1    Version CVS HEAD (?)
2    
3      * packaging changes:
4        - fixed building with newer MinGW-w64
5    
6      * general changes:
7        - Refactoring: moved the independent code from
8          the Gigasampler format engine to base classes
9        - command line option '--profile' is currently disabled, since the
10          respective profiling code is currently broken
11        - Introduced support for optional environment variable
12          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13          where the sampler shall look for instrument editor plugins
14          (patch by Luis Garrido, slightly modified).
15        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18          note (in this implementation of the sampler its simply hard routed to
19          the 1st effect send of the sampler channel, no matter what the actual
20          effect type is)
21        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22          note (in this implementation of the sampler its simply hard routed to
23          the 2nd effect send of the sampler channel, no matter what the actual
24          effect type is)
25        - implemented support for internal LADSPA effects
26        - raised limit of program change queue from 100 to 512
27          (as suggested by Alex Stone)
28    
29      * Gigasampler format engine:
30        - implemented the "round robin keyboard" dimension
31        - fixed round robin and random dimensions for cases when number of
32          dimension zones is not a power of two
33        - made round robin use a counter for each region instead of each
34          key
35    
36      * SFZ format engine:
37        - Initial implementation (not usable yet)
38        - added support for v2 multiple stage envelope generators
39        - added a fine-tuned v1 envelope generator instead of using the
40          one from the gig engine
41        - fixed memory leak and memory handling errors
42        - added support for trigger=first, trigger=legato and sw_previous
43        - allow non-numerical key values ("C#4" for example)
44        - "key" opcode now sets pitch_keycenter too
45        - fixed error when unloading instrument with same sample used by
46          multiple regions
47        - added some opcode aliases, like loopmode for loop_mode, to be
48          more compatible
49        - added support for trigger=release and rt_decay
50        - added support for off_mode=normal
51        - added support for random, seq_position, seq_length and volume
52        - added v1 LFO opcodes to parser (no support in engine yet)
53        - added support for amp_veltrack and amp_velcurve_N
54        - fine-tuned the default velocity curve
55        - added support for transpose
56        - fixed crash when using sw_down/up
57        - improved logic for sw_lokey/hikey/up/down/last
58        - added more v1 aliases to parser
59        - reduced memory usage for sfz data
60        - RT-safeness: avoid malloc in audio thread
61        - fixed a bug that could cause voice stealing to fail
62        - optimized sample lookup
63        - improved support for exclusive groups (group, off_by and
64          off_mode)
65        - added support for controller triggered regions (on_locc/on_hicc)
66        - added support for loop_mode=one_shot
67        - fixed playback of 16 bit wav files on big endian CPUs
68        - added support for Ogg Vorbis sample files
69    
70      * SoundFont format engine:
71        - Initial implementation (not usable yet)
72        - RT-safeness: avoid malloc in audio thread
73        - fixed a bug that could cause voice stealing to fail
74    
75      * Host plugins:
76        - AU bugfix: failed to destroy its audio/MIDI devices
77        - Listen to all interfaces on Mac OS X (INADDR_ANY)
78        - VST bugfix: If the host called resume() before and after
79          changing sample rate or block size, the number of channels was
80          incorrectly set to two. This caused silence in Cubase 5.
81    
82      * MIDI driver:
83        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
84          the ALSA sequencer client name
85        - removed limit of maximum amount of MIDI ports per MIDI device, since
86          there is no reason for this limit
87    
88      * LSCP server:
89        - added support for sending MIDI CC messages via LSCP command
90          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

103        - added LSCP command "SET EFFECT_INSTANCE_INPUT_CONTROL VALUE
104          <effect-instance> <input-control> <value>"
105        - added LSCP command "GET SEND_EFFECT_CHAINS <audio-device>"
106        - added LSCP command "LIST SEND_EFFECT_CHAINS <audio-device>"
107        - added LSCP command "ADD SEND_EFFECT_CHAIN <audio-device>"

117          <effect-chain> <chain-pos>"
118        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
119          <fx_send_id> <effect_chain> <chain_pos>"
120        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
121    
122      * Bug fixes:
123        - Fixed crash which may occur when MIDI key + transpose is out of range
124        - minor valgrind fixes
125        - fixed crash which occured when changing an already deployed sampler
126          channel to a different engine type
127        - fixed crash when deleting a sampler channel or changing engine
128          type while an instrument load was in progress
129    
130    Version 1.0.0 (31 July 2009)
131    
132      * packaging changes:
133        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
134          causing e.g. the libgig test to fail when
135          "./configure --disable-jack-driver" was used
136          (patch by Alexis Ballier)
137        - fixed compilation with gcc 4.3
138        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
139        - fixed configure so it detects x86_64 (#107)
140        - fixes for building with newer MinGW versions
141        - fix for building with bison 2.4 (#111)
142        - fixed building with libgig installed in a non-standard directory
143        - minor fix in configure for mmsystem.h detection on MinGW
144        - Windows: look for editor plugins and Fantasia using base
145          directory of liblinuxsampler dll (look in the same directory and one
146          directory above)
147        - configure script fix: removed unconditional use of SSE
148        - fixed building with sqlite installed in a non-standard directory
149        - when cross-compiling, don't try to create instruments.db
150        - fix for new mingw-w64 version, which has usleep
151    
152      * general changes:
153        - bugfix: on some POSIX systems instrument editor plugins refused to
154          load as we used a non-portable Linux specific struct field
155          (fixes bug #70, patch by Ronald Baljeu)
156        - fixed endless loop which occured when loading an instrument editor
157          plugin DLL on Windows systems failed
158        - fixed memory leaks that occurred when liblinuxsampler was unloaded
159        - optimized the SynchronizedConfig class so it doesn't wait
160          unnecessarily long after an update
161        - added support for notifying instrument editors on note-on / note-off
162          events (e.g. to highlight the pressed keys on the virtual keyboard
163          of gigedit)
164        - added support for triggering notes by instrument editors (see above)
165        - be verbose on DLL load errors (on Linux)
166        - fixed di-harmonic triangle LFO implementation (this LFO implementation
167          is only used by very few systems, most pick the int math
168          implementation, which is usually faster)
169        - fixes for audio drivers with varying buffer sizes
170        - experimental support for running LinuxSampler as a DSSI, LV2 and
171          VST plugin
172        - notification events for stream/voice count statistics are now sent
173          only when there are actual changes
174        - added memory ordering constraints to improve stability on
175          multi-core and multi-cpu systems
176        - maximum voices and disk streams can now be altered at runtime
177        - fixed CPU feature detection on x86_64 (maybe fixes #108)
178        - automatic stacktrace mechanism is now turned off by default and can
179          be switched on by command line option "--stacktrace" (the automatic
180          stacktrace mechanism seems to be broken on most systems at the moment)
181        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
182          a pointer to the launched InstrumentEditor object
183        - added optional 3rd party user data parameter for following
184          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
185          InstrumentEditor::Launch(),
186          InstrumentManager::LaunchInstrumentEditor()
187        - theoretical fix: made SynchronizedConfig follow C++0x memory
188          model more strictly
189        - fixes for using large audio device buffers
190        - Windows: add the installation directory to the DLL search path
191          when loading an editor plugin (solves problems with VST and
192          gigedit on systems with other GTK versions installed)
193    
194      * audio driver:
195        - removed the nonsense audio channel constraint (which was hard coded to
196          max. 100 audio channels) for most audio drivers
197        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
198          opposed to the LSCP specs
199        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
200          reflected the wrong value
201        - fixed a memory management bug in ASIO driver
202        - Makefile fix: JACK_CFLAGS wasn't used
203        - JACK: use jack_client_open instead of the deprecated
204          jack_client_new
205        - added (experimental) CoreAudio driver
206        - applied old fixes to the ASIO driver that were included in the
207          previous binary release but accidentally never committed to CVS
208          (fixes #117)
209        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
210          win64)
211        - VST: added support for sample rate and buffer size changes
212        - VST: close editor (Fantasia) when the VST is removed
213        - VST: avoid opening Fantasia more than once for each VST instance
214        - VST: export main function as "main" on Linux too (fix for
215          energyXT)
216        - VST: changed number of output channels from one stereo to 16
217          stereo
218        - added channel routing, fxsends and midi maps to the settings
219          stored in the plugin state
220        - performance optimization of AudioChannel::MixTo() and
221          AudioChannel::CopyTo() methods using GCC vector exensions
222          (if available)
223        - ASIO fixes: avoid initializing the device twice, avoid throwing
224          exception when getting parameters from a disconnected device
225    
226      * MIDI driver:
227        - added JACK MIDI driver
228        - dispatch bank select as ordinary CC as well, the user might seriously
229          want to (mis)use it for some purpose ("fixed" in all current MIDI
230          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
231        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
232          CoreMidi or AU
233        - fixed mingw-w64 compilation error in MME driver
234        - made program change handling in MIDI thread real-time safe by
235          moving the logic to a non-RT thread
236        - fixed minor memory leak in ALSA driver
237    
238      * instruments database:
239        - avoid time consuming samples scanning when adding instruments
240          to the instruments database
241        - added support for handling lost files in the instruments database
242        - Implemented option for adding instruments in separate directories
243          in the instruments database
244          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
245        - work-around for missing fnmatch function on Windows to make
246          instrument database compilable
247        - added instrument database support on Windows
248          works with both standalone mode and VST plugin.
249          the instruments DB file is located in
250          %USERPROFILE%\.linuxsampler\instruments.db which allows different
251          databases for each windows user
252          if no DB is present it automatically creates the .linuxsampler subdir
253          and then creates an empty DB
254        - fixed recursive import, which was broken on Windows
255    
256      * Gigasampler format engine:
257        - fixed a memory leak that could happen when a channel was deleted
258          while notes were playing
259        - made it possible to load an instrument even if the audio thread
260          isn't running
261        - added partial support for the "Controller Triggered" MIDI rule,
262          enough for piano gigs with pedal noise samples
263        - minor fix: only mark FX sends as being modified if really the
264          respective FX send MIDI controller was used
265        - added support for GM global device volume SysEx message
266          (can be selected at compile time to either apply globally to the
267          whole sampler [default] or only to the sampler channels that are
268          connected to the respective MIDI input port the SysEx message arrived
269          on)
270        - bugfix: notes triggered at position 0 in the audio buffer were
271          sometimes wrongly killed in the same buffer, causing no sound to
272          be played
273        - added support for chromatic / drumkit mode Roland GS Sysex message
274          which is usally used to switch a part between chromatic sounds and
275          drumkit sounds (as opposed to their common default setting of MIDI
276          part 10 being a drumkit part and all other ones chromatic parts), in
277          LS however one can switch between the first 16 MIDI instrument maps
278          defined for the sampler
279        - made it possible to create multiple sample channels even if the
280          audio thread isn't running
281        - fixed crash when removing channel with active voices (#116)
282        - bugfix: on sample reference changes (instrument editor), only
283          un-cache the respective sample if it's really not used by any
284          sampler engine anymore
285        - re-cache samples in case they were changed by an instrument editor,
286          e.g. when a sample was added while playing (#82)
287        - fixed hanging notes which occured when note-off event had the exact
288          same time stamp as the voice's note-on event and occured both in the
289          same audio fragment cycle (fixes bug #112)
290        - added support for the "fine tune" and "pitch bend range"
291          instrument-level gig parameters
292        - fixed minor artifacts in pitch bend handling
293        - added support for GS Reset SysEx message
294        - allow gig files to use unlimited downward pitch shifting
295        - added a limit check for upward pitch shifting
296        - bugfix: sometimes, when playing a note twice fast, the second
297          note was silent
298        - fixed crash happening when a pitch bend event arrived at the
299          same time a new instrument was loading
300    
301      * LSCP server:
302        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
303          react on MIDI data arriving on certain sampler channels (so far only
304          Note-On and Note-Off events are sent via this LSCP event)
305        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
306          react on MIDI data arriving on certain MIDI input devices (so far only
307          Note-On and Note-Off events are sent via this LSCP event)
308        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
309          SET DB_INSTRUMENT FILE_PATH
310        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
311          frontends to send MIDI messages to specific sampler channel
312        - added two additional fields to GET FILE INSTRUMENT INFO command -
313          KEY_BINDINGS and KEYSWITCH_BINDINGS
314        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
315          was incorrect
316        - Optimized the retrieval of the MIDI instrument mappings
317        - added new LSCP command "SET VOICES" to globally alter the maximum
318          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
319          be triggered respectively
320        - added new LSCP command "SET STREAMS" to globally alter the maximum
321          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
322          which will be triggered respectively
323        - bugfix: retry if "select" returns EINTR (this fixes a crash when
324          a gigedit file dialog is opened)
325        - close all connections when LSCPServer is deleted
326        - hard close of all sockets on exit
327        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
328          driver
329    
330      * Bug fixes:
331        - fixed a crash which occurs when removing a sampler channel waiting
332          to start instrument loading after another channel
333        - fixed a crash which occurs when removing a sampler channel with
334          instrument loading in progress (bug #113)
335        - fixed termination caused by uncaught exception when adding MIDI
336          instrument with PERSISTENT load mode
337        - fixed possible iterator invalidations when resetting the sampler
338        - fixed memory leaks when issuing the following LSCP commands:
339          GET AUDIO_OUTPUT_DRIVER INFO
340          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
341          GET MIDI_INPUT_DRIVER INFO
342          GET MIDI_INPUT_DRIVER_PARAMETER INFO
343        - fixed possible compilation error when sqlite is not present
344        - fixed orphaned pointers when setting maximum voices limit (bug #118)
345        - fixed crash when changing the audio output device of a sampler
346          channel with loaded instrument and start playing notes
347        - fixed endless loop in Engine::SuspendAll() (bug #120)
348        - fixed a low-level atomic load function that was broken on 64-bit
349          PowerPC, which probably could cause crashes on that platform
350        - fixed a memory management error which could cause a crash when a
351          plugin was unloaded
352        - bugfix: two private structs had the same name, which could cause
353          problems if the linker chose the wrong constructor
354        - fixed low-level ConditionServer usage bug that caused lockups on
355          Windows
