* NKSP Fix: "init" event handler was not always executed when a script
  was loaded.
* NKSP built-in wait() script function: abort script execution if
  a negative or zero wait time was passed as argument (since this is
  a common indication of a bug either of the script or even of the
  engine, which could lead to RT instability or even worse).
* Bumped version (2.0.0.svn24).

1 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

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

274 - fixed crash when using sw_down/up
275 - improved logic for sw_lokey/hikey/up/down/last
276 - added more v1 aliases to parser
277 - reduced memory usage for sfz data
278 - RT-safeness: avoid malloc in audio thread
279 - fixed a bug that could cause voice stealing to fail
280 - optimized sample lookup
281 - improved support for exclusive groups (group, off_by and
282 off_mode)
283 - added support for controller triggered regions (on_locc/on_hicc)
284 - added support for loop_mode=one_shot
285 - fixed playback of 16 bit wav files on big endian CPUs
286 - added support for Ogg Vorbis sample files
287 - use loop markers from sample file if loop_start and loop_end are
288 not set in sfz file
289 - implemeted filters. Filter types: lowpass, bandpass, bandreject
290 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
291 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
292 cutoff_cc, cutoff_chanaft.
293 - bugfix: zero ampeg_sustain didn't work

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

446 loaded a second time (this time it's for Linux and Mac, previous
447 similar fix was for Windows)
448 - thread safety fixes for the instrument loading thread

482 the driver will automatically connect to other CoreMIDI clients' ports
483 (e.g. external MIDI devices being attached to the Mac)
484 - added support for MIDI note on velocity filter
485 - CoreMIDI: fixed memory deallocation error
486 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
487 virtual keyboards in frontends / instrument editors being stuck.
488 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

615 channel to a different engine type
616 - fixed crash when deleting a sampler channel or changing engine
617 type while an instrument load was in progress
618 - bugfix: playing a note while changing the instrument could cause
619 a crash, or give "Handing back unknown region" error messages
620 - bugfix: calling SET VOICES (which Fantasia does on start and
621 refresh) could cause instruments to be unloaded
622 - Mac OS X: fixed name collision of enum in EffectControl and
623 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
624 - Mac OS X: fixed hanging threads
625 - Windows: disabled the previous thread fix on non-Mac systems, as
626 it caused hanging threads on Windows
627 - Fixed possible crashes due to corrupted MIDI/audio device list
628 after MIDI/audio device creation failure
629 - When creating MIDI instrument map entries with "PERSISTENT" type, the
630 instruments were uselessly precached with zero samples, however it still
631 took the full preloading time and on 1st program change the respective
632 instrument was completely reloaded again.
633 - fixed handling of rapid bank select and program change messages
634 sent to the same sampler channel (patch from the Open Octave
635 project, slightly adjusted)

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

669 "./configure --disable-jack-driver" was used
670 (patch by Alexis Ballier)
671 - fixed compilation with gcc 4.3
672 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

679 directory of liblinuxsampler dll (look in the same directory and one
680 directory above)
681 - configure script fix: removed unconditional use of SSE
682 - fixed building with sqlite installed in a non-standard directory
683 - when cross-compiling, don't try to create instruments.db
684 - fix for new mingw-w64 version, which has usleep
685
686 * general changes:
687 - bugfix: on some POSIX systems instrument editor plugins refused to
688 load as we used a non-portable Linux specific struct field
689 (fixes bug #70, patch by Ronald Baljeu)
690 - fixed endless loop which occured when loading an instrument editor
691 plugin DLL on Windows systems failed
692 - fixed memory leaks that occurred when liblinuxsampler was unloaded
693 - optimized the SynchronizedConfig class so it doesn't wait
694 unnecessarily long after an update
695 - added support for notifying instrument editors on note-on / note-off
696 events (e.g. to highlight the pressed keys on the virtual keyboard
697 of gigedit)
698 - added support for triggering notes by instrument editors (see above)
699 - be verbose on DLL load errors (on Linux)
700 - fixed di-harmonic triangle LFO implementation (this LFO implementation
701 is only used by very few systems, most pick the int math
702 implementation, which is usually faster)
703 - fixes for audio drivers with varying buffer sizes
704 - experimental support for running LinuxSampler as a DSSI, LV2 and
705 VST plugin
706 - notification events for stream/voice count statistics are now sent
707 only when there are actual changes
708 - added memory ordering constraints to improve stability on
709 multi-core and multi-cpu systems
710 - maximum voices and disk streams can now be altered at runtime
711 - fixed CPU feature detection on x86_64 (maybe fixes #108)
712 - automatic stacktrace mechanism is now turned off by default and can
713 be switched on by command line option "--stacktrace" (the automatic
714 stacktrace mechanism seems to be broken on most systems at the moment)
715 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
716 a pointer to the launched InstrumentEditor object
717 - added optional 3rd party user data parameter for following
718 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
719 InstrumentEditor::Launch(),
720 InstrumentManager::LaunchInstrumentEditor()
721 - theoretical fix: made SynchronizedConfig follow C++0x memory
722 model more strictly
723 - fixes for using large audio device buffers
724 - Windows: add the installation directory to the DLL search path
725 when loading an editor plugin (solves problems with VST and
726 gigedit on systems with other GTK versions installed)
727 - updated linuxsampler man page
728
729 * audio driver:
730 - removed the nonsense audio channel constraint (which was hard coded to
731 max. 100 audio channels) for most audio drivers
732 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
733 opposed to the LSCP specs
734 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
735 reflected the wrong value
736 - fixed a memory management bug in ASIO driver
737 - Makefile fix: JACK_CFLAGS wasn't used
738 - JACK: use jack_client_open instead of the deprecated
739 jack_client_new

745 win64)
746 - VST: added support for sample rate and buffer size changes
747 - VST: close editor (Fantasia) when the VST is removed
748 - VST: avoid opening Fantasia more than once for each VST instance
749 - VST: export main function as "main" on Linux too (fix for
750 energyXT)
751 - VST: changed number of output channels from one stereo to 16
752 stereo
753 - added channel routing, fxsends and midi maps to the settings
754 stored in the plugin state
755 - performance optimization of AudioChannel::MixTo() and
756 AudioChannel::CopyTo() methods using GCC vector exensions
757 (if available)
758 - ASIO fixes: avoid initializing the device twice, avoid throwing
759 exception when getting parameters from a disconnected device
760
761 * MIDI driver:
762 - added JACK MIDI driver
763 - dispatch bank select as ordinary CC as well, the user might seriously
764 want to (mis)use it for some purpose ("fixed" in all current MIDI
765 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
766 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
767 CoreMidi or AU
768 - fixed mingw-w64 compilation error in MME driver
769 - made program change handling in MIDI thread real-time safe by
770 moving the logic to a non-RT thread
771 - fixed minor memory leak in ALSA driver
772
773 * instruments database:
774 - avoid time consuming samples scanning when adding instruments
775 to the instruments database

780 - work-around for missing fnmatch function on Windows to make
781 instrument database compilable
782 - added instrument database support on Windows
783 works with both standalone mode and VST plugin.
784 the instruments DB file is located in
785 %USERPROFILE%\.linuxsampler\instruments.db which allows different
786 databases for each windows user
787 if no DB is present it automatically creates the .linuxsampler subdir
788 and then creates an empty DB
789 - fixed recursive import, which was broken on Windows
790
791 * Gigasampler format engine:
792 - fixed a memory leak that could happen when a channel was deleted
793 while notes were playing
794 - made it possible to load an instrument even if the audio thread
795 isn't running
796 - added partial support for the "Controller Triggered" MIDI rule,
797 enough for piano gigs with pedal noise samples
798 - minor fix: only mark FX sends as being modified if really the
799 respective FX send MIDI controller was used
800 - added support for GM global device volume SysEx message
801 (can be selected at compile time to either apply globally to the
802 whole sampler [default] or only to the sampler channels that are
803 connected to the respective MIDI input port the SysEx message arrived
804 on)
805 - bugfix: notes triggered at position 0 in the audio buffer were
806 sometimes wrongly killed in the same buffer, causing no sound to
807 be played
808 - added support for chromatic / drumkit mode Roland GS Sysex message
809 which is usally used to switch a part between chromatic sounds and
810 drumkit sounds (as opposed to their common default setting of MIDI
811 part 10 being a drumkit part and all other ones chromatic parts), in
812 LS however one can switch between the first 16 MIDI instrument maps
813 defined for the sampler
814 - made it possible to create multiple sample channels even if the
815 audio thread isn't running
816 - fixed crash when removing channel with active voices (#116)
817 - bugfix: on sample reference changes (instrument editor), only
818 un-cache the respective sample if it's really not used by any
819 sampler engine anymore
820 - re-cache samples in case they were changed by an instrument editor,
821 e.g. when a sample was added while playing (#82)
822 - fixed hanging notes which occured when note-off event had the exact
823 same time stamp as the voice's note-on event and occured both in the
824 same audio fragment cycle (fixes bug #112)
825 - added support for the "fine tune" and "pitch bend range"
826 instrument-level gig parameters
827 - fixed minor artifacts in pitch bend handling
828 - added support for GS Reset SysEx message
829 - allow gig files to use unlimited downward pitch shifting
830 - added a limit check for upward pitch shifting
831 - bugfix: sometimes, when playing a note twice fast, the second
832 note was silent
833 - fixed crash happening when a pitch bend event arrived at the
834 same time a new instrument was loading
835
836 * LSCP server:
837 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
838 react on MIDI data arriving on certain sampler channels (so far only
839 Note-On and Note-Off events are sent via this LSCP event)
840 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
841 react on MIDI data arriving on certain MIDI input devices (so far only
842 Note-On and Note-Off events are sent via this LSCP event)
843 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
844 SET DB_INSTRUMENT FILE_PATH
845 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
846 frontends to send MIDI messages to specific sampler channel
847 - added two additional fields to GET FILE INSTRUMENT INFO command -
848 KEY_BINDINGS and KEYSWITCH_BINDINGS
849 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
850 was incorrect
851 - Optimized the retrieval of the MIDI instrument mappings
852 - added new LSCP command "SET VOICES" to globally alter the maximum
853 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
854 be triggered respectively
855 - added new LSCP command "SET STREAMS" to globally alter the maximum
856 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
857 which will be triggered respectively
858 - bugfix: retry if "select" returns EINTR (this fixes a crash when
859 a gigedit file dialog is opened)
860 - close all connections when LSCPServer is deleted
861 - hard close of all sockets on exit
862 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
863 driver
864
865 * Bug fixes:
866 - fixed a crash which occurs when removing a sampler channel waiting
867 to start instrument loading after another channel
868 - fixed a crash which occurs when removing a sampler channel with
869 instrument loading in progress (bug #113)
870 - fixed termination caused by uncaught exception when adding MIDI
871 instrument with PERSISTENT load mode
872 - fixed possible iterator invalidations when resetting the sampler
873 - fixed memory leaks when issuing the following LSCP commands:
874 GET AUDIO_OUTPUT_DRIVER INFO
875 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
876 GET MIDI_INPUT_DRIVER INFO
877 GET MIDI_INPUT_DRIVER_PARAMETER INFO
878 - fixed possible compilation error when sqlite is not present
879 - fixed orphaned pointers when setting maximum voices limit (bug #118)
880 - fixed crash when changing the audio output device of a sampler
881 channel with loaded instrument and start playing notes
882 - fixed endless loop in Engine::SuspendAll() (bug #120)
883 - fixed a low-level atomic load function that was broken on 64-bit
884 PowerPC, which probably could cause crashes on that platform
885 - fixed a memory management error which could cause a crash when a
886 plugin was unloaded
887 - bugfix: two private structs had the same name, which could cause
888 problems if the linker chose the wrong constructor
889 - fixed low-level ConditionServer usage bug that caused lockups on
890 Windows
891
892
893 Version 0.5.1 (6 December 2007)
894
895 * packaging changes:
896 - added autoconf checks for pthread library
897 - added autoconf check for pthread bug found on certain NPTL-enabled
898 glibc versions (see Gentoo bug report #194076)
899 - added autoconf checks for MS Windows
900
901 * general changes:
902 - bugfix: the thread used by an editor plugin didn't die when the
903 editor closed
904 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
905 out all the space. operator--() did not apply size_mask after
906 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
907 order to avoid problems with the _NonVolatileReader functions.
908 - bugfix: Stream.h: added a missing divide by BytesPerSample in
909 GetWriteSpace(). Since this function is currently only used in
910 the stream's qsort() compare function, it didn't trigger any
911 bugs.
912 - Resampler.h, Synthesizer.h: cubic interpolation now works in
913 24bit mode too. Faster method to read 24bit words on little
914 endian machines (x86): replaced 3 byte reads + shifts with a 1
915 unaligned 32bit read and shift
916 - experimental support for MS Windows (MIDI input via MME, AUDIO
917 output via ASIO)
918 - made handling of SIGINT signal (Ctrl-C) a bit more robust
919 - support for monitoring the total number of active disk streams
920 (new LSCP commands: GET TOTAL_STREAM_COUNT,
921 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
922
923 * AUDIO driver:
924 - added Windows ASIO low latency audio driver
925
926 * MIDI driver:
927 - added MME Windows MIDI driver
928
929 * LSCP server:
930 - added support for Windows style path / filenames, however with
931 forward slash path separators instead of backslash
932 (i.e. "C:/foo/bar.gig")
933 - allow naughty liblscp to send non-string device parameters within
934 apostrophes as well
935 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
936 "LIST FILE INSTRUMENTS <file>" and
937 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
938 about an arbitrary instrument file on the system where the sampler is
939 running on
940
941 Version 0.5.0 (15 October 2007)
942
943 * packaging changes:
944 - config.h is not going to be installed along with liblinuxsampler's
945 API header files anymore
946 - only the API relevant header (and source) files will be exported to
947 the Doxygen API documentation (explicitly listed in Doxyfile.in)
948 - added completely new XCode project files for Mac OSX which is now
949 capable to execute our autoconf environment, thus no need anymore
950 to maintain the compile time configuration file (osx/version.h) for
951 OSX manually (patch by Toshi Nagata)
952 - fixed buggy boolean --enable-foo / --disable-foo configure script
953 parameters
954 - global.h now only covers global definitions that are needed for the
955 C++ API header files, all implementation internal global definitions
956 are now in global_private.h
957 - atomic.h is not exposed to the C++ API anymore
958 - no need to include config.h anymore for using LS's API header files
959 - fixed warnings in API doc generation
960
961 * general changes:
962 - replaced the old, confusing MIDI program change mechanism by a
963 flexible MIDI instrument mapper which allows to map arbitrary
964 (MIDI bank, MIDI program) pairs with arbitrary
965 (engine type, instrument file, file index) triplets which will be
966 loaded on the respective channel when such MIDI program change
967 messages arrive, beside that, each entry allows to define a life-time
968 strategy for the instrument, so the user can define whether the
969 instrument should i.e. be permanently loaded (to be able to switch
970 quickly among sounds) or i.e. loaded just on demand when the
971 respective program change arrives (to safe RAM space), as well as a
972 global volume factor for each entry, so the user can adjust the volume
973 dynamic of his mapped instrument collection without having to modify
974 the instrument files, also one can manage arbitrary amount of such
975 MIDI instrument maps and assign each sampler channel individually
976 a certain map, so that i.e. separation of normal instruments and
977 drumkits is possible
978 - new notification events for tracking changes to audio/MIDI devices,
979 MIDI instrument maps, MIDI instruments, FX sends, global volume.
980 - sampler was limited to load max. 200 instruments in the background
981 due to a constant size RingBuffer FIFO which is now replaced by a
982 dynamic (unlimited) size std::list FIFO
983 - added FX sends, these allow to route audio signals to arbitrary audio
984 output channels for being processed by external effect processors
985 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
986 controllers
987 - global (sampler wide) volume can now be controlled at runtime
988 - Implemented new, improved notification system
989 - fixed compilation errors regarding OSX
990 (patch by Toshi Nagata)
991 - implemented instruments database
992 - added support for escape sequences to the instruments database
993 - added highly experimental support for on-the-fly instrument editing
994 within the sampler's process (by using instrument editor plugins),
995 you'll notice the new "Registered instrument editors:" message on
996 startup, added a new LSCP command:
997 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
998 to spawn a matching instrument editor for the instrument on the
999 given sampler channel, the plugin path can be overridden at compile
1000 time with ./configure --enable-plugin-dir=/some/dir
1001 - added experimental code for synchronizing instrument editors hosted
1002 in the sampler's process to safely edit instruments while playing
1003 without a crash (hopefully) by either suspending single regions
1004 wherever possible or if unavoidable whole engine(s)
1005 - fixed several issues in fundamental "Thread" class: set scheduling
1006 policy and priority on thread level, set a minimum stack size for
1007 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1008 threads simply inherited properties of starting thread instead of
1009 setting their own policy and priority
1010 - minor fix in our automatic stack trace mechanism on crashes, the
1011 main process did not wait for the stack trace process to finish
1012 its output
1013 - fixed some minor memory leaks
1014 - reenabled assembly features support, at the moment only for
1015 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1016 - minor assembly fix in x86 features detection (don't use the PIC
1017 register, to avoid relocations in the text segment at runtime)
1018 - POSIX callback functions of Thread.h are hidden
1019
1020 * MIDI driver:
1021 - dispatch bank select (MSB and LSB) messages
1022
1023 * audio driver:
1024 - the ALSA audio output driver parameters now reflect the correct
1025 parameter value ranges for the respective selected sound card
1026 (patch by Till Wimmer, a bit fixed and extended)
1027
1028 * Gigasampler format engine:
1029 - if a filter is used and EG2 finishes before EG1, let the voice
1030 die when EG2 has finished (this fixes a problem with clicks and
1031 voice starvation for some gigs)
1032 - playback is no longer disabled during instrument loading
1033 - all notes playing on a channel that changes its instrument keep
1034 playing with the old instrument until they get a note off
1035 command
1036 - EG fix: a release value of zero could cause noises or crash
1037 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1038 - EG fine tuning: when attack is zero the EG starts at a level
1039 above max sustain level, which means that there is a decay phase
1040 even if sustain is 100%
1041 - more EG fixes: the level could sometimes go below zero and cause
1042 noises or crashes
1043 - minor fix of EGDecay (patch by Toshi Nagata)
1044 - fixed compiler error when --enable-override-filter-type was
1045 supplied to the configure script (fixes #46)
1046 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1047 instead of a fix value
1048 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1049 127 (solo mode) only kill voices if the respective mode really
1050 changed
1051
1052 * LSCP server:
1053 - fixed compile time error for old Bison versions
1054 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1055 - parser now supports extended ASCII character set
1056 (up to ASCII code 255, i.e. includes now umlauts and accents)
1057 - filename arguments in LSCP commands now allow to use escape
1058 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1059 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1060 code value like \xf2) (fixes bug #24)
1061 - the following LSCP commands now also support escape sequences for at
1062 least one of their text-based parameters (i.e. name, description):
1063 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1064 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1065 "SET DB_INSTRUMENT_DIRECTORY NAME",
1066 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1067 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1068 "FIND DB_INSTRUMENT_DIRECTORIES"
1069 - returns verbose syntax errors (line and column where syntax error
1070 occured, the unexpected character and the actually expected, possible
1071 character(s), the latter only if less than 5 possibilities)
1072 - made sure that LSCP syntax is not affected by gigedit locale
1073 settings
1074 - bugfix regarding strings parameter lists: all comma separated lists
1075 of strings were treated as being one string containing commas
1076 (fixes #57)
1077
1078 * Bug fixes:
1079 - fixed crash occurring on certain LSCP scripts (Bug 39)
1080 - another thread safety fix for lscp "load engine" and "set
1081 channel audio output device"
1082 - fixed a crash which occurs when reassigning the same engine
1083 on a sampler channel with connected MIDI device
1084 - fixed a crash which occurs when changing the number of ports of a MIDI
1085 device connected to a sampler channel to number less then or equal
1086 to the index of the port to which the sampler channel is connected.
1087 - The previous bindings were not been disconnected when altering
1088 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1089 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1090 - The active stream/voice count statistic was incorrect.
1091 - notification events were not been sent for some sampler
1092 channel changes
1093 - added default min and max values to restrict the number of allowed
1094 audio output channels and MIDI input ports
1095 - the connection to the PCM interface is now closed when destroying
1096 an audio output device
1097 - files with slash in their path or filename could not be loaded
1098
1099 * test cases:
1100 - updated and fixed (haven't been touched in a while)
1101
1102 Version 0.4.0 (24 November 2006)
1103
1104 * packaging changes:
1105 - changed deprecated copyright attribute to license; added ldconfig
1106 to post-(un)install steps; added devel package for liblinuxsampler;
1107 to linuxsampler.spec (RPM)
1108 - install necessary development header files for allowing 3rd party
1109 applications to link against liblinuxsampler
1110 - liblinuxsampler's API documentation can be generated with 'make docs'
1111 (Doxygen required)
1112 - added benchmark to automatically detect the best triangle LFO
1113 implementation (currently either an integer math solution or a
1114 di-harmonic approximation), automatic detection can be overriden
1115 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1116 configure script argument though (mandatory for cross-compilation)
1117 - do not automatically pick optimized gcc flags if the user already
1118 provided some on his own (as CXXFLAGS)
1119 - added compile time option to disable processing of All-Notes-Off MIDI
1120 messages
1121 - added compile time options to allow disabling the various audio and
1122 MIDI drivers
1123 - fixed automatic GCC CPU switch detection on PPC
1124 (patch by Ebrahim Mayat)
1125
1126 * Gigasampler format engine:
1127 - extensive synthesis optimization
1128 (reimplementation of EGs and LFO(s), removed synthesis parameter
1129 prerendering and the synthesis parameter matrix in general, splitting
1130 each audio fragment into subfragments now where each subfragment uses
1131 constant pitch and filter coefficients. The volume coefficient is
1132 linearly interpolated inside a subfragment, unless
1133 --disable-interpolate-volume is set.)
1134 - fine tuning of the EG modulation parameters
1135 - improved filter cutoff calculation by adding support for the
1136 following gig parameters: Cutoff freq (used when no cutoff
1137 controller is defined), Control invert, Minimum cutoff, Velocity
1138 curve and Velocity range. The keyboard tracking now scales
1139 cutoff frequency instead of resonance.
1140 - added support for gig parameter Resonance.
1141 - fixed bug in sysex handling (patch by Juan Linietsky)
1142 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1143 which can be overridden with --enable-global-attenuation
1144 - EG fixes: made the length of "attack hold" stage more
1145 accurate. Release stage can now start before attack stage
1146 ends. Cancel release didn't work when sustain was zero. Attack
1147 time now has a minimal value to prevent clicks.
1148 - fixed pitch changes larger than one octave
1149 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1150 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1151 all modes can be altered via standard GM messages, that is CC5 for
1152 altering portamento time, CC65 for enabling / disabling portamento
1153 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1154 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1155 parameter) and crossfade
1156 - added support for the "attenuation controller threshold" gig
1157 parameter
1158 - added smoothing of volume changes caused by control change
1159 messages
1160 - sample loop parameters are now taken from the DimensionRegion
1161 instead of the wave chunk
1162 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1163 not equal to a power of two
1164 - reimplementation of the filter algorithm. The new filter is more
1165 accurate and supports all gig filter types, including bandreject
1166 and lowpass turbo.
1167 - real support for 24 bit samples - samples are not truncated to
1168 16 bits anymore
1169 - support for aftertouch (channel pressure, not polyphonic
1170 aftertouch)
1171 - LFO1 behaviour fixed (dampening from max volume instead of
1172 amplifying from 0)
1173
1174 * LSCP server:
1175 - fixed application exit on broken pipe error (fixes bug #20)
1176 - fixed the notification messages delay due to lack of
1177 network activity (fixes bug #26)
1178 - fixed parser bug which occured on space(s) within device parameters
1179 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1180
1181 * audio driver:
1182 - added aRts audio output driver (by no means RT safe)
1183
1184 * MIDI driver:
1185 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1186 messages several times instead of once
1187 - API extension for MIDI drivers which already supply exact time stamps
1188 for events (i.e. for offline rendering based MIDI drivers)
1189 - added checks for bad MIDI data
1190
1191 * linuxsampler application:
1192 - show available sampler engine types on startup
1193
1194 * general changes:
1195 - support for muting sampler channels and solo mode of the same, two new
1196 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1197 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1198 introduced for this, the behavior is the same like on a mixer console
1199 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1200 --enable-process-muted-channels which can be used to enable the
1201 processing of muted channels.
1202 - support for sostenuto pedal
1203 - support for monitoring the total number of active voices
1204 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1205 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1206 - fixed some memory management errors
1207 - fixed some concurrency problems that could lead to crashes when
1208 LSCP commands were executed
1209 - fixed crash when instrument loading failed previously on the same
1210 sampler channel (fixes bug #36)
1211
1212 Version 0.3.3 (15 July 2005)
1213
1214 * packaging changes:
1215 - fixed compilation with gcc 4.0
1216
1217 * Gigasampler format engine:
1218 - LFO preprocessing was performed even though the respective LFO was
1219 disabled by the instrument patch (minor efficiency fix)
1220 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1221 for volume ramp downs in the same fragment (needed for current voice
1222 stealing implementation) then simply inform the user with a warning
1223 about possible click sounds and reduce the volume ramp down
1224 appropriately instead of cancelling the audio device connection
1225
1226 Version 0.3.2 (24 June 2005)
1227
1228 * packaging changes:
1229 - updated autotools build files to compile on OS X
1230 (conditional compilation of CoreMIDI and MidiShare drivers)
1231 - hand-crafted assembly optimization code can be disabled with
1232 './configure --disable-asm' (definitely not recommended)
1233 - fixed 'make dist' rule to include all necessary files
1234 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1235 (due to 'dist-bzip2' automake option)
1236
1237 * Gigasampler format engine:
1238 - support for the gig parameters for "release velocity response" curves
1239 - fine tuning of the EGADSR envelope
1240 - volume of release triggered samples now depends on note-on velocity,
1241 note length and gig parameter "release trigger decay" instead of
1242 note-off velocity.
1243 - revised voice stealing
1244 (fixes crash and endless loop caused by voice stealing)
1245 - don't reset scale tuning on instrument or audio output device change
1246 - handle key group conflicts right at the beginning of each fragment
1247 instead of when the respective voice is actually launched
1248 (fixes undefined behavior if stolen voices belonged to a key group -
1249 this case was followed by a "killed voice survived" error message)
1250 - fixed minor issue with null/silence samples
1251 (those stole voices even though they don't need a voice at all which
1252 resulted in "voice stealing didn't work out" messages)
1253 - don't reset volume, pan, pitch and MIDI controller values on
1254 instrument or audio output device change
1255
1256 * LSCP server:
1257 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1258 - fixed LSCP event "CHANNEL_INFO" notification
1259 (e.g. did not notify on volume changes or MIDI program change events)
1260
1261 * linuxsampler application:
1262 - added command line parameters --lscp-addr and --lscp-port to override
1263 default IP address and port of LSCP server
1264
1265 Version 0.3.1 (24 May 2005)
1266
1267 * initial release
