* NKSP: Fixed crash when using built-in script array variable "%ALL_EVENTS".
* NKSP: Added built-in function "change_amp_lfo_depth()".
* NKSP: Added built-in function "change_amp_lfo_freq()".
* NKSP: Added built-in function "change_pitch_lfo_depth()".
* NKSP: Added built-in function "change_pitch_lfo_freq()".
* Bumped version (2.0.0.svn44).

1 Version SVN trunk (?)
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.
11 * Gigasampler format engine:
12 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13 cutoff settings.
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
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.
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()".
151 * Instruments DB:
152 - Fixed memory access bug of general DB access code which lead to
153 undefined behavior.
154 - Cleanup of instruments DB file creation and opening code.
155 - The instrument DB path of linuxsampler's --create-instruments-db argument
156 is now optional, if it is missing, then a default location is used.
157 - Added support for scanning SFZ (.sfz) files.
158 - Added support for scanning Sound Font (.sf2) files.
159 - Fixed undefined DB transaction behavior.

180 - lsatomic.h: use gcc provided atomic functions if building with
181 gcc 4.7 and C++11
182 - modernized configure script
183 - fixed linkage error when building with
184 LDFLAGS="-Wl,--no-undefined" (#190)

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

646 - Pass/preserve polyphonic variable data from respective "note" event
647 handler to "release" event handler.

654 channel to a different engine type
655 - fixed crash when deleting a sampler channel or changing engine
656 type while an instrument load was in progress
657 - bugfix: playing a note while changing the instrument could cause
658 a crash, or give "Handing back unknown region" error messages
659 - bugfix: calling SET VOICES (which Fantasia does on start and
660 refresh) could cause instruments to be unloaded
661 - Mac OS X: fixed name collision of enum in EffectControl and
662 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
663 - Mac OS X: fixed hanging threads

665 it caused hanging threads on Windows
666 - Fixed possible crashes due to corrupted MIDI/audio device list
667 after MIDI/audio device creation failure
668 - When creating MIDI instrument map entries with "PERSISTENT" type, the
669 instruments were uselessly precached with zero samples, however it still
670 took the full preloading time and on 1st program change the respective
671 instrument was completely reloaded again.
672 - fixed handling of rapid bank select and program change messages
673 sent to the same sampler channel (patch from the Open Octave
674 project, slightly adjusted)

693 crashes and noise on such transitions).
694 - ignore missing LADSPA paths without ignoring valid LADSPA paths
695 (fixes #208)
696 - Fixed bug in LSCP grammar definition which caused a statement like
697 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
698 practically irrelevant, however it caused problems with the new LSCP
699 shell's auto completion feature).
700 - Fixed MIDI program change messages being ignored if quickly executed
701 after each other (fixes #231).
703 Version 1.0.0 (31 July 2009)
705 * packaging changes:

718 directory of liblinuxsampler dll (look in the same directory and one
719 directory above)
720 - configure script fix: removed unconditional use of SSE
721 - fixed building with sqlite installed in a non-standard directory
722 - when cross-compiling, don't try to create instruments.db
723 - fix for new mingw-w64 version, which has usleep
725 * general changes:
726 - bugfix: on some POSIX systems instrument editor plugins refused to
727 load as we used a non-portable Linux specific struct field

729 - fixed endless loop which occured when loading an instrument editor
730 plugin DLL on Windows systems failed
731 - fixed memory leaks that occurred when liblinuxsampler was unloaded
732 - optimized the SynchronizedConfig class so it doesn't wait
733 unnecessarily long after an update

735 events (e.g. to highlight the pressed keys on the virtual keyboard
736 of gigedit)
737 - added support for triggering notes by instrument editors (see above)
738 - be verbose on DLL load errors (on Linux)
739 - fixed di-harmonic triangle LFO implementation (this LFO implementation

748 multi-core and multi-cpu systems
749 - maximum voices and disk streams can now be altered at runtime
750 - fixed CPU feature detection on x86_64 (maybe fixes #108)
751 - automatic stacktrace mechanism is now turned off by default and can
752 be switched on by command line option "--stacktrace" (the automatic
753 stacktrace mechanism seems to be broken on most systems at the moment)
754 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
755 a pointer to the launched InstrumentEditor object
756 - added optional 3rd party user data parameter for following
757 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
758 InstrumentEditor::Launch(),
759 InstrumentManager::LaunchInstrumentEditor()
760 - theoretical fix: made SynchronizedConfig follow C++0x memory
761 model more strictly
762 - fixes for using large audio device buffers
763 - Windows: add the installation directory to the DLL search path
764 when loading an editor plugin (solves problems with VST and
765 gigedit on systems with other GTK versions installed)
766 - updated linuxsampler man page
768 * audio driver:
769 - removed the nonsense audio channel constraint (which was hard coded to
770 max. 100 audio channels) for most audio drivers
771 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
772 opposed to the LSCP specs
773 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
774 reflected the wrong value
775 - fixed a memory management bug in ASIO driver
776 - Makefile fix: JACK_CFLAGS wasn't used
777 - JACK: use jack_client_open instead of the deprecated
778 jack_client_new

789 energyXT)
790 - VST: changed number of output channels from one stereo to 16
791 stereo
792 - added channel routing, fxsends and midi maps to the settings
793 stored in the plugin state
794 - performance optimization of AudioChannel::MixTo() and
795 AudioChannel::CopyTo() methods using GCC vector exensions
796 (if available)
797 - ASIO fixes: avoid initializing the device twice, avoid throwing
798 exception when getting parameters from a disconnected device
800 * MIDI driver:
801 - added JACK MIDI driver
802 - dispatch bank select as ordinary CC as well, the user might seriously
803 want to (mis)use it for some purpose ("fixed" in all current MIDI
804 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
805 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
806 CoreMidi or AU
807 - fixed mingw-w64 compilation error in MME driver
808 - made program change handling in MIDI thread real-time safe by
809 moving the logic to a non-RT thread
810 - fixed minor memory leak in ALSA driver
812 * instruments database:
813 - avoid time consuming samples scanning when adding instruments

820 instrument database compilable
821 - added instrument database support on Windows
822 works with both standalone mode and VST plugin.
823 the instruments DB file is located in
824 %USERPROFILE%\.linuxsampler\instruments.db which allows different
825 databases for each windows user
826 if no DB is present it automatically creates the .linuxsampler subdir
827 and then creates an empty DB
828 - fixed recursive import, which was broken on Windows
830 * Gigasampler format engine:
831 - fixed a memory leak that could happen when a channel was deleted
832 while notes were playing
833 - made it possible to load an instrument even if the audio thread
834 isn't running
835 - added partial support for the "Controller Triggered" MIDI rule,
836 enough for piano gigs with pedal noise samples
837 - minor fix: only mark FX sends as being modified if really the
838 respective FX send MIDI controller was used
839 - added support for GM global device volume SysEx message
840 (can be selected at compile time to either apply globally to the
841 whole sampler [default] or only to the sampler channels that are
842 connected to the respective MIDI input port the SysEx message arrived
843 on)
844 - bugfix: notes triggered at position 0 in the audio buffer were
845 sometimes wrongly killed in the same buffer, causing no sound to
846 be played
847 - added support for chromatic / drumkit mode Roland GS Sysex message
848 which is usally used to switch a part between chromatic sounds and
849 drumkit sounds (as opposed to their common default setting of MIDI
850 part 10 being a drumkit part and all other ones chromatic parts), in
851 LS however one can switch between the first 16 MIDI instrument maps
852 defined for the sampler
853 - made it possible to create multiple sample channels even if the
854 audio thread isn't running
855 - fixed crash when removing channel with active voices (#116)
856 - bugfix: on sample reference changes (instrument editor), only
857 un-cache the respective sample if it's really not used by any
858 sampler engine anymore
859 - re-cache samples in case they were changed by an instrument editor,
860 e.g. when a sample was added while playing (#82)
861 - fixed hanging notes which occured when note-off event had the exact
862 same time stamp as the voice's note-on event and occured both in the
863 same audio fragment cycle (fixes bug #112)
864 - added support for the "fine tune" and "pitch bend range"
865 instrument-level gig parameters
866 - fixed minor artifacts in pitch bend handling
867 - added support for GS Reset SysEx message
868 - allow gig files to use unlimited downward pitch shifting
869 - added a limit check for upward pitch shifting
870 - bugfix: sometimes, when playing a note twice fast, the second
871 note was silent
872 - fixed crash happening when a pitch bend event arrived at the
873 same time a new instrument was loading
875 * LSCP server:
876 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
877 react on MIDI data arriving on certain sampler channels (so far only
878 Note-On and Note-Off events are sent via this LSCP event)
879 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
880 react on MIDI data arriving on certain MIDI input devices (so far only
881 Note-On and Note-Off events are sent via this LSCP event)
882 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
884 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
885 frontends to send MIDI messages to specific sampler channel
886 - added two additional fields to GET FILE INSTRUMENT INFO command -
888 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
889 was incorrect
890 - Optimized the retrieval of the MIDI instrument mappings
891 - added new LSCP command "SET VOICES" to globally alter the maximum
892 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
893 be triggered respectively
894 - added new LSCP command "SET STREAMS" to globally alter the maximum
895 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
896 which will be triggered respectively
897 - bugfix: retry if "select" returns EINTR (this fixes a crash when
898 a gigedit file dialog is opened)
899 - close all connections when LSCPServer is deleted
900 - hard close of all sockets on exit
901 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
902 driver
904 * Bug fixes:
905 - fixed a crash which occurs when removing a sampler channel waiting
906 to start instrument loading after another channel
907 - fixed a crash which occurs when removing a sampler channel with
908 instrument loading in progress (bug #113)
909 - fixed termination caused by uncaught exception when adding MIDI
910 instrument with PERSISTENT load mode
911 - fixed possible iterator invalidations when resetting the sampler
912 - fixed memory leaks when issuing the following LSCP commands:
917 - fixed possible compilation error when sqlite is not present
918 - fixed orphaned pointers when setting maximum voices limit (bug #118)
919 - fixed crash when changing the audio output device of a sampler
920 channel with loaded instrument and start playing notes
921 - fixed endless loop in Engine::SuspendAll() (bug #120)
922 - fixed a low-level atomic load function that was broken on 64-bit
923 PowerPC, which probably could cause crashes on that platform
924 - fixed a memory management error which could cause a crash when a
925 plugin was unloaded
926 - bugfix: two private structs had the same name, which could cause
927 problems if the linker chose the wrong constructor
928 - fixed low-level ConditionServer usage bug that caused lockups on
929 Windows
932 Version 0.5.1 (6 December 2007)
934 * packaging changes:
935 - added autoconf checks for pthread library
936 - added autoconf check for pthread bug found on certain NPTL-enabled
937 glibc versions (see Gentoo bug report #194076)
938 - added autoconf checks for MS Windows
940 * general changes:
941 - bugfix: the thread used by an editor plugin didn't die when the
942 editor closed
943 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
944 out all the space. operator--() did not apply size_mask after
945 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
946 order to avoid problems with the _NonVolatileReader functions.
947 - bugfix: Stream.h: added a missing divide by BytesPerSample in
948 GetWriteSpace(). Since this function is currently only used in
949 the stream's qsort() compare function, it didn't trigger any
950 bugs.
951 - Resampler.h, Synthesizer.h: cubic interpolation now works in
952 24bit mode too. Faster method to read 24bit words on little
953 endian machines (x86): replaced 3 byte reads + shifts with a 1
954 unaligned 32bit read and shift
955 - experimental support for MS Windows (MIDI input via MME, AUDIO
956 output via ASIO)
957 - made handling of SIGINT signal (Ctrl-C) a bit more robust
958 - support for monitoring the total number of active disk streams
959 (new LSCP commands: GET TOTAL_STREAM_COUNT,
962 * AUDIO driver:
963 - added Windows ASIO low latency audio driver
965 * MIDI driver:
966 - added MME Windows MIDI driver
968 * LSCP server:
969 - added support for Windows style path / filenames, however with
970 forward slash path separators instead of backslash
971 (i.e. "C:/foo/bar.gig")
972 - allow naughty liblscp to send non-string device parameters within
973 apostrophes as well
974 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
975 "LIST FILE INSTRUMENTS <file>" and
976 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
977 about an arbitrary instrument file on the system where the sampler is
978 running on
980 Version 0.5.0 (15 October 2007)
982 * packaging changes:
983 - config.h is not going to be installed along with liblinuxsampler's
984 API header files anymore
985 - only the API relevant header (and source) files will be exported to
986 the Doxygen API documentation (explicitly listed in Doxyfile.in)
987 - added completely new XCode project files for Mac OSX which is now
988 capable to execute our autoconf environment, thus no need anymore
989 to maintain the compile time configuration file (osx/version.h) for
990 OSX manually (patch by Toshi Nagata)
991 - fixed buggy boolean --enable-foo / --disable-foo configure script
992 parameters
993 - global.h now only covers global definitions that are needed for the
994 C++ API header files, all implementation internal global definitions
995 are now in global_private.h
996 - atomic.h is not exposed to the C++ API anymore
997 - no need to include config.h anymore for using LS's API header files
998 - fixed warnings in API doc generation
1000 * general changes:
1001 - replaced the old, confusing MIDI program change mechanism by a
1002 flexible MIDI instrument mapper which allows to map arbitrary
1003 (MIDI bank, MIDI program) pairs with arbitrary
1004 (engine type, instrument file, file index) triplets which will be
1005 loaded on the respective channel when such MIDI program change
1006 messages arrive, beside that, each entry allows to define a life-time
1007 strategy for the instrument, so the user can define whether the
1008 instrument should i.e. be permanently loaded (to be able to switch
1009 quickly among sounds) or i.e. loaded just on demand when the
1010 respective program change arrives (to safe RAM space), as well as a
1011 global volume factor for each entry, so the user can adjust the volume
1012 dynamic of his mapped instrument collection without having to modify
1013 the instrument files, also one can manage arbitrary amount of such
1014 MIDI instrument maps and assign each sampler channel individually
1015 a certain map, so that i.e. separation of normal instruments and
1016 drumkits is possible
1017 - new notification events for tracking changes to audio/MIDI devices,
1018 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1019 - sampler was limited to load max. 200 instruments in the background
1020 due to a constant size RingBuffer FIFO which is now replaced by a
1021 dynamic (unlimited) size std::list FIFO
1022 - added FX sends, these allow to route audio signals to arbitrary audio
1023 output channels for being processed by external effect processors
1024 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1025 controllers
1026 - global (sampler wide) volume can now be controlled at runtime
1027 - Implemented new, improved notification system
1028 - fixed compilation errors regarding OSX
1029 (patch by Toshi Nagata)
1030 - implemented instruments database
1031 - added support for escape sequences to the instruments database
1032 - added highly experimental support for on-the-fly instrument editing
1033 within the sampler's process (by using instrument editor plugins),
1034 you'll notice the new "Registered instrument editors:" message on
1035 startup, added a new LSCP command:
1036 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1037 to spawn a matching instrument editor for the instrument on the
1038 given sampler channel, the plugin path can be overridden at compile
1039 time with ./configure --enable-plugin-dir=/some/dir
1040 - added experimental code for synchronizing instrument editors hosted
1041 in the sampler's process to safely edit instruments while playing
1042 without a crash (hopefully) by either suspending single regions
1043 wherever possible or if unavoidable whole engine(s)
1044 - fixed several issues in fundamental "Thread" class: set scheduling
1045 policy and priority on thread level, set a minimum stack size for
1046 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1047 threads simply inherited properties of starting thread instead of
1048 setting their own policy and priority
1049 - minor fix in our automatic stack trace mechanism on crashes, the
1050 main process did not wait for the stack trace process to finish
1051 its output
1052 - fixed some minor memory leaks
1053 - reenabled assembly features support, at the moment only for
1054 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1055 - minor assembly fix in x86 features detection (don't use the PIC
1056 register, to avoid relocations in the text segment at runtime)
1057 - POSIX callback functions of Thread.h are hidden
1059 * MIDI driver:
1060 - dispatch bank select (MSB and LSB) messages
1062 * audio driver:
1063 - the ALSA audio output driver parameters now reflect the correct
1064 parameter value ranges for the respective selected sound card
1065 (patch by Till Wimmer, a bit fixed and extended)
1067 * Gigasampler format engine:
1068 - if a filter is used and EG2 finishes before EG1, let the voice
1069 die when EG2 has finished (this fixes a problem with clicks and
1070 voice starvation for some gigs)
1071 - playback is no longer disabled during instrument loading
1072 - all notes playing on a channel that changes its instrument keep
1073 playing with the old instrument until they get a note off
1074 command
1075 - EG fix: a release value of zero could cause noises or crash
1076 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1077 - EG fine tuning: when attack is zero the EG starts at a level
1078 above max sustain level, which means that there is a decay phase
1079 even if sustain is 100%
1080 - more EG fixes: the level could sometimes go below zero and cause
1081 noises or crashes
1082 - minor fix of EGDecay (patch by Toshi Nagata)
1083 - fixed compiler error when --enable-override-filter-type was
1084 supplied to the configure script (fixes #46)
1085 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1086 instead of a fix value
1087 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1088 127 (solo mode) only kill voices if the respective mode really
1089 changed
1091 * LSCP server:
1092 - fixed compile time error for old Bison versions
1093 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1094 - parser now supports extended ASCII character set
1095 (up to ASCII code 255, i.e. includes now umlauts and accents)
1096 - filename arguments in LSCP commands now allow to use escape
1097 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1098 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1099 code value like \xf2) (fixes bug #24)
1100 - the following LSCP commands now also support escape sequences for at
1101 least one of their text-based parameters (i.e. name, description):
1108 - returns verbose syntax errors (line and column where syntax error
1109 occured, the unexpected character and the actually expected, possible
1110 character(s), the latter only if less than 5 possibilities)
1111 - made sure that LSCP syntax is not affected by gigedit locale
1112 settings
1113 - bugfix regarding strings parameter lists: all comma separated lists
1114 of strings were treated as being one string containing commas
1115 (fixes #57)
1117 * Bug fixes:
1118 - fixed crash occurring on certain LSCP scripts (Bug 39)
1119 - another thread safety fix for lscp "load engine" and "set
1120 channel audio output device"
1121 - fixed a crash which occurs when reassigning the same engine
1122 on a sampler channel with connected MIDI device
1123 - fixed a crash which occurs when changing the number of ports of a MIDI
1124 device connected to a sampler channel to number less then or equal
1125 to the index of the port to which the sampler channel is connected.
1126 - The previous bindings were not been disconnected when altering
1127 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1128 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1129 - The active stream/voice count statistic was incorrect.
1130 - notification events were not been sent for some sampler
1131 channel changes
1132 - added default min and max values to restrict the number of allowed
1133 audio output channels and MIDI input ports
1134 - the connection to the PCM interface is now closed when destroying
1135 an audio output device
1136 - files with slash in their path or filename could not be loaded
1138 * test cases:
1139 - updated and fixed (haven't been touched in a while)
1141 Version 0.4.0 (24 November 2006)
1143 * packaging changes:
1144 - changed deprecated copyright attribute to license; added ldconfig
1145 to post-(un)install steps; added devel package for liblinuxsampler;
1146 to linuxsampler.spec (RPM)
1147 - install necessary development header files for allowing 3rd party
1148 applications to link against liblinuxsampler
1149 - liblinuxsampler's API documentation can be generated with 'make docs'
1150 (Doxygen required)
1151 - added benchmark to automatically detect the best triangle LFO
1152 implementation (currently either an integer math solution or a
1153 di-harmonic approximation), automatic detection can be overriden
1154 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1155 configure script argument though (mandatory for cross-compilation)
1156 - do not automatically pick optimized gcc flags if the user already
1157 provided some on his own (as CXXFLAGS)
1158 - added compile time option to disable processing of All-Notes-Off MIDI
1159 messages
1160 - added compile time options to allow disabling the various audio and
1161 MIDI drivers
1162 - fixed automatic GCC CPU switch detection on PPC
1163 (patch by Ebrahim Mayat)
1165 * Gigasampler format engine:
1166 - extensive synthesis optimization
1167 (reimplementation of EGs and LFO(s), removed synthesis parameter
1168 prerendering and the synthesis parameter matrix in general, splitting
1169 each audio fragment into subfragments now where each subfragment uses
1170 constant pitch and filter coefficients. The volume coefficient is
1171 linearly interpolated inside a subfragment, unless
1172 --disable-interpolate-volume is set.)
1173 - fine tuning of the EG modulation parameters
1174 - improved filter cutoff calculation by adding support for the
1175 following gig parameters: Cutoff freq (used when no cutoff
1176 controller is defined), Control invert, Minimum cutoff, Velocity
1177 curve and Velocity range. The keyboard tracking now scales
1178 cutoff frequency instead of resonance.
1179 - added support for gig parameter Resonance.
1180 - fixed bug in sysex handling (patch by Juan Linietsky)
1181 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1182 which can be overridden with --enable-global-attenuation
1183 - EG fixes: made the length of "attack hold" stage more
1184 accurate. Release stage can now start before attack stage
1185 ends. Cancel release didn't work when sustain was zero. Attack
1186 time now has a minimal value to prevent clicks.
1187 - fixed pitch changes larger than one octave
1188 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1189 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1190 all modes can be altered via standard GM messages, that is CC5 for
1191 altering portamento time, CC65 for enabling / disabling portamento
1192 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1193 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1194 parameter) and crossfade
1195 - added support for the "attenuation controller threshold" gig
1196 parameter
1197 - added smoothing of volume changes caused by control change
1198 messages
1199 - sample loop parameters are now taken from the DimensionRegion
1200 instead of the wave chunk
1201 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1202 not equal to a power of two
1203 - reimplementation of the filter algorithm. The new filter is more
1204 accurate and supports all gig filter types, including bandreject
1205 and lowpass turbo.
1206 - real support for 24 bit samples - samples are not truncated to
1207 16 bits anymore
1208 - support for aftertouch (channel pressure, not polyphonic
1209 aftertouch)
1210 - LFO1 behaviour fixed (dampening from max volume instead of
1211 amplifying from 0)
1213 * LSCP server:
1214 - fixed application exit on broken pipe error (fixes bug #20)
1215 - fixed the notification messages delay due to lack of
1216 network activity (fixes bug #26)
1217 - fixed parser bug which occured on space(s) within device parameters
1220 * audio driver:
1221 - added aRts audio output driver (by no means RT safe)
1223 * MIDI driver:
1224 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1225 messages several times instead of once
1226 - API extension for MIDI drivers which already supply exact time stamps
1227 for events (i.e. for offline rendering based MIDI drivers)
1228 - added checks for bad MIDI data
1230 * linuxsampler application:
1231 - show available sampler engine types on startup
1233 * general changes:
1234 - support for muting sampler channels and solo mode of the same, two new
1235 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1236 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1237 introduced for this, the behavior is the same like on a mixer console
1238 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1239 --enable-process-muted-channels which can be used to enable the
1240 processing of muted channels.
1241 - support for sostenuto pedal
1242 - support for monitoring the total number of active voices
1245 - fixed some memory management errors
1246 - fixed some concurrency problems that could lead to crashes when
1247 LSCP commands were executed
1248 - fixed crash when instrument loading failed previously on the same
1249 sampler channel (fixes bug #36)
1251 Version 0.3.3 (15 July 2005)
1253 * packaging changes:
1254 - fixed compilation with gcc 4.0
1256 * Gigasampler format engine:
1257 - LFO preprocessing was performed even though the respective LFO was
1258 disabled by the instrument patch (minor efficiency fix)
1259 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1260 for volume ramp downs in the same fragment (needed for current voice
1261 stealing implementation) then simply inform the user with a warning
1262 about possible click sounds and reduce the volume ramp down
1263 appropriately instead of cancelling the audio device connection
1265 Version 0.3.2 (24 June 2005)
1267 * packaging changes:
1268 - updated autotools build files to compile on OS X
1269 (conditional compilation of CoreMIDI and MidiShare drivers)
1270 - hand-crafted assembly optimization code can be disabled with
1271 './configure --disable-asm' (definitely not recommended)
1272 - fixed 'make dist' rule to include all necessary files
1273 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1274 (due to 'dist-bzip2' automake option)
1276 * Gigasampler format engine:
1277 - support for the gig parameters for "release velocity response" curves
1278 - fine tuning of the EGADSR envelope
1279 - volume of release triggered samples now depends on note-on velocity,
1280 note length and gig parameter "release trigger decay" instead of
1281 note-off velocity.
1282 - revised voice stealing
1283 (fixes crash and endless loop caused by voice stealing)
1284 - don't reset scale tuning on instrument or audio output device change
1285 - handle key group conflicts right at the beginning of each fragment
1286 instead of when the respective voice is actually launched
1287 (fixes undefined behavior if stolen voices belonged to a key group -
1288 this case was followed by a "killed voice survived" error message)
1289 - fixed minor issue with null/silence samples
1290 (those stole voices even though they don't need a voice at all which
1291 resulted in "voice stealing didn't work out" messages)
1292 - don't reset volume, pan, pitch and MIDI controller values on
1293 instrument or audio output device change
1295 * LSCP server:
1296 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1297 - fixed LSCP event "CHANNEL_INFO" notification
1298 (e.g. did not notify on volume changes or MIDI program change events)
1300 * linuxsampler application:
1301 - added command line parameters --lscp-addr and --lscp-port to override
1302 default IP address and port of LSCP server
1304 Version 0.3.1 (24 May 2005)
1306 * initial release
