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 LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16    
17      * general changes:
18        - Refactoring: moved the independent code from
19          the Gigasampler format engine to base classes
20        - command line option '--profile' is currently disabled, since the
21          respective profiling code is currently broken
22        - Introduced support for optional environment variable
23          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
24          where the sampler shall look for instrument editor plugins
25          (patch by Luis Garrido, slightly modified).
26        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
27        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
28        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
29          note (in this implementation of the sampler its simply hard routed to
30          the 1st effect send of the sampler channel, no matter what the actual
31          effect type is)
32        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
33          note (in this implementation of the sampler its simply hard routed to
34          the 2nd effect send of the sampler channel, no matter what the actual
35          effect type is)
36        - implemented support for internal LADSPA effects
37        - raised limit of program change queue from 100 to 512
38          (as suggested by Alex Stone)
39    
40      * Gigasampler format engine:
41        - implemented the "round robin keyboard" dimension
42        - fixed round robin and random dimensions for cases when number of
43          dimension zones is not a power of two
44        - made round robin use a counter for each region instead of each
45          key
46    
47      * SFZ format engine:
48        - Initial implementation (not usable yet)
49        - added support for v2 multiple stage envelope generators
50        - added a fine-tuned v1 envelope generator instead of using the
51          one from the gig engine
52        - fixed memory leak and memory handling errors
53        - added support for trigger=first, trigger=legato and sw_previous
54        - allow non-numerical key values ("C#4" for example)
55        - "key" opcode now sets pitch_keycenter too
56        - fixed error when unloading instrument with same sample used by
57          multiple regions
58        - added some opcode aliases, like loopmode for loop_mode, to be
59          more compatible
60        - added support for trigger=release and rt_decay
61        - added support for off_mode=normal
62        - added support for random, seq_position, seq_length and volume
63        - added v1 LFO opcodes to parser (no support in engine yet)
64        - added support for amp_veltrack and amp_velcurve_N
65        - fine-tuned the default velocity curve
66        - added support for transpose

68        - improved logic for sw_lokey/hikey/up/down/last
69        - added more v1 aliases to parser
70        - reduced memory usage for sfz data
71        - RT-safeness: avoid malloc in audio thread
72        - fixed a bug that could cause voice stealing to fail
73        - optimized sample lookup
74        - improved support for exclusive groups (group, off_by and
75          off_mode)
76        - added support for controller triggered regions (on_locc/on_hicc)
77        - added support for loop_mode=one_shot
78        - fixed playback of 16 bit wav files on big endian CPUs
79        - added support for Ogg Vorbis sample files
80        - use loop markers from sample file if loop_start and loop_end are
81          not set in sfz file
82        - implemeted filters. Filter types: lowpass, bandpass, bandreject
83          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
84          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
85          cutoff_cc, cutoff_chanaft.
86        - bugfix: zero ampeg_sustain didn't work
87        - added support for velocity effect on amplifier envelope time
88          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
89          ampeg_vel2release)
90    
91      * SoundFont format engine:
92        - Initial implementation (not usable yet)
93        - RT-safeness: avoid malloc in audio thread
94        - fixed a bug that could cause voice stealing to fail
95    
96      * Gigasampler format engine:
97        - bugfix: pitch LFO controller "internal+aftertouch" was broken
98        - bugfix: filter keyboard tracking was broken
99        - filter performance fix (an unnecessary copy was made of the
100          filter parameters in each sub fragment)
101    
102      * Host plugins:
103        - AU bugfix: failed to destroy its audio/MIDI devices
104        - Listen to all interfaces on Mac OS X (INADDR_ANY)
105        - VST bugfix: If the host called resume() before and after
106          changing sample rate or block size, the number of channels was
107          incorrectly set to two. This caused silence in Cubase 5.
108        - save engine type (gig, sfz or sf2) in plugin state
109        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
110          64 bit Windows
111    
112      * MIDI driver:
113        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
114          the ALSA sequencer client name
115        - removed limit of maximum amount of MIDI ports per MIDI device, since
116          there is no reason for this limit
117    
118      * audio driver:
119        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
120

147        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
148          <effect-chain> <effect-chain-pos> <effect-instance>"
149        - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>
150          <effect-chain> <chain-pos>"

152          <fx_send_id> <effect_chain> <chain_pos>"
153        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
154    
155      * Bug fixes:
156        - Fixed crash which may occur when MIDI key + transpose is out of range
157        - minor valgrind fixes
158        - fixed crash which occured when changing an already deployed sampler
159          channel to a different engine type
160        - fixed crash when deleting a sampler channel or changing engine
161          type while an instrument load was in progress
162        - bugfix: playing a note while changing the instrument could cause
163          a crash, or give "Handing back unknown region" error messages
164        - bugfix: calling SET VOICES (which Fantasia does on start and
165          refresh) could cause instruments to be unloaded
166        - Mac OS X: fixed name collision of enum in EffectControl and
167          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
168        - Mac OS X: fixed hanging threads
169    
170    Version 1.0.0 (31 July 2009)
171    
172      * packaging changes:
173        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
174          causing e.g. the libgig test to fail when
175          "./configure --disable-jack-driver" was used
176          (patch by Alexis Ballier)
177        - fixed compilation with gcc 4.3
178        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
179        - fixed configure so it detects x86_64 (#107)
180        - fixes for building with newer MinGW versions
181        - fix for building with bison 2.4 (#111)
182        - fixed building with libgig installed in a non-standard directory
183        - minor fix in configure for mmsystem.h detection on MinGW
184        - Windows: look for editor plugins and Fantasia using base
185          directory of liblinuxsampler dll (look in the same directory and one
186          directory above)
187        - configure script fix: removed unconditional use of SSE
188        - fixed building with sqlite installed in a non-standard directory
189        - when cross-compiling, don't try to create instruments.db
190        - fix for new mingw-w64 version, which has usleep
191    
192      * general changes:
193        - bugfix: on some POSIX systems instrument editor plugins refused to
194          load as we used a non-portable Linux specific struct field
195          (fixes bug #70, patch by Ronald Baljeu)
196        - fixed endless loop which occured when loading an instrument editor
197          plugin DLL on Windows systems failed
198        - fixed memory leaks that occurred when liblinuxsampler was unloaded
199        - optimized the SynchronizedConfig class so it doesn't wait
200          unnecessarily long after an update
201        - added support for notifying instrument editors on note-on / note-off
202          events (e.g. to highlight the pressed keys on the virtual keyboard
203          of gigedit)
204        - added support for triggering notes by instrument editors (see above)
205        - be verbose on DLL load errors (on Linux)
206        - fixed di-harmonic triangle LFO implementation (this LFO implementation
207          is only used by very few systems, most pick the int math
208          implementation, which is usually faster)
209        - fixes for audio drivers with varying buffer sizes
210        - experimental support for running LinuxSampler as a DSSI, LV2 and
211          VST plugin
212        - notification events for stream/voice count statistics are now sent
213          only when there are actual changes
214        - added memory ordering constraints to improve stability on
215          multi-core and multi-cpu systems
216        - maximum voices and disk streams can now be altered at runtime
217        - fixed CPU feature detection on x86_64 (maybe fixes #108)
218        - automatic stacktrace mechanism is now turned off by default and can
219          be switched on by command line option "--stacktrace" (the automatic
220          stacktrace mechanism seems to be broken on most systems at the moment)
221        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
222          a pointer to the launched InstrumentEditor object
223        - added optional 3rd party user data parameter for following
224          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
225          InstrumentEditor::Launch(),
226          InstrumentManager::LaunchInstrumentEditor()
227        - theoretical fix: made SynchronizedConfig follow C++0x memory
228          model more strictly
229        - fixes for using large audio device buffers
230        - Windows: add the installation directory to the DLL search path
231          when loading an editor plugin (solves problems with VST and
232          gigedit on systems with other GTK versions installed)
233    
234      * audio driver:
235        - removed the nonsense audio channel constraint (which was hard coded to
236          max. 100 audio channels) for most audio drivers
237        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
238          opposed to the LSCP specs
239        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
240          reflected the wrong value
241        - fixed a memory management bug in ASIO driver
242        - Makefile fix: JACK_CFLAGS wasn't used
243        - JACK: use jack_client_open instead of the deprecated
244          jack_client_new
245        - added (experimental) CoreAudio driver
246        - applied old fixes to the ASIO driver that were included in the
247          previous binary release but accidentally never committed to CVS
248          (fixes #117)
249        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
250          win64)
251        - VST: added support for sample rate and buffer size changes
252        - VST: close editor (Fantasia) when the VST is removed
253        - VST: avoid opening Fantasia more than once for each VST instance
254        - VST: export main function as "main" on Linux too (fix for
255          energyXT)
256        - VST: changed number of output channels from one stereo to 16
257          stereo
258        - added channel routing, fxsends and midi maps to the settings
259          stored in the plugin state
260        - performance optimization of AudioChannel::MixTo() and
261          AudioChannel::CopyTo() methods using GCC vector exensions
262          (if available)
263        - ASIO fixes: avoid initializing the device twice, avoid throwing
264          exception when getting parameters from a disconnected device
265    
266      * MIDI driver:
267        - added JACK MIDI driver
268        - dispatch bank select as ordinary CC as well, the user might seriously
269          want to (mis)use it for some purpose ("fixed" in all current MIDI
270          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
271        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
272          CoreMidi or AU
273        - fixed mingw-w64 compilation error in MME driver
274        - made program change handling in MIDI thread real-time safe by
275          moving the logic to a non-RT thread
276        - fixed minor memory leak in ALSA driver
277    
278      * instruments database:
279        - avoid time consuming samples scanning when adding instruments
280          to the instruments database
281        - added support for handling lost files in the instruments database
282        - Implemented option for adding instruments in separate directories
283          in the instruments database
284          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
285        - work-around for missing fnmatch function on Windows to make
286          instrument database compilable
287        - added instrument database support on Windows
288          works with both standalone mode and VST plugin.
289          the instruments DB file is located in
290          %USERPROFILE%\.linuxsampler\instruments.db which allows different
291          databases for each windows user
292          if no DB is present it automatically creates the .linuxsampler subdir
293          and then creates an empty DB
294        - fixed recursive import, which was broken on Windows
295    
296      * Gigasampler format engine:
297        - fixed a memory leak that could happen when a channel was deleted
298          while notes were playing
299        - made it possible to load an instrument even if the audio thread
300          isn't running
301        - added partial support for the "Controller Triggered" MIDI rule,
302          enough for piano gigs with pedal noise samples
303        - minor fix: only mark FX sends as being modified if really the
304          respective FX send MIDI controller was used
305        - added support for GM global device volume SysEx message
306          (can be selected at compile time to either apply globally to the
307          whole sampler [default] or only to the sampler channels that are
308          connected to the respective MIDI input port the SysEx message arrived
309          on)
310        - bugfix: notes triggered at position 0 in the audio buffer were
311          sometimes wrongly killed in the same buffer, causing no sound to
312          be played
313        - added support for chromatic / drumkit mode Roland GS Sysex message
314          which is usally used to switch a part between chromatic sounds and
315          drumkit sounds (as opposed to their common default setting of MIDI
316          part 10 being a drumkit part and all other ones chromatic parts), in
317          LS however one can switch between the first 16 MIDI instrument maps
318          defined for the sampler
319        - made it possible to create multiple sample channels even if the
320          audio thread isn't running
321        - fixed crash when removing channel with active voices (#116)
322        - bugfix: on sample reference changes (instrument editor), only
323          un-cache the respective sample if it's really not used by any
324          sampler engine anymore
325        - re-cache samples in case they were changed by an instrument editor,
326          e.g. when a sample was added while playing (#82)
327        - fixed hanging notes which occured when note-off event had the exact
328          same time stamp as the voice's note-on event and occured both in the
329          same audio fragment cycle (fixes bug #112)
330        - added support for the "fine tune" and "pitch bend range"
331          instrument-level gig parameters
332        - fixed minor artifacts in pitch bend handling
333        - added support for GS Reset SysEx message
334        - allow gig files to use unlimited downward pitch shifting
335        - added a limit check for upward pitch shifting
336        - bugfix: sometimes, when playing a note twice fast, the second
337          note was silent
338        - fixed crash happening when a pitch bend event arrived at the
339          same time a new instrument was loading
340    
341      * LSCP server:
342        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
343          react on MIDI data arriving on certain sampler channels (so far only
344          Note-On and Note-Off events are sent via this LSCP event)
345        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
346          react on MIDI data arriving on certain MIDI input devices (so far only
347          Note-On and Note-Off events are sent via this LSCP event)
348        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
349          SET DB_INSTRUMENT FILE_PATH
350        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
351          frontends to send MIDI messages to specific sampler channel
352        - added two additional fields to GET FILE INSTRUMENT INFO command -
353          KEY_BINDINGS and KEYSWITCH_BINDINGS
354        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
355          was incorrect
356        - Optimized the retrieval of the MIDI instrument mappings
357        - added new LSCP command "SET VOICES" to globally alter the maximum
358          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
359          be triggered respectively
360        - added new LSCP command "SET STREAMS" to globally alter the maximum
361          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
362          which will be triggered respectively
363        - bugfix: retry if "select" returns EINTR (this fixes a crash when
364          a gigedit file dialog is opened)
365        - close all connections when LSCPServer is deleted
366        - hard close of all sockets on exit
367        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
368          driver
369    
370      * Bug fixes:
371        - fixed a crash which occurs when removing a sampler channel waiting
372          to start instrument loading after another channel
373        - fixed a crash which occurs when removing a sampler channel with
374          instrument loading in progress (bug #113)
375        - fixed termination caused by uncaught exception when adding MIDI
376          instrument with PERSISTENT load mode
377        - fixed possible iterator invalidations when resetting the sampler
378        - fixed memory leaks when issuing the following LSCP commands:
379          GET AUDIO_OUTPUT_DRIVER INFO
380          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
381          GET MIDI_INPUT_DRIVER INFO
382          GET MIDI_INPUT_DRIVER_PARAMETER INFO
383        - fixed possible compilation error when sqlite is not present
384        - fixed orphaned pointers when setting maximum voices limit (bug #118)
385        - fixed crash when changing the audio output device of a sampler
386          channel with loaded instrument and start playing notes
387        - fixed endless loop in Engine::SuspendAll() (bug #120)
388        - fixed a low-level atomic load function that was broken on 64-bit
389          PowerPC, which probably could cause crashes on that platform
390        - fixed a memory management error which could cause a crash when a
391          plugin was unloaded
392        - bugfix: two private structs had the same name, which could cause
393          problems if the linker chose the wrong constructor

409        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
410          out all the space. operator--() did not apply size_mask after
411          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
412          order to avoid problems with the _NonVolatileReader functions.
413        - bugfix: Stream.h: added a missing divide by BytesPerSample in
414          GetWriteSpace(). Since this function is currently only used in
415          the stream's qsort() compare function, it didn't trigger any
416          bugs.
417        - Resampler.h, Synthesizer.h: cubic interpolation now works in
418          24bit mode too. Faster method to read 24bit words on little
419          endian machines (x86): replaced 3 byte reads + shifts with a 1
420          unaligned 32bit read and shift
421        - experimental support for MS Windows (MIDI input via MME, AUDIO
422          output via ASIO)
423        - made handling of SIGINT signal (Ctrl-C) a bit more robust
424        - support for monitoring the total number of active disk streams
425          (new LSCP commands: GET TOTAL_STREAM_COUNT,
426          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
427    
428      * AUDIO driver:
429        - added Windows ASIO low latency audio driver
430    
431      * MIDI driver:
432        - added MME Windows MIDI driver
433    
434      * LSCP server:
435        - added support for Windows style path / filenames, however with
436          forward slash path separators instead of backslash
437          (i.e. "C:/foo/bar.gig")
438        - allow naughty liblscp to send non-string device parameters within
439          apostrophes as well
440        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
441          "LIST FILE INSTRUMENTS <file>" and
442          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
443          about an arbitrary instrument file on the system where the sampler is
444          running on
