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

72        - improved logic for sw_lokey/hikey/up/down/last
73        - added more v1 aliases to parser
74        - reduced memory usage for sfz data
75        - RT-safeness: avoid malloc in audio thread
76        - fixed a bug that could cause voice stealing to fail
77        - optimized sample lookup
78        - improved support for exclusive groups (group, off_by and
79          off_mode)
80        - added support for controller triggered regions (on_locc/on_hicc)
81        - added support for loop_mode=one_shot
82        - fixed playback of 16 bit wav files on big endian CPUs
83        - added support for Ogg Vorbis sample files
84        - use loop markers from sample file if loop_start and loop_end are
85          not set in sfz file
86        - implemeted filters. Filter types: lowpass, bandpass, bandreject
87          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
88          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
89          cutoff_cc, cutoff_chanaft.
90        - bugfix: zero ampeg_sustain didn't work
91        - added support for velocity effect on amplifier envelope time
92          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
93          ampeg_vel2release)
94        - added support for EG hold (ampeg_hold)

98        - RT-safeness: avoid malloc in audio thread
99        - fixed a bug that could cause voice stealing to fail
100        - fine-tuned amplitude EG (by switching from gig to sfz EG)
101    
102      * Gigasampler format engine:
103        - bugfix: pitch LFO controller "internal+aftertouch" was broken
104        - bugfix: filter keyboard tracking was broken
105        - filter performance fix (an unnecessary copy was made of the
106          filter parameters in each sub fragment)
107    
108      * Host plugins:
109        - AU bugfix: failed to destroy its audio/MIDI devices
110        - Listen to all interfaces on Mac OS X (INADDR_ANY)
111        - VST bugfix: If the host called resume() before and after
112          changing sample rate or block size, the number of channels was
113          incorrectly set to two. This caused silence in Cubase 5.
114        - save engine type (gig, sfz or sf2) in plugin state
115        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
116          64 bit Windows
117        - AU: changed number of output channels from one stereo to 16
118          stereo
119        - VST: made it possible to build the VST plugin for Mac
120        - AU: link AU plugin dynamically if --disable-shared isn't
121          specified
122    
123      * MIDI driver:
124        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
125          the ALSA sequencer client name
126        - removed limit of maximum amount of MIDI ports per MIDI device, since
127          there is no reason for this limit
128    
129      * audio driver:
130        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
131    
132      * LSCP server:
133        - added support for sending MIDI CC messages via LSCP command
134          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

155          "GET SEND_EFFECT_CHAIN INFO <audio-device> <effect-chain>"
156        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>
157          <effect-chain> <effect-instance>"
158        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
159          <effect-chain> <effect-chain-pos> <effect-instance>"

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