1  Version CVS HEAD (?)  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    
9      * general changes:
10        - Refactoring: moved the independent code from
11          the Gigasampler format engine to base classes
12        - command line option '--profile' is currently disabled, since the
13          respective profiling code is currently broken
14        - Introduced support for optional environment variable
15          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
16          where the sampler shall look for instrument editor plugins
17          (patch by Luis Garrido, slightly modified).
18        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21          note (in this implementation of the sampler its simply hard routed to
22          the 1st effect send of the sampler channel, no matter what the actual
23          effect type is)
24        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25          note (in this implementation of the sampler its simply hard routed to
26          the 2nd effect send of the sampler channel, no matter what the actual
27          effect type is)
28        - implemented support for internal LADSPA effects
29        - raised limit of program change queue from 100 to 512
30          (as suggested by Alex Stone)
31    
32      * Gigasampler format engine:
33        - implemented the "round robin keyboard" dimension
34        - fixed round robin and random dimensions for cases when number of
35          dimension zones is not a power of two
36        - made round robin use a counter for each region instead of each
37          key
38    
39      * SFZ format engine:
40        - Initial implementation (not usable yet)
41        - added support for v2 multiple stage envelope generators
42        - added a fine-tuned v1 envelope generator instead of using the
43          one from the gig engine
44        - fixed memory leak and memory handling errors
45        - added support for trigger=first, trigger=legato and sw_previous
46        - allow non-numerical key values ("C#4" for example)
47        - "key" opcode now sets pitch_keycenter too
48        - fixed error when unloading instrument with same sample used by
49          multiple regions
50        - added some opcode aliases, like loopmode for loop_mode, to be
51          more compatible
52        - added support for trigger=release and rt_decay
53        - added support for off_mode=normal
54        - added support for random, seq_position, seq_length and volume
55        - added v1 LFO opcodes to parser (no support in engine yet)
56        - added support for amp_veltrack and amp_velcurve_N
57        - fine-tuned the default velocity curve
58        - added support for transpose
59        - fixed crash when using sw_down/up
60        - improved logic for sw_lokey/hikey/up/down/last
61        - added more v1 aliases to parser
62        - reduced memory usage for sfz data
63        - RT-safeness: avoid malloc in audio thread
64        - fixed a bug that could cause voice stealing to fail
65        - optimized sample lookup
66        - improved support for exclusive groups (group, off_by and
67          off_mode)
68        - added support for controller triggered regions (on_locc/on_hicc)
69        - added support for loop_mode=one_shot
70        - fixed playback of 16 bit wav files on big endian CPUs
71        - added support for Ogg Vorbis sample files
72        - use loop markers from sample file if loop_start and loop_end are
73          not set in sfz file
74        - implemeted filters. Filter types: lowpass, bandpass, bandreject
75          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
76          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
77          cutoff_cc, cutoff_chanaft.
78        - bugfix: zero ampeg_sustain didn't work
79        - added support for velocity effect on amplifier envelope time
80          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
81          ampeg_vel2release)
82    
83      * SoundFont format engine:
84        - Initial implementation (not usable yet)
85        - RT-safeness: avoid malloc in audio thread
86        - fixed a bug that could cause voice stealing to fail
87    
88      * Gigasampler format engine:
89        - bugfix: pitch LFO controller "internal+aftertouch" was broken
90        - bugfix: filter keyboard tracking was broken
91        - filter performance fix (an unnecessary copy was made of the
92          filter parameters in each sub fragment)
93    
94      * Host plugins:
95        - AU bugfix: failed to destroy its audio/MIDI devices
96        - Listen to all interfaces on Mac OS X (INADDR_ANY)
97        - VST bugfix: If the host called resume() before and after
98          changing sample rate or block size, the number of channels was
99          incorrectly set to two. This caused silence in Cubase 5.
100        - save engine type (gig, sfz or sf2) in plugin state
101        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
102          64 bit Windows
103    
104      * MIDI driver:
105        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
106          the ALSA sequencer client name
107        - removed limit of maximum amount of MIDI ports per MIDI device, since
108          there is no reason for this limit
109    
110      * audio driver:
111        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
112

139        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
140          <effect-chain> <effect-chain-pos> <effect-instance>"
141        - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>
142          <effect-chain> <chain-pos>"
143        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
144          <fx_send_id> <effect_chain> <chain_pos>"
145        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
146    
147      * Bug fixes:
148        - Fixed crash which may occur when MIDI key + transpose is out of range
149        - minor valgrind fixes
150        - fixed crash which occured when changing an already deployed sampler
151          channel to a different engine type
152        - fixed crash when deleting a sampler channel or changing engine
153          type while an instrument load was in progress
154        - bugfix: playing a note while changing the instrument could cause
155          a crash, or give "Handing back unknown region" error messages
156        - bugfix: calling SET VOICES (which Fantasia does on start and
157          refresh) could cause instruments to be unloaded
158    
159    Version 1.0.0 (31 July 2009)
160    
161      * packaging changes:
162        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
163          causing e.g. the libgig test to fail when
164          "./configure --disable-jack-driver" was used
165          (patch by Alexis Ballier)
166        - fixed compilation with gcc 4.3
167        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
168        - fixed configure so it detects x86_64 (#107)
169        - fixes for building with newer MinGW versions
170        - fix for building with bison 2.4 (#111)
171        - fixed building with libgig installed in a non-standard directory
172        - minor fix in configure for mmsystem.h detection on MinGW
173        - Windows: look for editor plugins and Fantasia using base
174          directory of liblinuxsampler dll (look in the same directory and one
175          directory above)
176        - configure script fix: removed unconditional use of SSE
177        - fixed building with sqlite installed in a non-standard directory
178        - when cross-compiling, don't try to create instruments.db
179        - fix for new mingw-w64 version, which has usleep
180    
181      * general changes:
182        - bugfix: on some POSIX systems instrument editor plugins refused to
183          load as we used a non-portable Linux specific struct field
184          (fixes bug #70, patch by Ronald Baljeu)
185        - fixed endless loop which occured when loading an instrument editor
186          plugin DLL on Windows systems failed
187        - fixed memory leaks that occurred when liblinuxsampler was unloaded
188        - optimized the SynchronizedConfig class so it doesn't wait
189          unnecessarily long after an update
190        - added support for notifying instrument editors on note-on / note-off
191          events (e.g. to highlight the pressed keys on the virtual keyboard
192          of gigedit)
193        - added support for triggering notes by instrument editors (see above)
194        - be verbose on DLL load errors (on Linux)
195        - fixed di-harmonic triangle LFO implementation (this LFO implementation
196          is only used by very few systems, most pick the int math
197          implementation, which is usually faster)
198        - fixes for audio drivers with varying buffer sizes
199        - experimental support for running LinuxSampler as a DSSI, LV2 and
200          VST plugin
201        - notification events for stream/voice count statistics are now sent
202          only when there are actual changes
203        - added memory ordering constraints to improve stability on
204          multi-core and multi-cpu systems
205        - maximum voices and disk streams can now be altered at runtime
206        - fixed CPU feature detection on x86_64 (maybe fixes #108)
207        - automatic stacktrace mechanism is now turned off by default and can
208          be switched on by command line option "--stacktrace" (the automatic
209          stacktrace mechanism seems to be broken on most systems at the moment)
210        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
211          a pointer to the launched InstrumentEditor object
212        - added optional 3rd party user data parameter for following
213          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
214          InstrumentEditor::Launch(),
215          InstrumentManager::LaunchInstrumentEditor()
216        - theoretical fix: made SynchronizedConfig follow C++0x memory
217          model more strictly
218        - fixes for using large audio device buffers
219        - Windows: add the installation directory to the DLL search path
220          when loading an editor plugin (solves problems with VST and
221          gigedit on systems with other GTK versions installed)
222    
223      * audio driver:
224        - removed the nonsense audio channel constraint (which was hard coded to
225          max. 100 audio channels) for most audio drivers
226        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
227          opposed to the LSCP specs
228        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
229          reflected the wrong value
230        - fixed a memory management bug in ASIO driver
231        - Makefile fix: JACK_CFLAGS wasn't used
232        - JACK: use jack_client_open instead of the deprecated
233          jack_client_new
234        - added (experimental) CoreAudio driver
235        - applied old fixes to the ASIO driver that were included in the
236          previous binary release but accidentally never committed to CVS
237          (fixes #117)
238        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
239          win64)
240        - VST: added support for sample rate and buffer size changes
241        - VST: close editor (Fantasia) when the VST is removed
242        - VST: avoid opening Fantasia more than once for each VST instance
243        - VST: export main function as "main" on Linux too (fix for
244          energyXT)
245        - VST: changed number of output channels from one stereo to 16
246          stereo
247        - added channel routing, fxsends and midi maps to the settings
248          stored in the plugin state
249        - performance optimization of AudioChannel::MixTo() and
250          AudioChannel::CopyTo() methods using GCC vector exensions
251          (if available)
252        - ASIO fixes: avoid initializing the device twice, avoid throwing
253          exception when getting parameters from a disconnected device
254    
255      * MIDI driver:
256        - added JACK MIDI driver
257        - dispatch bank select as ordinary CC as well, the user might seriously
258          want to (mis)use it for some purpose ("fixed" in all current MIDI
259          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
260        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
261          CoreMidi or AU
262        - fixed mingw-w64 compilation error in MME driver
263        - made program change handling in MIDI thread real-time safe by
264          moving the logic to a non-RT thread
265        - fixed minor memory leak in ALSA driver
266    
267      * instruments database:
268        - avoid time consuming samples scanning when adding instruments
269          to the instruments database
270        - added support for handling lost files in the instruments database
271        - Implemented option for adding instruments in separate directories
272          in the instruments database
273          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
274        - work-around for missing fnmatch function on Windows to make
275          instrument database compilable
276        - added instrument database support on Windows
277          works with both standalone mode and VST plugin.
278          the instruments DB file is located in
279          %USERPROFILE%\.linuxsampler\instruments.db which allows different
280          databases for each windows user
281          if no DB is present it automatically creates the .linuxsampler subdir
282          and then creates an empty DB
283        - fixed recursive import, which was broken on Windows
284    
285      * Gigasampler format engine:
286        - fixed a memory leak that could happen when a channel was deleted
287          while notes were playing
288        - made it possible to load an instrument even if the audio thread
289          isn't running
290        - added partial support for the "Controller Triggered" MIDI rule,
291          enough for piano gigs with pedal noise samples
292        - minor fix: only mark FX sends as being modified if really the
293          respective FX send MIDI controller was used
294        - added support for GM global device volume SysEx message
295          (can be selected at compile time to either apply globally to the
296          whole sampler [default] or only to the sampler channels that are
297          connected to the respective MIDI input port the SysEx message arrived
298          on)
299        - bugfix: notes triggered at position 0 in the audio buffer were
300          sometimes wrongly killed in the same buffer, causing no sound to
301          be played
302        - added support for chromatic / drumkit mode Roland GS Sysex message
303          which is usally used to switch a part between chromatic sounds and
304          drumkit sounds (as opposed to their common default setting of MIDI
305          part 10 being a drumkit part and all other ones chromatic parts), in
306          LS however one can switch between the first 16 MIDI instrument maps
307          defined for the sampler
308        - made it possible to create multiple sample channels even if the
309          audio thread isn't running
310        - fixed crash when removing channel with active voices (#116)
311        - bugfix: on sample reference changes (instrument editor), only
312          un-cache the respective sample if it's really not used by any
313          sampler engine anymore
314        - re-cache samples in case they were changed by an instrument editor,
315          e.g. when a sample was added while playing (#82)
316        - fixed hanging notes which occured when note-off event had the exact
317          same time stamp as the voice's note-on event and occured both in the
318          same audio fragment cycle (fixes bug #112)
319        - added support for the "fine tune" and "pitch bend range"
320          instrument-level gig parameters
321        - fixed minor artifacts in pitch bend handling
322        - added support for GS Reset SysEx message
323        - allow gig files to use unlimited downward pitch shifting
324        - added a limit check for upward pitch shifting
325        - bugfix: sometimes, when playing a note twice fast, the second
326          note was silent
327        - fixed crash happening when a pitch bend event arrived at the
328          same time a new instrument was loading
329    
330      * LSCP server:
331        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
332          react on MIDI data arriving on certain sampler channels (so far only
333          Note-On and Note-Off events are sent via this LSCP event)
334        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
335          react on MIDI data arriving on certain MIDI input devices (so far only
336          Note-On and Note-Off events are sent via this LSCP event)
337        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
338          SET DB_INSTRUMENT FILE_PATH
339        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
340          frontends to send MIDI messages to specific sampler channel
341        - added two additional fields to GET FILE INSTRUMENT INFO command -
342          KEY_BINDINGS and KEYSWITCH_BINDINGS
343        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
344          was incorrect
345        - Optimized the retrieval of the MIDI instrument mappings
346        - added new LSCP command "SET VOICES" to globally alter the maximum
347          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
348          be triggered respectively
349        - added new LSCP command "SET STREAMS" to globally alter the maximum
350          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
351          which will be triggered respectively
352        - bugfix: retry if "select" returns EINTR (this fixes a crash when
353          a gigedit file dialog is opened)
354        - close all connections when LSCPServer is deleted
355        - hard close of all sockets on exit
356        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
357          driver
358    
359      * Bug fixes:
360        - fixed a crash which occurs when removing a sampler channel waiting
361          to start instrument loading after another channel
362        - fixed a crash which occurs when removing a sampler channel with
363          instrument loading in progress (bug #113)
364        - fixed termination caused by uncaught exception when adding MIDI
365          instrument with PERSISTENT load mode
366        - fixed possible iterator invalidations when resetting the sampler
367        - fixed memory leaks when issuing the following LSCP commands:
368          GET AUDIO_OUTPUT_DRIVER INFO
369          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
370          GET MIDI_INPUT_DRIVER INFO
371          GET MIDI_INPUT_DRIVER_PARAMETER INFO
372        - fixed possible compilation error when sqlite is not present
373        - fixed orphaned pointers when setting maximum voices limit (bug #118)
374        - fixed crash when changing the audio output device of a sampler
375          channel with loaded instrument and start playing notes
376        - fixed endless loop in Engine::SuspendAll() (bug #120)
377        - fixed a low-level atomic load function that was broken on 64-bit
378          PowerPC, which probably could cause crashes on that platform
379        - fixed a memory management error which could cause a crash when a
380          plugin was unloaded
381        - bugfix: two private structs had the same name, which could cause
382          problems if the linker chose the wrong constructor
383        - fixed low-level ConditionServer usage bug that caused lockups on
384          Windows
385
