File size: 69867 byte(s)
* Instruments DB: Fixed undefined DB transaction behavior.
* Fixed general compiler warnings.
* Bumped version (2.0.0.svn43).

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

179 - fixed linkage error when building with
180 LDFLAGS="-Wl,--no-undefined" (#190)
181 - fixed compilation with Clang 3.2
182 - removed usage of deprecated Automake variable INCLUDES
183 - fixed building with C++11

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

307 - fixed crash when using sw_down/up
308 - improved logic for sw_lokey/hikey/up/down/last
309 - added more v1 aliases to parser
310 - reduced memory usage for sfz data
311 - RT-safeness: avoid malloc in audio thread
312 - fixed a bug that could cause voice stealing to fail
313 - optimized sample lookup
314 - improved support for exclusive groups (group, off_by and
315 off_mode)
316 - added support for controller triggered regions (on_locc/on_hicc)
317 - added support for loop_mode=one_shot
318 - fixed playback of 16 bit wav files on big endian CPUs
319 - added support for Ogg Vorbis sample files
320 - use loop markers from sample file if loop_start and loop_end are
321 not set in sfz file
322 - implemeted filters. Filter types: lowpass, bandpass, bandreject
323 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
324 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
325 cutoff_cc, cutoff_chanaft.
326 - bugfix: zero ampeg_sustain didn't work

463 - Listen to all interfaces on Mac OS X (INADDR_ANY)
464 - VST bugfix: If the host called resume() before and after
465 changing sample rate or block size, the number of channels was
466 incorrectly set to two. This caused silence in Cubase 5.
467 - save engine type (gig, sfz or sf2) in plugin state

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

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

650 channel to a different engine type
651 - fixed crash when deleting a sampler channel or changing engine
652 type while an instrument load was in progress
653 - bugfix: playing a note while changing the instrument could cause
654 a crash, or give "Handing back unknown region" error messages
655 - bugfix: calling SET VOICES (which Fantasia does on start and
656 refresh) could cause instruments to be unloaded
657 - Mac OS X: fixed name collision of enum in EffectControl and
658 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
659 - Mac OS X: fixed hanging threads
660 - Windows: disabled the previous thread fix on non-Mac systems, as
661 it caused hanging threads on Windows
662 - Fixed possible crashes due to corrupted MIDI/audio device list
663 after MIDI/audio device creation failure
664 - When creating MIDI instrument map entries with "PERSISTENT" type, the
665 instruments were uselessly precached with zero samples, however it still
666 took the full preloading time and on 1st program change the respective
667 instrument was completely reloaded again.
668 - fixed handling of rapid bank select and program change messages
669 sent to the same sampler channel (patch from the Open Octave
670 project, slightly adjusted)

685 playing a note in a key group
686 - fixed erroneous error message piping in VoiceBase.h
687 (labelled "Disk stream not available in time")
688 - Update effects on sample rate & period size changes (to avoid
689 crashes and noise on such transitions).
690 - ignore missing LADSPA paths without ignoring valid LADSPA paths
691 (fixes #208)
692 - Fixed bug in LSCP grammar definition which caused a statement like
693 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
694 practically irrelevant, however it caused problems with the new LSCP
695 shell's auto completion feature).
696 - Fixed MIDI program change messages being ignored if quickly executed
697 after each other (fixes #231).
698
699 Version 1.0.0 (31 July 2009)
700
701 * packaging changes:
702 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
703 causing e.g. the libgig test to fail when
704 "./configure --disable-jack-driver" was used
705 (patch by Alexis Ballier)
706 - fixed compilation with gcc 4.3
707 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

712 - minor fix in configure for mmsystem.h detection on MinGW
713 - Windows: look for editor plugins and Fantasia using base
714 directory of liblinuxsampler dll (look in the same directory and one
715 directory above)
716 - configure script fix: removed unconditional use of SSE
717 - fixed building with sqlite installed in a non-standard directory
718 - when cross-compiling, don't try to create instruments.db
719 - fix for new mingw-w64 version, which has usleep
720
721 * general changes:
722 - bugfix: on some POSIX systems instrument editor plugins refused to
723 load as we used a non-portable Linux specific struct field
724 (fixes bug #70, patch by Ronald Baljeu)
725 - fixed endless loop which occured when loading an instrument editor
726 plugin DLL on Windows systems failed
727 - fixed memory leaks that occurred when liblinuxsampler was unloaded
728 - optimized the SynchronizedConfig class so it doesn't wait
729 unnecessarily long after an update
730 - added support for notifying instrument editors on note-on / note-off
731 events (e.g. to highlight the pressed keys on the virtual keyboard
732 of gigedit)
733 - added support for triggering notes by instrument editors (see above)
734 - be verbose on DLL load errors (on Linux)
735 - fixed di-harmonic triangle LFO implementation (this LFO implementation
736 is only used by very few systems, most pick the int math
737 implementation, which is usually faster)
738 - fixes for audio drivers with varying buffer sizes
739 - experimental support for running LinuxSampler as a DSSI, LV2 and
740 VST plugin
741 - notification events for stream/voice count statistics are now sent
742 only when there are actual changes
743 - added memory ordering constraints to improve stability on
744 multi-core and multi-cpu systems
745 - maximum voices and disk streams can now be altered at runtime
746 - fixed CPU feature detection on x86_64 (maybe fixes #108)
747 - automatic stacktrace mechanism is now turned off by default and can
748 be switched on by command line option "--stacktrace" (the automatic
749 stacktrace mechanism seems to be broken on most systems at the moment)
750 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
751 a pointer to the launched InstrumentEditor object
752 - added optional 3rd party user data parameter for following
753 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
754 InstrumentEditor::Launch(),
755 InstrumentManager::LaunchInstrumentEditor()
756 - theoretical fix: made SynchronizedConfig follow C++0x memory
757 model more strictly
758 - fixes for using large audio device buffers
759 - Windows: add the installation directory to the DLL search path
760 when loading an editor plugin (solves problems with VST and
761 gigedit on systems with other GTK versions installed)
762 - updated linuxsampler man page
763
764 * audio driver:
765 - removed the nonsense audio channel constraint (which was hard coded to
766 max. 100 audio channels) for most audio drivers
767 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
768 opposed to the LSCP specs
769 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
770 reflected the wrong value
771 - fixed a memory management bug in ASIO driver
772 - Makefile fix: JACK_CFLAGS wasn't used
773 - JACK: use jack_client_open instead of the deprecated
774 jack_client_new

777 previous binary release but accidentally never committed to CVS
778 (fixes #117)
779 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
780 win64)
781 - VST: added support for sample rate and buffer size changes
782 - VST: close editor (Fantasia) when the VST is removed
783 - VST: avoid opening Fantasia more than once for each VST instance
784 - VST: export main function as "main" on Linux too (fix for
785 energyXT)
786 - VST: changed number of output channels from one stereo to 16
787 stereo
788 - added channel routing, fxsends and midi maps to the settings
789 stored in the plugin state
790 - performance optimization of AudioChannel::MixTo() and
791 AudioChannel::CopyTo() methods using GCC vector exensions
792 (if available)
793 - ASIO fixes: avoid initializing the device twice, avoid throwing
794 exception when getting parameters from a disconnected device
795
796 * MIDI driver:
797 - added JACK MIDI driver
798 - dispatch bank select as ordinary CC as well, the user might seriously
799 want to (mis)use it for some purpose ("fixed" in all current MIDI
800 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
801 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
802 CoreMidi or AU
803 - fixed mingw-w64 compilation error in MME driver
804 - made program change handling in MIDI thread real-time safe by
805 moving the logic to a non-RT thread
806 - fixed minor memory leak in ALSA driver
807
808 * instruments database:
809 - avoid time consuming samples scanning when adding instruments
810 to the instruments database

815 - work-around for missing fnmatch function on Windows to make
816 instrument database compilable
817 - added instrument database support on Windows
818 works with both standalone mode and VST plugin.
819 the instruments DB file is located in
820 %USERPROFILE%\.linuxsampler\instruments.db which allows different
821 databases for each windows user
822 if no DB is present it automatically creates the .linuxsampler subdir
823 and then creates an empty DB
824 - fixed recursive import, which was broken on Windows
825
826 * Gigasampler format engine:
827 - fixed a memory leak that could happen when a channel was deleted
828 while notes were playing
829 - made it possible to load an instrument even if the audio thread
830 isn't running
831 - added partial support for the "Controller Triggered" MIDI rule,
832 enough for piano gigs with pedal noise samples
833 - minor fix: only mark FX sends as being modified if really the
834 respective FX send MIDI controller was used
835 - added support for GM global device volume SysEx message
836 (can be selected at compile time to either apply globally to the
837 whole sampler [default] or only to the sampler channels that are
838 connected to the respective MIDI input port the SysEx message arrived
839 on)
840 - bugfix: notes triggered at position 0 in the audio buffer were
841 sometimes wrongly killed in the same buffer, causing no sound to
842 be played
843 - added support for chromatic / drumkit mode Roland GS Sysex message
844 which is usally used to switch a part between chromatic sounds and
845 drumkit sounds (as opposed to their common default setting of MIDI
846 part 10 being a drumkit part and all other ones chromatic parts), in
847 LS however one can switch between the first 16 MIDI instrument maps
848 defined for the sampler
849 - made it possible to create multiple sample channels even if the
850 audio thread isn't running
851 - fixed crash when removing channel with active voices (#116)
852 - bugfix: on sample reference changes (instrument editor), only
853 un-cache the respective sample if it's really not used by any
854 sampler engine anymore
855 - re-cache samples in case they were changed by an instrument editor,
856 e.g. when a sample was added while playing (#82)
857 - fixed hanging notes which occured when note-off event had the exact
858 same time stamp as the voice's note-on event and occured both in the
859 same audio fragment cycle (fixes bug #112)
860 - added support for the "fine tune" and "pitch bend range"
861 instrument-level gig parameters
862 - fixed minor artifacts in pitch bend handling
863 - added support for GS Reset SysEx message
864 - allow gig files to use unlimited downward pitch shifting
865 - added a limit check for upward pitch shifting
866 - bugfix: sometimes, when playing a note twice fast, the second
867 note was silent
868 - fixed crash happening when a pitch bend event arrived at the
869 same time a new instrument was loading
870
871 * LSCP server:
872 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
873 react on MIDI data arriving on certain sampler channels (so far only
874 Note-On and Note-Off events are sent via this LSCP event)
875 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
876 react on MIDI data arriving on certain MIDI input devices (so far only
877 Note-On and Note-Off events are sent via this LSCP event)
878 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
879 SET DB_INSTRUMENT FILE_PATH
880 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
881 frontends to send MIDI messages to specific sampler channel
882 - added two additional fields to GET FILE INSTRUMENT INFO command -
883 KEY_BINDINGS and KEYSWITCH_BINDINGS
884 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
885 was incorrect
886 - Optimized the retrieval of the MIDI instrument mappings
887 - added new LSCP command "SET VOICES" to globally alter the maximum
888 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
889 be triggered respectively
890 - added new LSCP command "SET STREAMS" to globally alter the maximum
891 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
892 which will be triggered respectively
893 - bugfix: retry if "select" returns EINTR (this fixes a crash when
894 a gigedit file dialog is opened)
895 - close all connections when LSCPServer is deleted
896 - hard close of all sockets on exit
897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
898 driver
899
900 * Bug fixes:
901 - fixed a crash which occurs when removing a sampler channel waiting
902 to start instrument loading after another channel
903 - fixed a crash which occurs when removing a sampler channel with
904 instrument loading in progress (bug #113)
905 - fixed termination caused by uncaught exception when adding MIDI
906 instrument with PERSISTENT load mode
907 - fixed possible iterator invalidations when resetting the sampler
908 - fixed memory leaks when issuing the following LSCP commands:
909 GET AUDIO_OUTPUT_DRIVER INFO
910 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
911 GET MIDI_INPUT_DRIVER INFO
912 GET MIDI_INPUT_DRIVER_PARAMETER INFO
913 - fixed possible compilation error when sqlite is not present

918 - fixed a low-level atomic load function that was broken on 64-bit
919 PowerPC, which probably could cause crashes on that platform
920 - fixed a memory management error which could cause a crash when a
921 plugin was unloaded
922 - bugfix: two private structs had the same name, which could cause
923 problems if the linker chose the wrong constructor

926
927
928 Version 0.5.1 (6 December 2007)
929
930 * packaging changes:
931 - added autoconf checks for pthread library
932 - added autoconf check for pthread bug found on certain NPTL-enabled
933 glibc versions (see Gentoo bug report #194076)
934 - added autoconf checks for MS Windows
935
936 * general changes:
937 - bugfix: the thread used by an editor plugin didn't die when the
938 editor closed
939 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
940 out all the space. operator--() did not apply size_mask after
941 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
942 order to avoid problems with the _NonVolatileReader functions.
943 - bugfix: Stream.h: added a missing divide by BytesPerSample in
944 GetWriteSpace(). Since this function is currently only used in
945 the stream's qsort() compare function, it didn't trigger any
946 bugs.
947 - Resampler.h, Synthesizer.h: cubic interpolation now works in
948 24bit mode too. Faster method to read 24bit words on little
949 endian machines (x86): replaced 3 byte reads + shifts with a 1
950 unaligned 32bit read and shift
951 - experimental support for MS Windows (MIDI input via MME, AUDIO
952 output via ASIO)
953 - made handling of SIGINT signal (Ctrl-C) a bit more robust
954 - support for monitoring the total number of active disk streams
955 (new LSCP commands: GET TOTAL_STREAM_COUNT,
956 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
957
958 * AUDIO driver:
959 - added Windows ASIO low latency audio driver
960
961 * MIDI driver:
962 - added MME Windows MIDI driver
963
964 * LSCP server:
965 - added support for Windows style path / filenames, however with
966 forward slash path separators instead of backslash
967 (i.e. "C:/foo/bar.gig")
968 - allow naughty liblscp to send non-string device parameters within
969 apostrophes as well
970 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
971 "LIST FILE INSTRUMENTS <file>" and
972 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
973 about an arbitrary instrument file on the system where the sampler is
974 running on
975
976 Version 0.5.0 (15 October 2007)
977
978 * packaging changes:
979 - config.h is not going to be installed along with liblinuxsampler's
980 API header files anymore
981 - only the API relevant header (and source) files will be exported to
982 the Doxygen API documentation (explicitly listed in Doxyfile.in)
983 - added completely new XCode project files for Mac OSX which is now
984 capable to execute our autoconf environment, thus no need anymore
985 to maintain the compile time configuration file (osx/version.h) for
986 OSX manually (patch by Toshi Nagata)
987 - fixed buggy boolean --enable-foo / --disable-foo configure script
988 parameters
989 - global.h now only covers global definitions that are needed for the
990 C++ API header files, all implementation internal global definitions
991 are now in global_private.h
992 - atomic.h is not exposed to the C++ API anymore
993 - no need to include config.h anymore for using LS's API header files
994 - fixed warnings in API doc generation
995
996 * general changes:
997 - replaced the old, confusing MIDI program change mechanism by a
998 flexible MIDI instrument mapper which allows to map arbitrary
999 (MIDI bank, MIDI program) pairs with arbitrary
1000 (engine type, instrument file, file index) triplets which will be
1001 loaded on the respective channel when such MIDI program change
1002 messages arrive, beside that, each entry allows to define a life-time
1003 strategy for the instrument, so the user can define whether the
1004 instrument should i.e. be permanently loaded (to be able to switch
1005 quickly among sounds) or i.e. loaded just on demand when the
1006 respective program change arrives (to safe RAM space), as well as a
1007 global volume factor for each entry, so the user can adjust the volume
1008 dynamic of his mapped instrument collection without having to modify
1009 the instrument files, also one can manage arbitrary amount of such
1010 MIDI instrument maps and assign each sampler channel individually
1011 a certain map, so that i.e. separation of normal instruments and
1012 drumkits is possible
1013 - new notification events for tracking changes to audio/MIDI devices,
1014 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1015 - sampler was limited to load max. 200 instruments in the background
1016 due to a constant size RingBuffer FIFO which is now replaced by a
1017 dynamic (unlimited) size std::list FIFO
1018 - added FX sends, these allow to route audio signals to arbitrary audio
1019 output channels for being processed by external effect processors
1020 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1021 controllers
1022 - global (sampler wide) volume can now be controlled at runtime
1023 - Implemented new, improved notification system
1024 - fixed compilation errors regarding OSX
1025 (patch by Toshi Nagata)
1026 - implemented instruments database
1027 - added support for escape sequences to the instruments database
1028 - added highly experimental support for on-the-fly instrument editing
1029 within the sampler's process (by using instrument editor plugins),
1030 you'll notice the new "Registered instrument editors:" message on
1031 startup, added a new LSCP command:
1032 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1033 to spawn a matching instrument editor for the instrument on the
1034 given sampler channel, the plugin path can be overridden at compile
1035 time with ./configure --enable-plugin-dir=/some/dir
1036 - added experimental code for synchronizing instrument editors hosted
1037 in the sampler's process to safely edit instruments while playing
1038 without a crash (hopefully) by either suspending single regions
1039 wherever possible or if unavoidable whole engine(s)
1040 - fixed several issues in fundamental "Thread" class: set scheduling
1041 policy and priority on thread level, set a minimum stack size for
1042 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1043 threads simply inherited properties of starting thread instead of
1044 setting their own policy and priority
1045 - minor fix in our automatic stack trace mechanism on crashes, the
1046 main process did not wait for the stack trace process to finish
1047 its output
1048 - fixed some minor memory leaks
1049 - reenabled assembly features support, at the moment only for
1050 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1051 - minor assembly fix in x86 features detection (don't use the PIC
1052 register, to avoid relocations in the text segment at runtime)
1053 - POSIX callback functions of Thread.h are hidden
1054
1055 * MIDI driver:
1056 - dispatch bank select (MSB and LSB) messages
1057
1058 * audio driver:
1059 - the ALSA audio output driver parameters now reflect the correct
1060 parameter value ranges for the respective selected sound card
1061 (patch by Till Wimmer, a bit fixed and extended)
1062
1063 * Gigasampler format engine:
1064 - if a filter is used and EG2 finishes before EG1, let the voice
1065 die when EG2 has finished (this fixes a problem with clicks and
1066 voice starvation for some gigs)
1067 - playback is no longer disabled during instrument loading
1068 - all notes playing on a channel that changes its instrument keep
1069 playing with the old instrument until they get a note off
1070 command
1071 - EG fix: a release value of zero could cause noises or crash
1072 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1073 - EG fine tuning: when attack is zero the EG starts at a level
1074 above max sustain level, which means that there is a decay phase
1075 even if sustain is 100%
1076 - more EG fixes: the level could sometimes go below zero and cause
1077 noises or crashes
1078 - minor fix of EGDecay (patch by Toshi Nagata)
1079 - fixed compiler error when --enable-override-filter-type was
1080 supplied to the configure script (fixes #46)
1081 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1082 instead of a fix value
1083 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1084 127 (solo mode) only kill voices if the respective mode really
1085 changed
1086
1087 * LSCP server:
1088 - fixed compile time error for old Bison versions
1089 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1090 - parser now supports extended ASCII character set
1091 (up to ASCII code 255, i.e. includes now umlauts and accents)
1092 - filename arguments in LSCP commands now allow to use escape
1093 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1094 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1095 code value like \xf2) (fixes bug #24)
1096 - the following LSCP commands now also support escape sequences for at
1097 least one of their text-based parameters (i.e. name, description):
1098 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1099 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1100 "SET DB_INSTRUMENT_DIRECTORY NAME",
1101 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1102 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1103 "FIND DB_INSTRUMENT_DIRECTORIES"
1104 - returns verbose syntax errors (line and column where syntax error
1105 occured, the unexpected character and the actually expected, possible
1106 character(s), the latter only if less than 5 possibilities)
1107 - made sure that LSCP syntax is not affected by gigedit locale
1108 settings
1109 - bugfix regarding strings parameter lists: all comma separated lists
1110 of strings were treated as being one string containing commas
1111 (fixes #57)
1112
1113 * Bug fixes:
1114 - fixed crash occurring on certain LSCP scripts (Bug 39)
1115 - another thread safety fix for lscp "load engine" and "set
1116 channel audio output device"
1117 - fixed a crash which occurs when reassigning the same engine
1118 on a sampler channel with connected MIDI device
1119 - fixed a crash which occurs when changing the number of ports of a MIDI
1120 device connected to a sampler channel to number less then or equal
1121 to the index of the port to which the sampler channel is connected.
1122 - The previous bindings were not been disconnected when altering
1123 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1124 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1125 - The active stream/voice count statistic was incorrect.
1126 - notification events were not been sent for some sampler
1127 channel changes
1128 - added default min and max values to restrict the number of allowed
1129 audio output channels and MIDI input ports
1130 - the connection to the PCM interface is now closed when destroying
1131 an audio output device
1132 - files with slash in their path or filename could not be loaded
1133
1134 * test cases:
1135 - updated and fixed (haven't been touched in a while)
1136
1137 Version 0.4.0 (24 November 2006)
1138
1139 * packaging changes:
1140 - changed deprecated copyright attribute to license; added ldconfig
1141 to post-(un)install steps; added devel package for liblinuxsampler;
1142 to linuxsampler.spec (RPM)
1143 - install necessary development header files for allowing 3rd party
1144 applications to link against liblinuxsampler
1145 - liblinuxsampler's API documentation can be generated with 'make docs'
1146 (Doxygen required)
1147 - added benchmark to automatically detect the best triangle LFO
1148 implementation (currently either an integer math solution or a
1149 di-harmonic approximation), automatic detection can be overriden
1150 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1151 configure script argument though (mandatory for cross-compilation)
1152 - do not automatically pick optimized gcc flags if the user already
1153 provided some on his own (as CXXFLAGS)
1154 - added compile time option to disable processing of All-Notes-Off MIDI
1155 messages
1156 - added compile time options to allow disabling the various audio and
1157 MIDI drivers
1158 - fixed automatic GCC CPU switch detection on PPC
1159 (patch by Ebrahim Mayat)
1160
1161 * Gigasampler format engine:
1162 - extensive synthesis optimization
1163 (reimplementation of EGs and LFO(s), removed synthesis parameter
1164 prerendering and the synthesis parameter matrix in general, splitting
1165 each audio fragment into subfragments now where each subfragment uses
1166 constant pitch and filter coefficients. The volume coefficient is
1167 linearly interpolated inside a subfragment, unless
1168 --disable-interpolate-volume is set.)
1169 - fine tuning of the EG modulation parameters
1170 - improved filter cutoff calculation by adding support for the
1171 following gig parameters: Cutoff freq (used when no cutoff
1172 controller is defined), Control invert, Minimum cutoff, Velocity
1173 curve and Velocity range. The keyboard tracking now scales
1174 cutoff frequency instead of resonance.
1175 - added support for gig parameter Resonance.
1176 - fixed bug in sysex handling (patch by Juan Linietsky)
1177 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1178 which can be overridden with --enable-global-attenuation
1179 - EG fixes: made the length of "attack hold" stage more
1180 accurate. Release stage can now start before attack stage
1181 ends. Cancel release didn't work when sustain was zero. Attack
1182 time now has a minimal value to prevent clicks.
1183 - fixed pitch changes larger than one octave
1184 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1185 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1186 all modes can be altered via standard GM messages, that is CC5 for
1187 altering portamento time, CC65 for enabling / disabling portamento
1188 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1189 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1190 parameter) and crossfade
1191 - added support for the "attenuation controller threshold" gig
1192 parameter
1193 - added smoothing of volume changes caused by control change
1194 messages
1195 - sample loop parameters are now taken from the DimensionRegion
1196 instead of the wave chunk
1197 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1198 not equal to a power of two
1199 - reimplementation of the filter algorithm. The new filter is more
1200 accurate and supports all gig filter types, including bandreject
1201 and lowpass turbo.
1202 - real support for 24 bit samples - samples are not truncated to
1203 16 bits anymore
1204 - support for aftertouch (channel pressure, not polyphonic
1205 aftertouch)
1206 - LFO1 behaviour fixed (dampening from max volume instead of
1207 amplifying from 0)
1208
1209 * LSCP server:
1210 - fixed application exit on broken pipe error (fixes bug #20)
1211 - fixed the notification messages delay due to lack of
1212 network activity (fixes bug #26)
1213 - fixed parser bug which occured on space(s) within device parameters
1214 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1215
1216 * audio driver:
1217 - added aRts audio output driver (by no means RT safe)
1218
1219 * MIDI driver:
1220 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1221 messages several times instead of once
1222 - API extension for MIDI drivers which already supply exact time stamps
1223 for events (i.e. for offline rendering based MIDI drivers)
1224 - added checks for bad MIDI data
1225
1226 * linuxsampler application:
1227 - show available sampler engine types on startup
1228
1229 * general changes:
1230 - support for muting sampler channels and solo mode of the same, two new
1231 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1232 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1233 introduced for this, the behavior is the same like on a mixer console
1234 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1235 --enable-process-muted-channels which can be used to enable the
1236 processing of muted channels.
1237 - support for sostenuto pedal
1238 - support for monitoring the total number of active voices
1239 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1240 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1241 - fixed some memory management errors
1242 - fixed some concurrency problems that could lead to crashes when
1243 LSCP commands were executed
1244 - fixed crash when instrument loading failed previously on the same
1245 sampler channel (fixes bug #36)
1246
1247 Version 0.3.3 (15 July 2005)
1248
1249 * packaging changes:
1250 - fixed compilation with gcc 4.0
1251
1252 * Gigasampler format engine:
1253 - LFO preprocessing was performed even though the respective LFO was
1254 disabled by the instrument patch (minor efficiency fix)
1255 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1256 for volume ramp downs in the same fragment (needed for current voice
1257 stealing implementation) then simply inform the user with a warning
1258 about possible click sounds and reduce the volume ramp down
1259 appropriately instead of cancelling the audio device connection
1260
1261 Version 0.3.2 (24 June 2005)
1262
1263 * packaging changes:
1264 - updated autotools build files to compile on OS X
1265 (conditional compilation of CoreMIDI and MidiShare drivers)
1266 - hand-crafted assembly optimization code can be disabled with
1267 './configure --disable-asm' (definitely not recommended)
1268 - fixed 'make dist' rule to include all necessary files
1269 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1270 (due to 'dist-bzip2' automake option)
1271
1272 * Gigasampler format engine:
1273 - support for the gig parameters for "release velocity response" curves
1274 - fine tuning of the EGADSR envelope
1275 - volume of release triggered samples now depends on note-on velocity,
1276 note length and gig parameter "release trigger decay" instead of
1277 note-off velocity.
1278 - revised voice stealing
1279 (fixes crash and endless loop caused by voice stealing)
1280 - don't reset scale tuning on instrument or audio output device change
1281 - handle key group conflicts right at the beginning of each fragment
1282 instead of when the respective voice is actually launched
1283 (fixes undefined behavior if stolen voices belonged to a key group -
1284 this case was followed by a "killed voice survived" error message)
1285 - fixed minor issue with null/silence samples
1286 (those stole voices even though they don't need a voice at all which
1287 resulted in "voice stealing didn't work out" messages)
1288 - don't reset volume, pan, pitch and MIDI controller values on
1289 instrument or audio output device change
1290
1291 * LSCP server:
1292 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1293 - fixed LSCP event "CHANNEL_INFO" notification
1294 (e.g. did not notify on volume changes or MIDI program change events)
1295
1296 * linuxsampler application:
1297 - added command line parameters --lscp-addr and --lscp-port to override
1298 default IP address and port of LSCP server
1299
1300 Version 0.3.1 (24 May 2005)
1301
1302 * initial release
