# 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    
126    Version 2.0.0 (15 July 2015)

133          doing "make dist"
134        - removed empty directories left from the cvs to svn migration
135        - fixed compilation with gcc 4.6.1
136        - another "make dist" fix, for the LV2 plugin
137        - made --enable-pthread-testcancel default on Mac OS X
138        - minor Makefile fix for building lscpparser when build and source
139          directories are separate
140        - Mac OS X: made it possible to specify plugin installation dir to
141          configure
142        - Mac OS X: Makefile fix for the install-strip target
143        - fixed compilation with gcc 4.7
144        - fixed configure script error with old autoconf versions

159        - fixed build error on newer MinGW
160        - support building with older jack versions
161        - support building with spaces in vst sdk path
162        - enabled automake 'subdir-objects' option and moved external
163          source references (vst, au, asio) from makefiles to cpp files,
164          in order to get rid of warnings from automake 1.14
165    
166      * general changes:
167        - Refactoring: moved the independent code from
168          the Gigasampler format engine to base classes
169        - command line option '--profile' is currently disabled, since the
170          respective profiling code is currently broken
171        - Introduced support for optional environment variable
172          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
173          where the sampler shall look for instrument editor plugins
174          (patch by Luis Garrido, slightly modified).
175        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
176        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
177        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
178          note (in this implementation of the sampler its simply hard routed to
179          the 1st effect send of the sampler channel, no matter what the actual
180          effect type is)
181        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
182          note (in this implementation of the sampler its simply hard routed to
183          the 2nd effect send of the sampler channel, no matter what the actual
184          effect type is)
185        - implemented support for internal LADSPA effects
186        - raised limit of program change queue from 100 to 512
187          (as suggested by Alex Stone)
188        - implemented sine LFO, pulse LFO and saw LFO
189        - experimental support for per voice equalization
190        - added command line option --exec-after-init
191        - Introduced new C++ API method:
192          EngineChannel::InstrumentFileName(int index)
193          allowing to retrieve the whole list of files used for the loaded
194          instrument on an engine channel (a.k.a. part). Some GigaStudio
195          instruments for example are splitted over several files like
196          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
197        - Added new C++ API method Sampler::GetGlobalMaxVoices().
198        - Added new C++ API method Sampler::GetGlobalMaxStreams().
199        - Added new C++ API method Sampler::SetGlobalMaxVoices().
200        - Added new C++ API method Sampler::SetGlobalMaxStreams().
201        - Various "const" and "restrict" optimizations.
202        - all engines: add pan CC value to instrument pan parameter before
203          applying panning, instead of using two separate pan functions in
204          series (#182)
205        - added a lock guard class for exception safe mutex handling and
206          used it everywhere appropriate
207        - Immediately apply scale tuning changes to active voices.
208        - Exposed scale tuning to C++ API (along to the already existing standard
209          SysEx way).
210        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
211          and broken for ppc64. (Seq_cst loads and stores are actually not
212          used in LS, so the bug wasn't noticable.)
213        - lsatomic.h: added ARMv7 support
214        - Added support for multiple MIDI input ports per sampler channel (and
215          added various new C++ methods for this new feature / design change, old
216          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
217          as deprecated but are still there and should provide full behavior
218          backward compatibility).
219        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
220          unsafe and caused compilation error with clang 2.x).
221        - Bugfix: only process the latest MIDI program change event.
222        - Introducing the LSCP shell, which provides convenient control of the
223          sampler from the command line by providing LSCP aware features.
224        - VirtualMidiDevice: Added support for program change.
225        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
226        - VirtualMidiDevice: Added support for pitch bend.
227        - Aftertouch: extended API to explicitly handle channel pressure and
228          polyphonic key pressure events (so far polyphonic pressure was not
229          supported at all, and channel pressure was rerouted as CC128 but not
230          used so far).
231        - Added initial support for real-time instrument scripts. The script VM
232          code is shared by all sampler engine implemementations, however only the
233          gig file format currently provides support for storing instrument scripts
234          (as LinuxSampler extension to the original GigaStudio 4 format).
235    
236      * Gigasampler format engine:
237        - implemented the "round robin keyboard" dimension
238        - fixed round robin and random dimensions for cases when number of
239          dimension zones is not a power of two
240        - made round robin use a counter for each region instead of each
241          key
242        - bugfix: pitch LFO controller "internal+aftertouch" was broken
243        - bugfix: filter keyboard tracking was broken
244        - filter performance fix (an unnecessary copy was made of the
245          filter parameters in each sub fragment)
246        - handle special case when pan parameter in gig file has max or
247          min value
248        - Exclusive Groups: don't ever stop voices of the same note,
249          doesn't sound naturally with a drumkit
250        - fixed EG1 modulation when attack or release is zero
251        - Fixed support for 'aftertouch' attenuation controller.
252        - Fixed crash that happened with velocity split sounds under certain
253          conditions (see also previous commit on libgig).
254        - fixed behaviour of filter LFO
255    
256      * SFZ format engine:
257        - Initial implementation (not usable yet)
258        - added support for v2 multiple stage envelope generators
259        - added a fine-tuned v1 envelope generator instead of using the
260          one from the gig engine
261        - fixed memory leak and memory handling errors
262        - added support for trigger=first, trigger=legato and sw_previous
263        - allow non-numerical key values ("C#4" for example)
264        - "key" opcode now sets pitch_keycenter too
265        - fixed error when unloading instrument with same sample used by
266          multiple regions
267        - added some opcode aliases, like loopmode for loop_mode, to be
268          more compatible
269        - added support for trigger=release and rt_decay
270        - added support for off_mode=normal
271        - added support for random, seq_position, seq_length and volume
272        - added v1 LFO opcodes to parser (no support in engine yet)
273        - added support for amp_veltrack and amp_velcurve_N
274        - fine-tuned the default velocity curve
275        - added support for transpose
276        - fixed crash when using sw_down/up
277        - improved logic for sw_lokey/hikey/up/down/last
278        - added more v1 aliases to parser
279        - reduced memory usage for sfz data
280        - RT-safeness: avoid malloc in audio thread
281        - fixed a bug that could cause voice stealing to fail
282        - optimized sample lookup
283        - improved support for exclusive groups (group, off_by and
284          off_mode)
285        - added support for controller triggered regions (on_locc/on_hicc)
286        - added support for loop_mode=one_shot
287        - fixed playback of 16 bit wav files on big endian CPUs
288        - added support for Ogg Vorbis sample files
289        - use loop markers from sample file if loop_start and loop_end are
290          not set in sfz file
291        - implemeted filters. Filter types: lowpass, bandpass, bandreject
292          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
293          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
294          cutoff_cc, cutoff_chanaft.
295        - bugfix: zero ampeg_sustain didn't work
296        - added support for velocity effect on amplifier envelope time
297          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and

403          used
404        - bugfix: looping was disabled if loop_start was set to 0
405        - allow regions with end=-1 to turn off other regions using the

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

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

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

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

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

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

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

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

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

692        - fixed endless loop which occured when loading an instrument editor
693          plugin DLL on Windows systems failed
694        - fixed memory leaks that occurred when liblinuxsampler was unloaded
695        - optimized the SynchronizedConfig class so it doesn't wait
696          unnecessarily long after an update
697        - added support for notifying instrument editors on note-on / note-off
698          events (e.g. to highlight the pressed keys on the virtual keyboard
699          of gigedit)
700        - added support for triggering notes by instrument editors (see above)
701        - be verbose on DLL load errors (on Linux)
702        - fixed di-harmonic triangle LFO implementation (this LFO implementation
703          is only used by very few systems, most pick the int math
704          implementation, which is usually faster)
705        - fixes for audio drivers with varying buffer sizes
706        - experimental support for running LinuxSampler as a DSSI, LV2 and
707          VST plugin
708        - notification events for stream/voice count statistics are now sent
709          only when there are actual changes
710        - added memory ordering constraints to improve stability on
711          multi-core and multi-cpu systems
712        - maximum voices and disk streams can now be altered at runtime
713        - fixed CPU feature detection on x86_64 (maybe fixes #108)
714        - automatic stacktrace mechanism is now turned off by default and can
715          be switched on by command line option "--stacktrace" (the automatic
716          stacktrace mechanism seems to be broken on most systems at the moment)
717        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
718          a pointer to the launched InstrumentEditor object
719        - added optional 3rd party user data parameter for following
720          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
721          InstrumentEditor::Launch(),
722          InstrumentManager::LaunchInstrumentEditor()
723        - theoretical fix: made SynchronizedConfig follow C++0x memory
724          model more strictly
725        - fixes for using large audio device buffers
726        - Windows: add the installation directory to the DLL search path
727          when loading an editor plugin (solves problems with VST and
728          gigedit on systems with other GTK versions installed)
729        - updated linuxsampler man page
730    
731      * audio driver:
732        - removed the nonsense audio channel constraint (which was hard coded to
733          max. 100 audio channels) for most audio drivers
734        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
735          opposed to the LSCP specs
736        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
737          reflected the wrong value
738        - fixed a memory management bug in ASIO driver
739        - Makefile fix: JACK_CFLAGS wasn't used
740        - JACK: use jack_client_open instead of the deprecated
741          jack_client_new
742        - added (experimental) CoreAudio driver
743        - applied old fixes to the ASIO driver that were included in the
744          previous binary release but accidentally never committed to CVS
745          (fixes #117)
746        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
747          win64)
748        - VST: added support for sample rate and buffer size changes
749        - VST: close editor (Fantasia) when the VST is removed
750        - VST: avoid opening Fantasia more than once for each VST instance
751        - VST: export main function as "main" on Linux too (fix for
752          energyXT)
753        - VST: changed number of output channels from one stereo to 16
754          stereo
755        - added channel routing, fxsends and midi maps to the settings
756          stored in the plugin state
757        - performance optimization of AudioChannel::MixTo() and
758          AudioChannel::CopyTo() methods using GCC vector exensions
759          (if available)
760        - ASIO fixes: avoid initializing the device twice, avoid throwing
761          exception when getting parameters from a disconnected device
762    
763      * MIDI driver:
764        - added JACK MIDI driver
765        - dispatch bank select as ordinary CC as well, the user might seriously
766          want to (mis)use it for some purpose ("fixed" in all current MIDI
767          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
768        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
769          CoreMidi or AU
770        - fixed mingw-w64 compilation error in MME driver
771        - made program change handling in MIDI thread real-time safe by
772          moving the logic to a non-RT thread
773        - fixed minor memory leak in ALSA driver
774    
775      * instruments database:
776        - avoid time consuming samples scanning when adding instruments
777          to the instruments database
778        - added support for handling lost files in the instruments database
779        - Implemented option for adding instruments in separate directories
780          in the instruments database
781          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
782        - work-around for missing fnmatch function on Windows to make
783          instrument database compilable
784        - added instrument database support on Windows
785          works with both standalone mode and VST plugin.
786          the instruments DB file is located in
787          %USERPROFILE%\.linuxsampler\instruments.db which allows different
788          databases for each windows user
789          if no DB is present it automatically creates the .linuxsampler subdir
790          and then creates an empty DB
791        - fixed recursive import, which was broken on Windows
792    
793      * Gigasampler format engine:
794        - fixed a memory leak that could happen when a channel was deleted
795          while notes were playing
796        - made it possible to load an instrument even if the audio thread
797          isn't running
798        - added partial support for the "Controller Triggered" MIDI rule,
799          enough for piano gigs with pedal noise samples
800        - minor fix: only mark FX sends as being modified if really the
801          respective FX send MIDI controller was used
802        - added support for GM global device volume SysEx message
803          (can be selected at compile time to either apply globally to the
804          whole sampler [default] or only to the sampler channels that are
805          connected to the respective MIDI input port the SysEx message arrived
806          on)
807        - bugfix: notes triggered at position 0 in the audio buffer were
808          sometimes wrongly killed in the same buffer, causing no sound to
809          be played
810        - added support for chromatic / drumkit mode Roland GS Sysex message
811          which is usally used to switch a part between chromatic sounds and
812          drumkit sounds (as opposed to their common default setting of MIDI
813          part 10 being a drumkit part and all other ones chromatic parts), in
814          LS however one can switch between the first 16 MIDI instrument maps
815          defined for the sampler
816        - made it possible to create multiple sample channels even if the
817          audio thread isn't running
818        - fixed crash when removing channel with active voices (#116)
819        - bugfix: on sample reference changes (instrument editor), only
820          un-cache the respective sample if it's really not used by any
821          sampler engine anymore
822        - re-cache samples in case they were changed by an instrument editor,
823          e.g. when a sample was added while playing (#82)
824        - fixed hanging notes which occured when note-off event had the exact
825          same time stamp as the voice's note-on event and occured both in the
826          same audio fragment cycle (fixes bug #112)
827        - added support for the "fine tune" and "pitch bend range"
828          instrument-level gig parameters
829        - fixed minor artifacts in pitch bend handling
830        - added support for GS Reset SysEx message
831        - allow gig files to use unlimited downward pitch shifting
832        - added a limit check for upward pitch shifting
833        - bugfix: sometimes, when playing a note twice fast, the second
834          note was silent
835        - fixed crash happening when a pitch bend event arrived at the
836          same time a new instrument was loading
837    
838      * LSCP server:
839        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
840          react on MIDI data arriving on certain sampler channels (so far only
841          Note-On and Note-Off events are sent via this LSCP event)
842        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
843          react on MIDI data arriving on certain MIDI input devices (so far only
844          Note-On and Note-Off events are sent via this LSCP event)
845        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
846          SET DB_INSTRUMENT FILE_PATH
847        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
848          frontends to send MIDI messages to specific sampler channel
849        - added two additional fields to GET FILE INSTRUMENT INFO command -
850          KEY_BINDINGS and KEYSWITCH_BINDINGS
851        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
852          was incorrect
853        - Optimized the retrieval of the MIDI instrument mappings
854        - added new LSCP command "SET VOICES" to globally alter the maximum
855          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
856          be triggered respectively
857        - added new LSCP command "SET STREAMS" to globally alter the maximum
858          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
859          which will be triggered respectively
860        - bugfix: retry if "select" returns EINTR (this fixes a crash when
861          a gigedit file dialog is opened)
862        - close all connections when LSCPServer is deleted
863        - hard close of all sockets on exit
864        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
865          driver
866    
867      * Bug fixes:
868        - fixed a crash which occurs when removing a sampler channel waiting
869          to start instrument loading after another channel
870        - fixed a crash which occurs when removing a sampler channel with
871          instrument loading in progress (bug #113)
872        - fixed termination caused by uncaught exception when adding MIDI
873          instrument with PERSISTENT load mode
874        - fixed possible iterator invalidations when resetting the sampler
875        - fixed memory leaks when issuing the following LSCP commands:
876          GET AUDIO_OUTPUT_DRIVER INFO
877          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
878          GET MIDI_INPUT_DRIVER INFO
879          GET MIDI_INPUT_DRIVER_PARAMETER INFO
880        - fixed possible compilation error when sqlite is not present
881        - fixed orphaned pointers when setting maximum voices limit (bug #118)
882        - fixed crash when changing the audio output device of a sampler
883          channel with loaded instrument and start playing notes
884        - fixed endless loop in Engine::SuspendAll() (bug #120)
885        - fixed a low-level atomic load function that was broken on 64-bit
886          PowerPC, which probably could cause crashes on that platform
887        - fixed a memory management error which could cause a crash when a
888          plugin was unloaded
889        - bugfix: two private structs had the same name, which could cause
890          problems if the linker chose the wrong constructor
891        - fixed low-level ConditionServer usage bug that caused lockups on
892          Windows
893    
894    
895    Version 0.5.1 (6 December 2007)
896    
897      * packaging changes:
898        - added autoconf checks for pthread library
899        - added autoconf check for pthread bug found on certain NPTL-enabled
900          glibc versions (see Gentoo bug report #194076)
901        - added autoconf checks for MS Windows
902    
903      * general changes:
904        - bugfix: the thread used by an editor plugin didn't die when the
905          editor closed
906        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
907          out all the space. operator--() did not apply size_mask after
908          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
909          order to avoid problems with the _NonVolatileReader functions.
910        - bugfix: Stream.h: added a missing divide by BytesPerSample in
911          GetWriteSpace(). Since this function is currently only used in
912          the stream's qsort() compare function, it didn't trigger any
913          bugs.
914        - Resampler.h, Synthesizer.h: cubic interpolation now works in
915          24bit mode too. Faster method to read 24bit words on little
916          endian machines (x86): replaced 3 byte reads + shifts with a 1
917          unaligned 32bit read and shift
918        - experimental support for MS Windows (MIDI input via MME, AUDIO
919          output via ASIO)
920        - made handling of SIGINT signal (Ctrl-C) a bit more robust
921        - support for monitoring the total number of active disk streams
922          (new LSCP commands: GET TOTAL_STREAM_COUNT,
923          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
924    
925      * AUDIO driver:
926        - added Windows ASIO low latency audio driver
927    
928      * MIDI driver:
929        - added MME Windows MIDI driver
930    
931      * LSCP server:
932        - added support for Windows style path / filenames, however with
933          forward slash path separators instead of backslash
934          (i.e. "C:/foo/bar.gig")
935        - allow naughty liblscp to send non-string device parameters within
936          apostrophes as well
937        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
938          "LIST FILE INSTRUMENTS <file>" and
939          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
940          about an arbitrary instrument file on the system where the sampler is
941          running on
