# Line 1  Line 1 
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    
27      * Gigasampler format engine:
28        - implemented the "round robin keyboard" dimension
29        - fixed round robin and random dimensions for cases when number of
30          dimension zones is not a power of two
31        - made round robin use a counter for each region instead of each
32          key
33    
34      * SFZ format engine:
35        - Initial implementation (not usable yet)
36        - added support for v2 multiple stage envelope generators
37        - added a fine-tuned v1 envelope generator instead of using the
38          one from the gig engine
39        - fixed memory leak and memory handling errors
40        - added support for trigger=first, trigger=legato and sw_previous
41        - allow non-numerical key values ("C#4" for example)
42        - "key" opcode now sets pitch_keycenter too
43        - fixed error when unloading instrument with same sample used by
44          multiple regions
45        - added some opcode aliases, like loopmode for loop_mode, to be
46          more compatible
47        - added support for trigger=release and rt_decay
48        - added support for off_mode=normal
49        - added support for random, seq_position, seq_length and volume
50        - added v1 LFO opcodes to parser (no support in engine yet)
51        - added support for amp_veltrack and amp_velcurve_N
52        - fine-tuned the default velocity curve
53        - added support for transpose
54        - fixed crash when using sw_down/up
55        - improved logic for sw_lokey/hikey/up/down/last
56        - added more v1 aliases to parser
57        - reduced memory usage for sfz data
58        - RT-safeness: avoid malloc in audio thread
59        - fixed a bug that could cause voice stealing to fail
60        - optimized sample lookup
61        - improved support for exclusive groups (group, off_by and
62          off_mode)
63        - added support for controller triggered regions (on_locc/on_hicc)
64        - added support for loop_mode=one_shot
65        - fixed playback of 16 bit wav files on big endian CPUs
66        - added support for Ogg Vorbis sample files
67    
68      * SoundFont format engine:
69        - Initial implementation (not usable yet)
70        - RT-safeness: avoid malloc in audio thread
71        - fixed a bug that could cause voice stealing to fail
72    
73      * Host plugins:
74        - AU bugfix: failed to destroy its audio/MIDI devices
75        - Listen to all interfaces on Mac OS X (INADDR_ANY)
76        - VST bugfix: If the host called resume() before and after
77          changing sample rate or block size, the number of channels was
78          incorrectly set to two. This caused silence in Cubase 5.
79    
80      * MIDI driver:
81        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
82          the ALSA sequencer client name
83

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