1    Version CVS HEAD (?)
2    
3      * plugin changes:
4        - LV2 Persist + Files support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
8        - Mac OS X: support the new dir for Core Audio SDK
9        - Mac OS X: fixed building outside source directory
10        - made sure all source files for hostplugins are included when
11          doing "make dist"
12        - removed empty directories left from the cvs to svn migration
13        - fixed compilation with gcc 4.6.1
14        - another "make dist" fix, for the LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16        - minor Makefile fix for building lscpparser when build and source
17          directories are separate
18        - Mac OS X: made it possible to specify plugin installation dir to
19          configure
20        - Mac OS X: Makefile fix for the install-strip target
21    
22      * general changes:
23        - Refactoring: moved the independent code from
24          the Gigasampler format engine to base classes
25        - command line option '--profile' is currently disabled, since the
26          respective profiling code is currently broken
27        - Introduced support for optional environment variable
28          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29          where the sampler shall look for instrument editor plugins
30          (patch by Luis Garrido, slightly modified).
31        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34          note (in this implementation of the sampler its simply hard routed to
35          the 1st effect send of the sampler channel, no matter what the actual
36          effect type is)
37        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 2nd effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented support for internal LADSPA effects
42        - raised limit of program change queue from 100 to 512
43          (as suggested by Alex Stone)
44    
45      * Gigasampler format engine:
46        - implemented the "round robin keyboard" dimension
47        - fixed round robin and random dimensions for cases when number of
48          dimension zones is not a power of two
49        - made round robin use a counter for each region instead of each
50          key
51    
52      * SFZ format engine:
53        - Initial implementation (not usable yet)
54        - added support for v2 multiple stage envelope generators
55        - added a fine-tuned v1 envelope generator instead of using the
56          one from the gig engine
57        - fixed memory leak and memory handling errors
58        - added support for trigger=first, trigger=legato and sw_previous
59        - allow non-numerical key values ("C#4" for example)

61        - fixed error when unloading instrument with same sample used by
62          multiple regions
63        - added some opcode aliases, like loopmode for loop_mode, to be
64          more compatible

66        - added support for off_mode=normal
67        - added support for random, seq_position, seq_length and volume
68        - added v1 LFO opcodes to parser (no support in engine yet)

74        - added more v1 aliases to parser
75        - reduced memory usage for sfz data
76        - RT-safeness: avoid malloc in audio thread
77        - fixed a bug that could cause voice stealing to fail
78        - optimized sample lookup
79        - improved support for exclusive groups (group, off_by and
80          off_mode)
81        - added support for controller triggered regions (on_locc/on_hicc)
82        - added support for loop_mode=one_shot
83        - fixed playback of 16 bit wav files on big endian CPUs
84        - added support for Ogg Vorbis sample files
85        - use loop markers from sample file if loop_start and loop_end are
86          not set in sfz file
87        - implemeted filters. Filter types: lowpass, bandpass, bandreject
88          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
89          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,

92        - added support for velocity effect on amplifier envelope time
93          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
94          ampeg_vel2release)
95        - added support for EG hold (ampeg_hold)
96        - added support for sample offset (offset)

104        - initial implementation of cutoff filter
105    
106      * Gigasampler format engine:
107        - bugfix: pitch LFO controller "internal+aftertouch" was broken
108        - bugfix: filter keyboard tracking was broken
109        - filter performance fix (an unnecessary copy was made of the
110          filter parameters in each sub fragment)
111    
112      * Host plugins:
113        - AU bugfix: failed to destroy its audio/MIDI devices
114        - Listen to all interfaces on Mac OS X (INADDR_ANY)
115        - VST bugfix: If the host called resume() before and after
116          changing sample rate or block size, the number of channels was
117          incorrectly set to two. This caused silence in Cubase 5.
118        - save engine type (gig, sfz or sf2) in plugin state
119        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
120          64 bit Windows
121        - AU: changed number of output channels from one stereo to 16
122          stereo
123        - VST: made it possible to build the VST plugin for Mac
124        - AU: link AU plugin dynamically if --disable-shared isn't
125          specified
126

128        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
129          the ALSA sequencer client name
130        - removed limit of maximum amount of MIDI ports per MIDI device, since
131          there is no reason for this limit
132    
133      * audio driver:
134        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
135    
136      * LSCP server:
137        - added support for sending MIDI CC messages via LSCP command
138          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

160        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>
161          <effect-chain> <effect-instance>"
162        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
163          <effect-chain> <effect-chain-pos> <effect-instance>"

172    
173      * Bug fixes:
174        - Fixed crash which may occur when MIDI key + transpose is out of range
175        - minor valgrind fixes
176        - fixed crash which occurred when changing an already deployed sampler
177          channel to a different engine type
178        - fixed crash when deleting a sampler channel or changing engine
179          type while an instrument load was in progress
180        - bugfix: playing a note while changing the instrument could cause
181          a crash, or give "Handing back unknown region" error messages
182        - bugfix: calling SET VOICES (which Fantasia does on start and
183          refresh) could cause instruments to be unloaded
184        - Mac OS X: fixed name collision of enum in EffectControl and
185          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
186        - Mac OS X: fixed hanging threads
187        - Windows: disabled the previous thread fix on non-Mac systems, as
188          it caused hanging threads on Windows
189        - Fixed possible crashes due to corrupted MIDI/audio device list
190          after MIDI/audio device creation failure
191    
192    Version 1.0.0 (31 July 2009)
193    
194      * packaging changes:
195        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
196          causing e.g. the libgig test to fail when
197          "./configure --disable-jack-driver" was used
198          (patch by Alexis Ballier)
199        - fixed compilation with gcc 4.3
200        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
201        - fixed configure so it detects x86_64 (#107)
202        - fixes for building with newer MinGW versions
203        - fix for building with bison 2.4 (#111)
204        - fixed building with libgig installed in a non-standard directory
205        - minor fix in configure for mmsystem.h detection on MinGW
206        - Windows: look for editor plugins and Fantasia using base
207          directory of liblinuxsampler dll (look in the same directory and one
208          directory above)
209        - configure script fix: removed unconditional use of SSE
210        - fixed building with sqlite installed in a non-standard directory
211        - when cross-compiling, don't try to create instruments.db
212        - fix for new mingw-w64 version, which has usleep
213    
214      * general changes:
215        - bugfix: on some POSIX systems instrument editor plugins refused to
216          load as we used a non-portable Linux specific struct field
217          (fixes bug #70, patch by Ronald Baljeu)
218        - fixed endless loop which occured when loading an instrument editor
219          plugin DLL on Windows systems failed
220        - fixed memory leaks that occurred when liblinuxsampler was unloaded
221        - optimized the SynchronizedConfig class so it doesn't wait
222          unnecessarily long after an update
223        - added support for notifying instrument editors on note-on / note-off
224          events (e.g. to highlight the pressed keys on the virtual keyboard
225          of gigedit)
226        - added support for triggering notes by instrument editors (see above)
227        - be verbose on DLL load errors (on Linux)
228        - fixed di-harmonic triangle LFO implementation (this LFO implementation
229          is only used by very few systems, most pick the int math
230          implementation, which is usually faster)
231        - fixes for audio drivers with varying buffer sizes
232        - experimental support for running LinuxSampler as a DSSI, LV2 and
233          VST plugin
234        - notification events for stream/voice count statistics are now sent
235          only when there are actual changes
236        - added memory ordering constraints to improve stability on
237          multi-core and multi-cpu systems
238        - maximum voices and disk streams can now be altered at runtime
239        - fixed CPU feature detection on x86_64 (maybe fixes #108)
240        - automatic stacktrace mechanism is now turned off by default and can
241          be switched on by command line option "--stacktrace" (the automatic
242          stacktrace mechanism seems to be broken on most systems at the moment)
243        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
244          a pointer to the launched InstrumentEditor object
245        - added optional 3rd party user data parameter for following
246          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
247          InstrumentEditor::Launch(),
248          InstrumentManager::LaunchInstrumentEditor()
249        - theoretical fix: made SynchronizedConfig follow C++0x memory
250          model more strictly
251        - fixes for using large audio device buffers
252        - Windows: add the installation directory to the DLL search path
253          when loading an editor plugin (solves problems with VST and
254          gigedit on systems with other GTK versions installed)
255    
256      * audio driver:
257        - removed the nonsense audio channel constraint (which was hard coded to
258          max. 100 audio channels) for most audio drivers
259        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
260          opposed to the LSCP specs
261        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
262          reflected the wrong value
263        - fixed a memory management bug in ASIO driver
264        - Makefile fix: JACK_CFLAGS wasn't used
265        - JACK: use jack_client_open instead of the deprecated
266          jack_client_new
267        - added (experimental) CoreAudio driver
268        - applied old fixes to the ASIO driver that were included in the
269          previous binary release but accidentally never committed to CVS
270          (fixes #117)
271        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
272          win64)
273        - VST: added support for sample rate and buffer size changes
274        - VST: close editor (Fantasia) when the VST is removed
275        - VST: avoid opening Fantasia more than once for each VST instance
276        - VST: export main function as "main" on Linux too (fix for
277          energyXT)
278        - VST: changed number of output channels from one stereo to 16
279          stereo
280        - added channel routing, fxsends and midi maps to the settings
281          stored in the plugin state
282        - performance optimization of AudioChannel::MixTo() and
283          AudioChannel::CopyTo() methods using GCC vector exensions
284          (if available)
285        - ASIO fixes: avoid initializing the device twice, avoid throwing
286          exception when getting parameters from a disconnected device
287    
288      * MIDI driver:
289        - added JACK MIDI driver
290        - dispatch bank select as ordinary CC as well, the user might seriously
291          want to (mis)use it for some purpose ("fixed" in all current MIDI
292          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
293        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
294          CoreMidi or AU
295        - fixed mingw-w64 compilation error in MME driver
296        - made program change handling in MIDI thread real-time safe by
297          moving the logic to a non-RT thread
298        - fixed minor memory leak in ALSA driver
299    
300      * instruments database:
301        - avoid time consuming samples scanning when adding instruments
302          to the instruments database
303        - added support for handling lost files in the instruments database
304        - Implemented option for adding instruments in separate directories
305          in the instruments database
306          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
307        - work-around for missing fnmatch function on Windows to make
308          instrument database compilable
309        - added instrument database support on Windows
310          works with both standalone mode and VST plugin.
311          the instruments DB file is located in
312          %USERPROFILE%\.linuxsampler\instruments.db which allows different
313          databases for each windows user
314          if no DB is present it automatically creates the .linuxsampler subdir
315          and then creates an empty DB
316        - fixed recursive import, which was broken on Windows
317    
318      * Gigasampler format engine:
319        - fixed a memory leak that could happen when a channel was deleted
320          while notes were playing
321        - made it possible to load an instrument even if the audio thread
322          isn't running
323        - added partial support for the "Controller Triggered" MIDI rule,
324          enough for piano gigs with pedal noise samples
325        - minor fix: only mark FX sends as being modified if really the
326          respective FX send MIDI controller was used
327        - added support for GM global device volume SysEx message
328          (can be selected at compile time to either apply globally to the
329          whole sampler [default] or only to the sampler channels that are
330          connected to the respective MIDI input port the SysEx message arrived
331          on)
332        - bugfix: notes triggered at position 0 in the audio buffer were
333          sometimes wrongly killed in the same buffer, causing no sound to
334          be played
335        - added support for chromatic / drumkit mode Roland GS Sysex message
336          which is usally used to switch a part between chromatic sounds and
337          drumkit sounds (as opposed to their common default setting of MIDI
338          part 10 being a drumkit part and all other ones chromatic parts), in
339          LS however one can switch between the first 16 MIDI instrument maps
340          defined for the sampler
341        - made it possible to create multiple sample channels even if the
342          audio thread isn't running
343        - fixed crash when removing channel with active voices (#116)
344        - bugfix: on sample reference changes (instrument editor), only
345          un-cache the respective sample if it's really not used by any
346          sampler engine anymore
347        - re-cache samples in case they were changed by an instrument editor,
348          e.g. when a sample was added while playing (#82)
349        - fixed hanging notes which occured when note-off event had the exact
350          same time stamp as the voice's note-on event and occured both in the
351          same audio fragment cycle (fixes bug #112)
352        - added support for the "fine tune" and "pitch bend range"
353          instrument-level gig parameters
354        - fixed minor artifacts in pitch bend handling
355        - added support for GS Reset SysEx message
356        - allow gig files to use unlimited downward pitch shifting
357        - added a limit check for upward pitch shifting
358        - bugfix: sometimes, when playing a note twice fast, the second
359          note was silent
360        - fixed crash happening when a pitch bend event arrived at the
361          same time a new instrument was loading
362    
363      * LSCP server:
364        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
365          react on MIDI data arriving on certain sampler channels (so far only
366          Note-On and Note-Off events are sent via this LSCP event)
367        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
368          react on MIDI data arriving on certain MIDI input devices (so far only
369          Note-On and Note-Off events are sent via this LSCP event)
370        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
371          SET DB_INSTRUMENT FILE_PATH
372        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
373          frontends to send MIDI messages to specific sampler channel
374        - added two additional fields to GET FILE INSTRUMENT INFO command -
375          KEY_BINDINGS and KEYSWITCH_BINDINGS
376        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
377          was incorrect
378        - Optimized the retrieval of the MIDI instrument mappings
379        - added new LSCP command "SET VOICES" to globally alter the maximum
380          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
381          be triggered respectively
382        - added new LSCP command "SET STREAMS" to globally alter the maximum
383          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
384          which will be triggered respectively
385        - bugfix: retry if "select" returns EINTR (this fixes a crash when
386          a gigedit file dialog is opened)
387        - close all connections when LSCPServer is deleted
388        - hard close of all sockets on exit
389        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
390          driver
391    
392      * Bug fixes:
393        - fixed a crash which occurs when removing a sampler channel waiting
