lsatomic.h: use gcc provided atomic functions if building with

152          LDFLAGS="-Wl,--no-undefined" (#190)
153        - fixed compilation with Clang 3.2
154        - removed usage of deprecated Automake variable INCLUDES

162        - fixed build error on newer MinGW
163        - support building with older jack versions
164        - support building with spaces in vst sdk path
165        - enabled automake 'subdir-objects' option and moved external
166          source references (vst, au, asio) from makefiles to cpp files,
167          in order to get rid of warnings from automake 1.14
168    
169      * general changes:
170        - Refactoring: moved the independent code from
171          the Gigasampler format engine to base classes
172        - command line option '--profile' is currently disabled, since the
173          respective profiling code is currently broken
174        - Introduced support for optional environment variable
175          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
176          where the sampler shall look for instrument editor plugins
177          (patch by Luis Garrido, slightly modified).
178        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
179        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
180        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
181          note (in this implementation of the sampler its simply hard routed to
182          the 1st effect send of the sampler channel, no matter what the actual
183          effect type is)
184        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
185          note (in this implementation of the sampler its simply hard routed to
186          the 2nd effect send of the sampler channel, no matter what the actual
187          effect type is)
188        - implemented support for internal LADSPA effects
189        - raised limit of program change queue from 100 to 512
190          (as suggested by Alex Stone)
191        - implemented sine LFO, pulse LFO and saw LFO
192        - experimental support for per voice equalization
193        - added command line option --exec-after-init
194        - Introduced new C++ API method:
195          EngineChannel::InstrumentFileName(int index)
196          allowing to retrieve the whole list of files used for the loaded
197          instrument on an engine channel (a.k.a. part). Some GigaStudio
198          instruments for example are splitted over several files like
199          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
200        - Added new C++ API method Sampler::GetGlobalMaxVoices().
201        - Added new C++ API method Sampler::GetGlobalMaxStreams().
202        - Added new C++ API method Sampler::SetGlobalMaxVoices().
203        - Added new C++ API method Sampler::SetGlobalMaxStreams().
204        - Various "const" and "restrict" optimizations.
205        - all engines: add pan CC value to instrument pan parameter before
206          applying panning, instead of using two separate pan functions in
207          series (#182)
208        - added a lock guard class for exception safe mutex handling and
209          used it everywhere appropriate
210        - Immediately apply scale tuning changes to active voices.
211        - Exposed scale tuning to C++ API (along to the already existing standard
212          SysEx way).
213        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
214          and broken for ppc64. (Seq_cst loads and stores are actually not
215          used in LS, so the bug wasn't noticable.)
216        - lsatomic.h: added ARMv7 support
217        - Added support for multiple MIDI input ports per sampler channel (and
218          added various new C++ methods for this new feature / design change, old
219          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
220          as deprecated but are still there and should provide full behavior
221          backward compatibility).
222        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
223          unsafe and caused compilation error with clang 2.x).
224        - Bugfix: only process the latest MIDI program change event.
225        - Introducing the LSCP shell, which provides convenient control of the
226          sampler from the command line by providing LSCP aware features.
227        - VirtualMidiDevice: Added support for program change.
228        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
229        - VirtualMidiDevice: Added support for pitch bend.
230        - Aftertouch: extended API to explicitly handle channel pressure and
231          polyphonic key pressure events (so far polyphonic pressure was not
232          supported at all, and channel pressure was rerouted as CC128 but not
233          used so far).
234        - Added initial support for real-time instrument scripts. The script VM
235          code is shared by all sampler engine implemementations, however only the
236          gig file format currently provides support for storing instrument scripts
237          (as LinuxSampler extension to the original GigaStudio 4 format).
238    
239      * Gigasampler format engine:
240        - implemented the "round robin keyboard" dimension
241        - fixed round robin and random dimensions for cases when number of
242          dimension zones is not a power of two
243        - made round robin use a counter for each region instead of each
244          key
245        - bugfix: pitch LFO controller "internal+aftertouch" was broken
246        - bugfix: filter keyboard tracking was broken
247        - filter performance fix (an unnecessary copy was made of the
248          filter parameters in each sub fragment)
249        - handle special case when pan parameter in gig file has max or
250          min value
251        - Exclusive Groups: don't ever stop voices of the same note,
252          doesn't sound naturally with a drumkit
253        - fixed EG1 modulation when attack or release is zero
254        - Fixed support for 'aftertouch' attenuation controller.
255        - Fixed crash that happened with velocity split sounds under certain
256          conditions (see also previous commit on libgig).
257        - fixed behaviour of filter LFO
258    
259      * SFZ format engine:
260        - Initial implementation (not usable yet)
261        - added support for v2 multiple stage envelope generators
262        - added a fine-tuned v1 envelope generator instead of using the
263          one from the gig engine
264        - fixed memory leak and memory handling errors
265        - added support for trigger=first, trigger=legato and sw_previous
266        - allow non-numerical key values ("C#4" for example)
267        - "key" opcode now sets pitch_keycenter too
268        - fixed error when unloading instrument with same sample used by
269          multiple regions
270        - added some opcode aliases, like loopmode for loop_mode, to be
271          more compatible
272        - added support for trigger=release and rt_decay
273        - added support for off_mode=normal
274        - added support for random, seq_position, seq_length and volume
275        - added v1 LFO opcodes to parser (no support in engine yet)
276        - added support for amp_veltrack and amp_velcurve_N
277        - fine-tuned the default velocity curve
278        - added support for transpose
279        - fixed crash when using sw_down/up
280        - improved logic for sw_lokey/hikey/up/down/last
281        - added more v1 aliases to parser
282        - reduced memory usage for sfz data
283        - RT-safeness: avoid malloc in audio thread
284        - fixed a bug that could cause voice stealing to fail
285        - optimized sample lookup
286        - improved support for exclusive groups (group, off_by and
287          off_mode)
288        - added support for controller triggered regions (on_locc/on_hicc)
289        - added support for loop_mode=one_shot
290        - fixed playback of 16 bit wav files on big endian CPUs
291        - added support for Ogg Vorbis sample files
292        - use loop markers from sample file if loop_start and loop_end are
293          not set in sfz file
294        - implemeted filters. Filter types: lowpass, bandpass, bandreject

296          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
297          cutoff_cc, cutoff_chanaft.
298        - bugfix: zero ampeg_sustain didn't work
299        - added support for velocity effect on amplifier envelope time
300          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
301          ampeg_vel2release)
302        - added support for EG hold (ampeg_hold)

406          used
407        - bugfix: looping was disabled if loop_start was set to 0
408        - allow regions with end=-1 to turn off other regions using the

434        - AU bugfix: failed to destroy its audio/MIDI devices
435        - Listen to all interfaces on Mac OS X (INADDR_ANY)
436        - VST bugfix: If the host called resume() before and after
437          changing sample rate or block size, the number of channels was
438          incorrectly set to two. This caused silence in Cubase 5.
439        - save engine type (gig, sfz or sf2) in plugin state
440        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
441          64 bit Windows
442        - AU: changed number of output channels from one stereo to 16
443          stereo

457        - VST: fixed crashes on Linux Ardour and EnergyXT
458        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

471        - Changed instrument editor plugin interface, providing additional
472          informations like the EngineChannel for which the instrument editor was
473          spawned for. This allows the instrument editors to interact more actively
474          with the sampler.
475    
476      * MIDI driver:
477        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
478          the ALSA sequencer client name

480          there is no reason for this limit
481        - MME: fixed memory handling bug found with cppcheck
482        - MME: removed compiler warning
483        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
484          which allows to retrieve the list of CoreMIDI clients / ports and to connect
485          to them a la JACK, via the usual sampler APIs
486        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
487          the driver will automatically connect to other CoreMIDI clients' ports

492          virtual keyboards in frontends / instrument editors being stuck.
493        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
494        - Implemented missing handling of MIDI "running status".
495        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
496        - MME bugfix: driver wasn't closed properly
497        - CoreMIDI: automatically connect to all input sources by default (driver
498          parameter "AUTO_BIND").
499        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
500        - CoreMIDI: fixed minor memory leak
501    
502      * audio driver:
503        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
504        - JACK audio: react on sample rate changes.

507          RT context.
508        - ASIO driver: removed compiler warnings
509        - CoreAudio: fixed minor error handling bug
510        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
511        - JACK audio: return the JACK server's current sample rate as default value
512          for audio device parameter "SAMPLERATE" (fixes #166).

562        - Added support for built-in LSCP reference documentation, which will
563          automatically show the relevant LSCP reference section on screen as soon

625        - bugfix: calling SET VOICES (which Fantasia does on start and
626          refresh) could cause instruments to be unloaded
627        - Mac OS X: fixed name collision of enum in EffectControl and
628          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
629        - Mac OS X: fixed hanging threads
630        - Windows: disabled the previous thread fix on non-Mac systems, as

632        - Fixed possible crashes due to corrupted MIDI/audio device list
633          after MIDI/audio device creation failure
634        - When creating MIDI instrument map entries with "PERSISTENT" type, the
635          instruments were uselessly precached with zero samples, however it still
636          took the full preloading time and on 1st program change the respective
637          instrument was completely reloaded again.
638        - fixed handling of rapid bank select and program change messages
639          sent to the same sampler channel (patch from the Open Octave
640          project, slightly adjusted)

653          introduced in previous fix)
654        - fixed crash when a channel received a program change while
655          playing a note in a key group
656        - fixed erroneous error message piping in VoiceBase.h
657          (labelled "Disk stream not available in time")
658        - Update effects on sample rate & period size changes (to avoid
659          crashes and noise on such transitions).
660        - ignore missing LADSPA paths without ignoring valid LADSPA paths
661          (fixes #208)
662        - Fixed bug in LSCP grammar definition which caused a statement like
663          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
664          practically irrelevant, however it caused problems with the new LSCP
665          shell's auto completion feature).
666        - Fixed MIDI program change messages being ignored if quickly executed
667          after each other (fixes #231).
668    
669    Version 1.0.0 (31 July 2009)
670    
671      * packaging changes:
672        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

694          (fixes bug #70, patch by Ronald Baljeu)
695        - fixed endless loop which occured when loading an instrument editor
696          plugin DLL on Windows systems failed
697        - fixed memory leaks that occurred when liblinuxsampler was unloaded
698        - optimized the SynchronizedConfig class so it doesn't wait
699          unnecessarily long after an update
700        - added support for notifying instrument editors on note-on / note-off
701          events (e.g. to highlight the pressed keys on the virtual keyboard
702          of gigedit)
703        - added support for triggering notes by instrument editors (see above)
704        - be verbose on DLL load errors (on Linux)
705        - fixed di-harmonic triangle LFO implementation (this LFO implementation
706          is only used by very few systems, most pick the int math
707          implementation, which is usually faster)
708        - fixes for audio drivers with varying buffer sizes
709        - experimental support for running LinuxSampler as a DSSI, LV2 and
710          VST plugin
711        - notification events for stream/voice count statistics are now sent
712          only when there are actual changes
713        - added memory ordering constraints to improve stability on
714          multi-core and multi-cpu systems
715        - maximum voices and disk streams can now be altered at runtime
716        - fixed CPU feature detection on x86_64 (maybe fixes #108)
717        - automatic stacktrace mechanism is now turned off by default and can
718          be switched on by command line option "--stacktrace" (the automatic
719          stacktrace mechanism seems to be broken on most systems at the moment)
720        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
721          a pointer to the launched InstrumentEditor object
722        - added optional 3rd party user data parameter for following
723          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
724          InstrumentEditor::Launch(),
725          InstrumentManager::LaunchInstrumentEditor()
726        - theoretical fix: made SynchronizedConfig follow C++0x memory
727          model more strictly
728        - fixes for using large audio device buffers
729        - Windows: add the installation directory to the DLL search path
730          when loading an editor plugin (solves problems with VST and
731          gigedit on systems with other GTK versions installed)
732        - updated linuxsampler man page
733    
734      * audio driver:
735        - removed the nonsense audio channel constraint (which was hard coded to
736          max. 100 audio channels) for most audio drivers
737        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
738          opposed to the LSCP specs
739        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
740          reflected the wrong value
741        - fixed a memory management bug in ASIO driver
742        - Makefile fix: JACK_CFLAGS wasn't used
743        - JACK: use jack_client_open instead of the deprecated
744          jack_client_new
745        - added (experimental) CoreAudio driver
746        - applied old fixes to the ASIO driver that were included in the
747          previous binary release but accidentally never committed to CVS
748          (fixes #117)
749        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
750          win64)
751        - VST: added support for sample rate and buffer size changes
752        - VST: close editor (Fantasia) when the VST is removed
753        - VST: avoid opening Fantasia more than once for each VST instance
754        - VST: export main function as "main" on Linux too (fix for
755          energyXT)
756        - VST: changed number of output channels from one stereo to 16
757          stereo
758        - added channel routing, fxsends and midi maps to the settings
759          stored in the plugin state
760        - performance optimization of AudioChannel::MixTo() and
761          AudioChannel::CopyTo() methods using GCC vector exensions
762          (if available)
763        - ASIO fixes: avoid initializing the device twice, avoid throwing
764          exception when getting parameters from a disconnected device
765    
766      * MIDI driver:
767        - added JACK MIDI driver
768        - dispatch bank select as ordinary CC as well, the user might seriously
769          want to (mis)use it for some purpose ("fixed" in all current MIDI
770          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
771        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
772          CoreMidi or AU
773        - fixed mingw-w64 compilation error in MME driver
774        - made program change handling in MIDI thread real-time safe by
775          moving the logic to a non-RT thread
776        - fixed minor memory leak in ALSA driver
777    
778      * instruments database:
779        - avoid time consuming samples scanning when adding instruments
780          to the instruments database
781        - added support for handling lost files in the instruments database
782        - Implemented option for adding instruments in separate directories
783          in the instruments database
784          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
785        - work-around for missing fnmatch function on Windows to make
786          instrument database compilable
787        - added instrument database support on Windows
788          works with both standalone mode and VST plugin.
789          the instruments DB file is located in
790          %USERPROFILE%\.linuxsampler\instruments.db which allows different
791          databases for each windows user
792          if no DB is present it automatically creates the .linuxsampler subdir
793          and then creates an empty DB
794        - fixed recursive import, which was broken on Windows
795    
796      * Gigasampler format engine:
797        - fixed a memory leak that could happen when a channel was deleted
798          while notes were playing
799        - made it possible to load an instrument even if the audio thread
800          isn't running
801        - added partial support for the "Controller Triggered" MIDI rule,
802          enough for piano gigs with pedal noise samples
803        - minor fix: only mark FX sends as being modified if really the
804          respective FX send MIDI controller was used
805        - added support for GM global device volume SysEx message
806          (can be selected at compile time to either apply globally to the
807          whole sampler [default] or only to the sampler channels that are
808          connected to the respective MIDI input port the SysEx message arrived
809          on)
810        - bugfix: notes triggered at position 0 in the audio buffer were
811          sometimes wrongly killed in the same buffer, causing no sound to
812          be played
813        - added support for chromatic / drumkit mode Roland GS Sysex message
814          which is usally used to switch a part between chromatic sounds and
815          drumkit sounds (as opposed to their common default setting of MIDI
816          part 10 being a drumkit part and all other ones chromatic parts), in
817          LS however one can switch between the first 16 MIDI instrument maps
818          defined for the sampler
819        - made it possible to create multiple sample channels even if the
820          audio thread isn't running
821        - fixed crash when removing channel with active voices (#116)
822        - bugfix: on sample reference changes (instrument editor), only
823          un-cache the respective sample if it's really not used by any
824          sampler engine anymore
825        - re-cache samples in case they were changed by an instrument editor,
826          e.g. when a sample was added while playing (#82)
827        - fixed hanging notes which occured when note-off event had the exact
828          same time stamp as the voice's note-on event and occured both in the
829          same audio fragment cycle (fixes bug #112)
830        - added support for the "fine tune" and "pitch bend range"
831          instrument-level gig parameters
832        - fixed minor artifacts in pitch bend handling
833        - added support for GS Reset SysEx message
834        - allow gig files to use unlimited downward pitch shifting
835        - added a limit check for upward pitch shifting
836        - bugfix: sometimes, when playing a note twice fast, the second
837          note was silent
838        - fixed crash happening when a pitch bend event arrived at the
839          same time a new instrument was loading
840    
841      * LSCP server:
842        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
843          react on MIDI data arriving on certain sampler channels (so far only
844          Note-On and Note-Off events are sent via this LSCP event)
845        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
846          react on MIDI data arriving on certain MIDI input devices (so far only
847          Note-On and Note-Off events are sent via this LSCP event)
848        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
849          SET DB_INSTRUMENT FILE_PATH
850        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
851          frontends to send MIDI messages to specific sampler channel
852        - added two additional fields to GET FILE INSTRUMENT INFO command -
853          KEY_BINDINGS and KEYSWITCH_BINDINGS
854        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
855          was incorrect
856        - Optimized the retrieval of the MIDI instrument mappings
857        - added new LSCP command "SET VOICES" to globally alter the maximum
858          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
859          be triggered respectively
860        - added new LSCP command "SET STREAMS" to globally alter the maximum
861          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
862          which will be triggered respectively
863        - bugfix: retry if "select" returns EINTR (this fixes a crash when
864          a gigedit file dialog is opened)
865        - close all connections when LSCPServer is deleted
866        - hard close of all sockets on exit
867        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
868          driver
869    
870      * Bug fixes:
871        - fixed a crash which occurs when removing a sampler channel waiting
872          to start instrument loading after another channel
873        - fixed a crash which occurs when removing a sampler channel with
874          instrument loading in progress (bug #113)
875        - fixed termination caused by uncaught exception when adding MIDI
876          instrument with PERSISTENT load mode
877        - fixed possible iterator invalidations when resetting the sampler
878        - fixed memory leaks when issuing the following LSCP commands:
879          GET AUDIO_OUTPUT_DRIVER INFO
880          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
881          GET MIDI_INPUT_DRIVER INFO
882          GET MIDI_INPUT_DRIVER_PARAMETER INFO
883        - fixed possible compilation error when sqlite is not present
884        - fixed orphaned pointers when setting maximum voices limit (bug #118)
885        - fixed crash when changing the audio output device of a sampler
886          channel with loaded instrument and start playing notes
887        - fixed endless loop in Engine::SuspendAll() (bug #120)
888        - fixed a low-level atomic load function that was broken on 64-bit
889          PowerPC, which probably could cause crashes on that platform
890        - fixed a memory management error which could cause a crash when a
891          plugin was unloaded
892        - bugfix: two private structs had the same name, which could cause
893          problems if the linker chose the wrong constructor
894        - fixed low-level ConditionServer usage bug that caused lockups on
895          Windows
896    
897    
898    Version 0.5.1 (6 December 2007)
899    
900      * packaging changes:
901        - added autoconf checks for pthread library
902        - added autoconf check for pthread bug found on certain NPTL-enabled
903          glibc versions (see Gentoo bug report #194076)
904        - added autoconf checks for MS Windows
905    
906      * general changes:
907        - bugfix: the thread used by an editor plugin didn't die when the
908          editor closed
909        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
910          out all the space. operator--() did not apply size_mask after
911          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
912          order to avoid problems with the _NonVolatileReader functions.
913        - bugfix: Stream.h: added a missing divide by BytesPerSample in
914          GetWriteSpace(). Since this function is currently only used in
915          the stream's qsort() compare function, it didn't trigger any
916          bugs.
917        - Resampler.h, Synthesizer.h: cubic interpolation now works in
918          24bit mode too. Faster method to read 24bit words on little
919          endian machines (x86): replaced 3 byte reads + shifts with a 1
920          unaligned 32bit read and shift
921        - experimental support for MS Windows (MIDI input via MME, AUDIO
922          output via ASIO)
923        - made handling of SIGINT signal (Ctrl-C) a bit more robust
924        - support for monitoring the total number of active disk streams
925          (new LSCP commands: GET TOTAL_STREAM_COUNT,
926          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
927    
928      * AUDIO driver:
929        - added Windows ASIO low latency audio driver
930    
931      * MIDI driver:
932        - added MME Windows MIDI driver
933    
934      * LSCP server:
935        - added support for Windows style path / filenames, however with
936          forward slash path separators instead of backslash
937          (i.e. "C:/foo/bar.gig")
938        - allow naughty liblscp to send non-string device parameters within
939          apostrophes as well
940        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
941          "LIST FILE INSTRUMENTS <file>" and
942          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
943          about an arbitrary instrument file on the system where the sampler is
944          running on
945    
946    Version 0.5.0 (15 October 2007)
947    
948      * packaging changes:
949        - config.h is not going to be installed along with liblinuxsampler's
950          API header files anymore
951        - only the API relevant header (and source) files will be exported to
952          the Doxygen API documentation (explicitly listed in Doxyfile.in)
953        - added completely new XCode project files for Mac OSX which is now
954          capable to execute our autoconf environment, thus no need anymore
955          to maintain the compile time configuration file (osx/version.h) for
956          OSX manually (patch by Toshi Nagata)
957        - fixed buggy boolean --enable-foo / --disable-foo configure script
958          parameters
959        - global.h now only covers global definitions that are needed for the
960          C++ API header files, all implementation internal global definitions
961          are now in global_private.h
962        - atomic.h is not exposed to the C++ API anymore
963        - no need to include config.h anymore for using LS's API header files
964        - fixed warnings in API doc generation
965    
966      * general changes:
967        - replaced the old, confusing MIDI program change mechanism by a
968          flexible MIDI instrument mapper which allows to map arbitrary
969          (MIDI bank, MIDI program) pairs with arbitrary
970          (engine type, instrument file, file index) triplets which will be
971          loaded on the respective channel when such MIDI program change
972          messages arrive, beside that, each entry allows to define a life-time
973          strategy for the instrument, so the user can define whether the
974          instrument should i.e. be permanently loaded (to be able to switch
975          quickly among sounds) or i.e. loaded just on demand when the
976          respective program change arrives (to safe RAM space), as well as a
977          global volume factor for each entry, so the user can adjust the volume
978          dynamic of his mapped instrument collection without having to modify
979          the instrument files, also one can manage arbitrary amount of such
980          MIDI instrument maps and assign each sampler channel individually
981          a certain map, so that i.e. separation of normal instruments and
982          drumkits is possible
983        - new notification events for tracking changes to audio/MIDI devices,
984          MIDI instrument maps, MIDI instruments, FX sends, global volume.
985        - sampler was limited to load max. 200 instruments in the background
986          due to a constant size RingBuffer FIFO which is now replaced by a
987          dynamic (unlimited) size std::list FIFO
988        - added FX sends, these allow to route audio signals to arbitrary audio
989          output channels for being processed by external effect processors
990          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
991          controllers
992        - global (sampler wide) volume can now be controlled at runtime
993        - Implemented new, improved notification system
994        - fixed compilation errors regarding OSX
995          (patch by Toshi Nagata)
996        - implemented instruments database
997        - added support for escape sequences to the instruments database
998        - added highly experimental support for on-the-fly instrument editing
999          within the sampler's process (by using instrument editor plugins),
1000          you'll notice the new "Registered instrument editors:" message on
1001          startup, added a new LSCP command:
1002          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1003          to spawn a matching instrument editor for the instrument on the
1004          given sampler channel, the plugin path can be overridden at compile
1005          time with ./configure --enable-plugin-dir=/some/dir
1006        - added experimental code for synchronizing instrument editors hosted
1007          in the sampler's process to safely edit instruments while playing
1008          without a crash (hopefully) by either suspending single regions
1009          wherever possible or if unavoidable whole engine(s)
1010        - fixed several issues in fundamental "Thread" class: set scheduling
1011          policy and priority on thread level, set a minimum stack size for
1012          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1013          threads simply inherited properties of starting thread instead of
1014          setting their own policy and priority
1015        - minor fix in our automatic stack trace mechanism on crashes, the
1016          main process did not wait for the stack trace process to finish
1017          its output
1018        - fixed some minor memory leaks
1019        - reenabled assembly features support, at the moment only for
1020          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1021        - minor assembly fix in x86 features detection (don't use the PIC
1022          register, to avoid relocations in the text segment at runtime)
1023        - POSIX callback functions of Thread.h are hidden
1024    
1025      * MIDI driver:
1026        - dispatch bank select (MSB and LSB) messages
1027    
1028      * audio driver:
1029        - the ALSA audio output driver parameters now reflect the correct
1030          parameter value ranges for the respective selected sound card
1031          (patch by Till Wimmer, a bit fixed and extended)
1032    
1033      * Gigasampler format engine:
1034        - if a filter is used and EG2 finishes before EG1, let the voice
1035          die when EG2 has finished (this fixes a problem with clicks and
1036          voice starvation for some gigs)
1037        - playback is no longer disabled during instrument loading
1038        - all notes playing on a channel that changes its instrument keep
1039          playing with the old instrument until they get a note off
1040          command
1041        - EG fix: a release value of zero could cause noises or crash
1042        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1043        - EG fine tuning: when attack is zero the EG starts at a level
1044          above max sustain level, which means that there is a decay phase
1045          even if sustain is 100%
1046        - more EG fixes: the level could sometimes go below zero and cause
1047          noises or crashes
1048        - minor fix of EGDecay (patch by Toshi Nagata)
1049        - fixed compiler error when --enable-override-filter-type was
1050          supplied to the configure script (fixes #46)
1051        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1052          instead of a fix value
1053        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1054          127 (solo mode) only kill voices if the respective mode really
1055          changed
1056    
1057      * LSCP server:
1058        - fixed compile time error for old Bison versions
1059          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1060        - parser now supports extended ASCII character set
1061          (up to ASCII code 255, i.e. includes now umlauts and accents)
1062        - filename arguments in LSCP commands now allow to use escape
1063          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1064          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1065          code value like \xf2) (fixes bug #24)
1066        - the following LSCP commands now also support escape sequences for at
1067          least one of their text-based parameters (i.e. name, description):
1068          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1069          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1070          "SET DB_INSTRUMENT_DIRECTORY NAME",
1071          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1072          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1073          "FIND DB_INSTRUMENT_DIRECTORIES"
1074        - returns verbose syntax errors (line and column where syntax error
1075          occured, the unexpected character and the actually expected, possible
1076          character(s), the latter only if less than 5 possibilities)
1077        - made sure that LSCP syntax is not affected by gigedit locale
1078          settings
1079        - bugfix regarding strings parameter lists: all comma separated lists
1080          of strings were treated as being one string containing commas
1081          (fixes #57)

1083      * Bug fixes:
1084        - fixed crash occurring on certain LSCP scripts (Bug 39)
1085        - another thread safety fix for lscp "load engine" and "set
1086          channel audio output device"
1087        - fixed a crash which occurs when reassigning the same engine
1088          on a sampler channel with connected MIDI device
1089        - fixed a crash which occurs when changing the number of ports of a MIDI
1090          device connected to a sampler channel to number less then or equal
1091          to the index of the port to which the sampler channel is connected.
1092        - The previous bindings were not been disconnected when altering
1093          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1094          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1095        - The active stream/voice count statistic was incorrect.
1096        - notification events were not been sent for some sampler
1097          channel changes
1098        - added default min and max values to restrict the number of allowed
1099          audio output channels and MIDI input ports
1100        - the connection to the PCM interface is now closed when destroying
1101          an audio output device
1102        - files with slash in their path or filename could not be loaded
