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)
60        - "key" opcode now sets pitch_keycenter too
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

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,

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)
97        - use the newly introduced signal units model

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

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

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

173    
174      * Bug fixes:
175        - Fixed crash which may occur when MIDI key + transpose is out of range
176        - minor valgrind fixes
177        - fixed crash which occurred when changing an already deployed sampler
178          channel to a different engine type
179        - fixed crash when deleting a sampler channel or changing engine
180          type while an instrument load was in progress
181        - bugfix: playing a note while changing the instrument could cause
182          a crash, or give "Handing back unknown region" error messages
183        - bugfix: calling SET VOICES (which Fantasia does on start and
184          refresh) could cause instruments to be unloaded
185        - Mac OS X: fixed name collision of enum in EffectControl and
186          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
187        - Mac OS X: fixed hanging threads
188        - Windows: disabled the previous thread fix on non-Mac systems, as
189          it caused hanging threads on Windows
190        - Fixed possible crashes due to corrupted MIDI/audio device list
191          after MIDI/audio device creation failure
192    
193    Version 1.0.0 (31 July 2009)
194    
195      * packaging changes:
196        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
197          causing e.g. the libgig test to fail when
198          "./configure --disable-jack-driver" was used
199          (patch by Alexis Ballier)
200        - fixed compilation with gcc 4.3
201        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
202        - fixed configure so it detects x86_64 (#107)
203        - fixes for building with newer MinGW versions
204        - fix for building with bison 2.4 (#111)
205        - fixed building with libgig installed in a non-standard directory
206        - minor fix in configure for mmsystem.h detection on MinGW
207        - Windows: look for editor plugins and Fantasia using base
208          directory of liblinuxsampler dll (look in the same directory and one
209          directory above)
210        - configure script fix: removed unconditional use of SSE
211        - fixed building with sqlite installed in a non-standard directory
212        - when cross-compiling, don't try to create instruments.db
213        - fix for new mingw-w64 version, which has usleep
214    
215      * general changes:
216        - bugfix: on some POSIX systems instrument editor plugins refused to
217          load as we used a non-portable Linux specific struct field
218          (fixes bug #70, patch by Ronald Baljeu)
219        - fixed endless loop which occured when loading an instrument editor
220          plugin DLL on Windows systems failed
221        - fixed memory leaks that occurred when liblinuxsampler was unloaded
222        - optimized the SynchronizedConfig class so it doesn't wait
223          unnecessarily long after an update
224        - added support for notifying instrument editors on note-on / note-off
225          events (e.g. to highlight the pressed keys on the virtual keyboard
226          of gigedit)
227        - added support for triggering notes by instrument editors (see above)
228        - be verbose on DLL load errors (on Linux)
229        - fixed di-harmonic triangle LFO implementation (this LFO implementation
230          is only used by very few systems, most pick the int math
231          implementation, which is usually faster)
232        - fixes for audio drivers with varying buffer sizes
233        - experimental support for running LinuxSampler as a DSSI, LV2 and
234          VST plugin
235        - notification events for stream/voice count statistics are now sent
236          only when there are actual changes
237        - added memory ordering constraints to improve stability on
238          multi-core and multi-cpu systems
239        - maximum voices and disk streams can now be altered at runtime
240        - fixed CPU feature detection on x86_64 (maybe fixes #108)
241        - automatic stacktrace mechanism is now turned off by default and can
242          be switched on by command line option "--stacktrace" (the automatic
243          stacktrace mechanism seems to be broken on most systems at the moment)
244        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
245          a pointer to the launched InstrumentEditor object
246        - added optional 3rd party user data parameter for following
247          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
248          InstrumentEditor::Launch(),
249          InstrumentManager::LaunchInstrumentEditor()
250        - theoretical fix: made SynchronizedConfig follow C++0x memory
251          model more strictly
252        - fixes for using large audio device buffers
253        - Windows: add the installation directory to the DLL search path
254          when loading an editor plugin (solves problems with VST and
255          gigedit on systems with other GTK versions installed)
256    
257      * audio driver:
258        - removed the nonsense audio channel constraint (which was hard coded to
259          max. 100 audio channels) for most audio drivers
260        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
261          opposed to the LSCP specs
262        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
263          reflected the wrong value
264        - fixed a memory management bug in ASIO driver
265        - Makefile fix: JACK_CFLAGS wasn't used
266        - JACK: use jack_client_open instead of the deprecated
267          jack_client_new
268        - added (experimental) CoreAudio driver
269        - applied old fixes to the ASIO driver that were included in the
270          previous binary release but accidentally never committed to CVS
271          (fixes #117)
272        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
273          win64)
274        - VST: added support for sample rate and buffer size changes
275        - VST: close editor (Fantasia) when the VST is removed
276        - VST: avoid opening Fantasia more than once for each VST instance
277        - VST: export main function as "main" on Linux too (fix for
278          energyXT)
279        - VST: changed number of output channels from one stereo to 16
280          stereo
281        - added channel routing, fxsends and midi maps to the settings
282          stored in the plugin state
283        - performance optimization of AudioChannel::MixTo() and
284          AudioChannel::CopyTo() methods using GCC vector exensions
285          (if available)
286        - ASIO fixes: avoid initializing the device twice, avoid throwing
287          exception when getting parameters from a disconnected device
288    
289      * MIDI driver:
290        - added JACK MIDI driver
291        - dispatch bank select as ordinary CC as well, the user might seriously
292          want to (mis)use it for some purpose ("fixed" in all current MIDI
293          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
294        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
295          CoreMidi or AU
296        - fixed mingw-w64 compilation error in MME driver
297        - made program change handling in MIDI thread real-time safe by
298          moving the logic to a non-RT thread
299        - fixed minor memory leak in ALSA driver
300    
301      * instruments database:
302        - avoid time consuming samples scanning when adding instruments
303          to the instruments database
304        - added support for handling lost files in the instruments database
305        - Implemented option for adding instruments in separate directories
306          in the instruments database
307          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
308        - work-around for missing fnmatch function on Windows to make
309          instrument database compilable
310        - added instrument database support on Windows
311          works with both standalone mode and VST plugin.
312          the instruments DB file is located in
313          %USERPROFILE%\.linuxsampler\instruments.db which allows different
314          databases for each windows user
315          if no DB is present it automatically creates the .linuxsampler subdir
316          and then creates an empty DB
317        - fixed recursive import, which was broken on Windows
318    
319      * Gigasampler format engine:
320        - fixed a memory leak that could happen when a channel was deleted
321          while notes were playing
322        - made it possible to load an instrument even if the audio thread
323          isn't running
324        - added partial support for the "Controller Triggered" MIDI rule,
325          enough for piano gigs with pedal noise samples
326        - minor fix: only mark FX sends as being modified if really the
327          respective FX send MIDI controller was used
328        - added support for GM global device volume SysEx message
329          (can be selected at compile time to either apply globally to the
330          whole sampler [default] or only to the sampler channels that are
331          connected to the respective MIDI input port the SysEx message arrived
332          on)
333        - bugfix: notes triggered at position 0 in the audio buffer were
334          sometimes wrongly killed in the same buffer, causing no sound to
335          be played
336        - added support for chromatic / drumkit mode Roland GS Sysex message
337          which is usally used to switch a part between chromatic sounds and
338          drumkit sounds (as opposed to their common default setting of MIDI
339          part 10 being a drumkit part and all other ones chromatic parts), in
340          LS however one can switch between the first 16 MIDI instrument maps
341          defined for the sampler
342        - made it possible to create multiple sample channels even if the
343          audio thread isn't running
344        - fixed crash when removing channel with active voices (#116)
345        - bugfix: on sample reference changes (instrument editor), only
346          un-cache the respective sample if it's really not used by any
347          sampler engine anymore
348        - re-cache samples in case they were changed by an instrument editor,
349          e.g. when a sample was added while playing (#82)
350        - fixed hanging notes which occured when note-off event had the exact
351          same time stamp as the voice's note-on event and occured both in the
352          same audio fragment cycle (fixes bug #112)
353        - added support for the "fine tune" and "pitch bend range"
354          instrument-level gig parameters
355        - fixed minor artifacts in pitch bend handling
356        - added support for GS Reset SysEx message
357        - allow gig files to use unlimited downward pitch shifting
358        - added a limit check for upward pitch shifting
359        - bugfix: sometimes, when playing a note twice fast, the second
360          note was silent
361        - fixed crash happening when a pitch bend event arrived at the
362          same time a new instrument was loading
363    
364      * LSCP server:
365        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
366          react on MIDI data arriving on certain sampler channels (so far only
367          Note-On and Note-Off events are sent via this LSCP event)
368        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
369          react on MIDI data arriving on certain MIDI input devices (so far only
370          Note-On and Note-Off events are sent via this LSCP event)
371        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
372          SET DB_INSTRUMENT FILE_PATH
373        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
374          frontends to send MIDI messages to specific sampler channel
375        - added two additional fields to GET FILE INSTRUMENT INFO command -
376          KEY_BINDINGS and KEYSWITCH_BINDINGS
377        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
378          was incorrect
379        - Optimized the retrieval of the MIDI instrument mappings
380        - added new LSCP command "SET VOICES" to globally alter the maximum
381          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
382          be triggered respectively
383        - added new LSCP command "SET STREAMS" to globally alter the maximum
384          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
385          which will be triggered respectively
386        - bugfix: retry if "select" returns EINTR (this fixes a crash when
387          a gigedit file dialog is opened)
388        - close all connections when LSCPServer is deleted
389        - hard close of all sockets on exit
390        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
391          driver
392    
393      * Bug fixes:
394        - fixed a crash which occurs when removing a sampler channel waiting
395          to start instrument loading after another channel
396        - fixed a crash which occurs when removing a sampler channel with
397          instrument loading in progress (bug #113)
398        - fixed termination caused by uncaught exception when adding MIDI
399          instrument with PERSISTENT load mode
400        - fixed possible iterator invalidations when resetting the sampler
401        - fixed memory leaks when issuing the following LSCP commands:
402          GET AUDIO_OUTPUT_DRIVER INFO
403          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
404          GET MIDI_INPUT_DRIVER INFO
405          GET MIDI_INPUT_DRIVER_PARAMETER INFO
406        - fixed possible compilation error when sqlite is not present
407        - fixed orphaned pointers when setting maximum voices limit (bug #118)
408        - fixed crash when changing the audio output device of a sampler
409          channel with loaded instrument and start playing notes
410        - fixed endless loop in Engine::SuspendAll() (bug #120)
411        - fixed a low-level atomic load function that was broken on 64-bit
412          PowerPC, which probably could cause crashes on that platform
413        - fixed a memory management error which could cause a crash when a
414          plugin was unloaded
415        - bugfix: two private structs had the same name, which could cause
416          problems if the linker chose the wrong constructor
417        - fixed low-level ConditionServer usage bug that caused lockups on
418          Windows

431        editor closed        editor closed
432        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
433          out all the space. operator--() did not apply size_mask after
434          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
435          order to avoid problems with the _NonVolatileReader functions.
436        - bugfix: Stream.h: added a missing divide by BytesPerSample in
437          GetWriteSpace(). Since this function is currently only used in
438          the stream's qsort() compare function, it didn't trigger any
439          bugs.
440        - Resampler.h, Synthesizer.h: cubic interpolation now works in
441          24bit mode too. Faster method to read 24bit words on little
442          endian machines (x86): replaced 3 byte reads + shifts with a 1
443          unaligned 32bit read and shift
444        - experimental support for MS Windows (MIDI input via MME, AUDIO
445          output via ASIO)
446        - made handling of SIGINT signal (Ctrl-C) a bit more robust
447        - support for monitoring the total number of active disk streams
448          (new LSCP commands: GET TOTAL_STREAM_COUNT,
449          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
450    
451      * AUDIO driver:
452        - added Windows ASIO low latency audio driver
453    
454      * MIDI driver:
455        - added MME Windows MIDI driver
456    
457      * LSCP server:
458        - added support for Windows style path / filenames, however with
459          forward slash path separators instead of backslash
460          (i.e. "C:/foo/bar.gig")
461        - allow naughty liblscp to send non-string device parameters within
462          apostrophes as well
463        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
464          "LIST FILE INSTRUMENTS <file>" and
465          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
466          about an arbitrary instrument file on the system where the sampler is
467          running on
