3    * packaging changes:    * 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        - use loop markers from sample file if loop_start and loop_end are
70          not set in sfz file
71    
72      * SoundFont format engine:
73        - Initial implementation (not usable yet)
74        - RT-safeness: avoid malloc in audio thread
75        - fixed a bug that could cause voice stealing to fail
76    
77      * Host plugins:
78        - AU bugfix: failed to destroy its audio/MIDI devices
79        - Listen to all interfaces on Mac OS X (INADDR_ANY)
80        - VST bugfix: If the host called resume() before and after
81          changing sample rate or block size, the number of channels was
82          incorrectly set to two. This caused silence in Cubase 5.
83        - save engine type (gig, sfz or sf2) in plugin state
84        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
85          64 bit Windows
86    
87      * MIDI driver:
88        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
89          the ALSA sequencer client name
90        - removed limit of maximum amount of MIDI ports per MIDI device, since
91          there is no reason for this limit
92    
93      * LSCP server:
94        - added support for sending MIDI CC messages via LSCP command
95          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

108        - added LSCP command "SET EFFECT_INSTANCE_INPUT_CONTROL VALUE
109          <effect-instance> <input-control> <value>"
110        - added LSCP command "GET SEND_EFFECT_CHAINS <audio-device>"

120          <effect-chain> <effect-chain-pos> <effect-instance>"
121        - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>
122          <effect-chain> <chain-pos>"
123        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
124          <fx_send_id> <effect_chain> <chain_pos>"
125        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
126    
127      * Bug fixes:
128        - Fixed crash which may occur when MIDI key + transpose is out of range
129        - minor valgrind fixes
130        - fixed crash which occured when changing an already deployed sampler
131          channel to a different engine type
132        - fixed crash when deleting a sampler channel or changing engine
133          type while an instrument load was in progress
134        - bugfix: playing a note while changing the instrument could cause
135          a crash, or give "Handing back unknown region" error messages
136        - bugfix: calling SET VOICES (which Fantasia does on start and
137          refresh) could cause instruments to be unloaded
138    
139    Version 1.0.0 (31 July 2009)
140    
141      * packaging changes:
142        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
143          causing e.g. the libgig test to fail when
144          "./configure --disable-jack-driver" was used
145          (patch by Alexis Ballier)
146        - fixed compilation with gcc 4.3
147        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
148        - fixed configure so it detects x86_64 (#107)
149        - fixes for building with newer MinGW versions
150        - fix for building with bison 2.4 (#111)
151        - fixed building with libgig installed in a non-standard directory
152        - minor fix in configure for mmsystem.h detection on MinGW
153        - Windows: look for editor plugins and Fantasia using base
154          directory of liblinuxsampler dll (look in the same directory and one
155          directory above)
156        - configure script fix: removed unconditional use of SSE
157        - fixed building with sqlite installed in a non-standard directory
158        - when cross-compiling, don't try to create instruments.db
159        - fix for new mingw-w64 version, which has usleep
160    
161      * general changes:
162        - bugfix: on some POSIX systems instrument editor plugins refused to
163          load as we used a non-portable Linux specific struct field
164          (fixes bug #70, patch by Ronald Baljeu)
165        - fixed endless loop which occured when loading an instrument editor
166          plugin DLL on Windows systems failed
167        - fixed memory leaks that occurred when liblinuxsampler was unloaded
168        - optimized the SynchronizedConfig class so it doesn't wait
169          unnecessarily long after an update
170        - added support for notifying instrument editors on note-on / note-off
171          events (e.g. to highlight the pressed keys on the virtual keyboard
172          of gigedit)
173        - added support for triggering notes by instrument editors (see above)
174        - be verbose on DLL load errors (on Linux)
175        - fixed di-harmonic triangle LFO implementation (this LFO implementation
176          is only used by very few systems, most pick the int math
177          implementation, which is usually faster)
178        - fixes for audio drivers with varying buffer sizes
179        - experimental support for running LinuxSampler as a DSSI, LV2 and
180          VST plugin
181        - notification events for stream/voice count statistics are now sent
182          only when there are actual changes
183        - added memory ordering constraints to improve stability on
184          multi-core and multi-cpu systems
185        - maximum voices and disk streams can now be altered at runtime
186        - fixed CPU feature detection on x86_64 (maybe fixes #108)
187        - automatic stacktrace mechanism is now turned off by default and can
188          be switched on by command line option "--stacktrace" (the automatic
189          stacktrace mechanism seems to be broken on most systems at the moment)
190        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
191          a pointer to the launched InstrumentEditor object
192        - added optional 3rd party user data parameter for following
193          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
194          InstrumentEditor::Launch(),
195          InstrumentManager::LaunchInstrumentEditor()
196        - theoretical fix: made SynchronizedConfig follow C++0x memory
197          model more strictly
198        - fixes for using large audio device buffers
199        - Windows: add the installation directory to the DLL search path
200          when loading an editor plugin (solves problems with VST and
201          gigedit on systems with other GTK versions installed)
202    
203      * audio driver:
204        - removed the nonsense audio channel constraint (which was hard coded to
205          max. 100 audio channels) for most audio drivers
206        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
207          opposed to the LSCP specs
208        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
209          reflected the wrong value
210        - fixed a memory management bug in ASIO driver
211        - Makefile fix: JACK_CFLAGS wasn't used
212        - JACK: use jack_client_open instead of the deprecated
213          jack_client_new
214        - added (experimental) CoreAudio driver
215        - applied old fixes to the ASIO driver that were included in the
216          previous binary release but accidentally never committed to CVS
217          (fixes #117)
218        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
219          win64)
220        - VST: added support for sample rate and buffer size changes
221        - VST: close editor (Fantasia) when the VST is removed
222        - VST: avoid opening Fantasia more than once for each VST instance
223        - VST: export main function as "main" on Linux too (fix for
224          energyXT)
225        - VST: changed number of output channels from one stereo to 16
226          stereo
227        - added channel routing, fxsends and midi maps to the settings
228          stored in the plugin state
229        - performance optimization of AudioChannel::MixTo() and
230          AudioChannel::CopyTo() methods using GCC vector exensions
231          (if available)
232        - ASIO fixes: avoid initializing the device twice, avoid throwing
233          exception when getting parameters from a disconnected device
234    
235      * MIDI driver:
236        - added JACK MIDI driver
237        - dispatch bank select as ordinary CC as well, the user might seriously
238          want to (mis)use it for some purpose ("fixed" in all current MIDI
239          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
240        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
241          CoreMidi or AU
242        - fixed mingw-w64 compilation error in MME driver
243        - made program change handling in MIDI thread real-time safe by
244          moving the logic to a non-RT thread
245        - fixed minor memory leak in ALSA driver
246    
247      * instruments database:
248        - avoid time consuming samples scanning when adding instruments
249          to the instruments database
250        - added support for handling lost files in the instruments database
251        - Implemented option for adding instruments in separate directories
252          in the instruments database
253          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
254        - work-around for missing fnmatch function on Windows to make
255          instrument database compilable
256        - added instrument database support on Windows
257          works with both standalone mode and VST plugin.
258          the instruments DB file is located in
259          %USERPROFILE%\.linuxsampler\instruments.db which allows different
260          databases for each windows user
261          if no DB is present it automatically creates the .linuxsampler subdir
262          and then creates an empty DB
263        - fixed recursive import, which was broken on Windows
264    
265      * Gigasampler format engine:
266        - fixed a memory leak that could happen when a channel was deleted
267          while notes were playing
268        - made it possible to load an instrument even if the audio thread
269          isn't running
270        - added partial support for the "Controller Triggered" MIDI rule,
271          enough for piano gigs with pedal noise samples
272        - minor fix: only mark FX sends as being modified if really the
273          respective FX send MIDI controller was used
274        - added support for GM global device volume SysEx message
275          (can be selected at compile time to either apply globally to the
276          whole sampler [default] or only to the sampler channels that are
277          connected to the respective MIDI input port the SysEx message arrived
278          on)
279        - bugfix: notes triggered at position 0 in the audio buffer were
280          sometimes wrongly killed in the same buffer, causing no sound to
281          be played
282        - added support for chromatic / drumkit mode Roland GS Sysex message
283          which is usally used to switch a part between chromatic sounds and
284          drumkit sounds (as opposed to their common default setting of MIDI
285          part 10 being a drumkit part and all other ones chromatic parts), in
286          LS however one can switch between the first 16 MIDI instrument maps
287          defined for the sampler
288        - made it possible to create multiple sample channels even if the
289          audio thread isn't running
290        - fixed crash when removing channel with active voices (#116)
291        - bugfix: on sample reference changes (instrument editor), only
292          un-cache the respective sample if it's really not used by any
293          sampler engine anymore
294        - re-cache samples in case they were changed by an instrument editor,
295          e.g. when a sample was added while playing (#82)
296        - fixed hanging notes which occured when note-off event had the exact
297          same time stamp as the voice's note-on event and occured both in the
298          same audio fragment cycle (fixes bug #112)
299        - added support for the "fine tune" and "pitch bend range"
300          instrument-level gig parameters
301        - fixed minor artifacts in pitch bend handling
302        - added support for GS Reset SysEx message
303        - allow gig files to use unlimited downward pitch shifting
304        - added a limit check for upward pitch shifting
305        - bugfix: sometimes, when playing a note twice fast, the second
306          note was silent
307        - fixed crash happening when a pitch bend event arrived at the
308          same time a new instrument was loading
309    
310      * LSCP server:
311        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
312          react on MIDI data arriving on certain sampler channels (so far only
313          Note-On and Note-Off events are sent via this LSCP event)
314        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
315          react on MIDI data arriving on certain MIDI input devices (so far only
316          Note-On and Note-Off events are sent via this LSCP event)
317        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
318          SET DB_INSTRUMENT FILE_PATH
319        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
320          frontends to send MIDI messages to specific sampler channel
321        - added two additional fields to GET FILE INSTRUMENT INFO command -
322          KEY_BINDINGS and KEYSWITCH_BINDINGS
323        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
324          was incorrect
325        - Optimized the retrieval of the MIDI instrument mappings
326        - added new LSCP command "SET VOICES" to globally alter the maximum
327          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
328          be triggered respectively
329        - added new LSCP command "SET STREAMS" to globally alter the maximum
330          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
331          which will be triggered respectively
332        - bugfix: retry if "select" returns EINTR (this fixes a crash when
333          a gigedit file dialog is opened)
334        - close all connections when LSCPServer is deleted
335        - hard close of all sockets on exit
336        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
337          driver
338    
339      * Bug fixes:
340        - fixed a crash which occurs when removing a sampler channel waiting
341          to start instrument loading after another channel
342        - fixed a crash which occurs when removing a sampler channel with
343          instrument loading in progress (bug #113)
344        - fixed termination caused by uncaught exception when adding MIDI
345          instrument with PERSISTENT load mode
346        - fixed possible iterator invalidations when resetting the sampler
347        - fixed memory leaks when issuing the following LSCP commands:
348          GET AUDIO_OUTPUT_DRIVER INFO
349          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
350          GET MIDI_INPUT_DRIVER INFO
351          GET MIDI_INPUT_DRIVER_PARAMETER INFO
352        - fixed possible compilation error when sqlite is not present
353        - fixed orphaned pointers when setting maximum voices limit (bug #118)
354        - fixed crash when changing the audio output device of a sampler
355          channel with loaded instrument and start playing notes
356        - fixed endless loop in Engine::SuspendAll() (bug #120)
357        - fixed a low-level atomic load function that was broken on 64-bit
358          PowerPC, which probably could cause crashes on that platform
359        - fixed a memory management error which could cause a crash when a
360          plugin was unloaded
361        - bugfix: two private structs had the same name, which could cause
362          problems if the linker chose the wrong constructor
363        - fixed low-level ConditionServer usage bug that caused lockups on
364          Windows
365    
366    
367    Version 0.5.1 (6 December 2007)
368    
369      * packaging changes:
370      - added autoconf checks for pthread library      - added autoconf checks for pthread library
371      - added autoconf check for pthread bug found on certain NPTL-enabled      - added autoconf check for pthread bug found on certain NPTL-enabled
372        glibc versions (see Gentoo bug report #194076)        glibc versions (see Gentoo bug report #194076)
373        - added autoconf checks for MS Windows
374    
375    * general changes:    * general changes:
376      - bugfix: the thread used by an editor plugin didn't die when the      - bugfix: the thread used by an editor plugin didn't die when the
377        editor closed        editor closed
378        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
379          out all the space. operator--() did not apply size_mask after
380          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
381          order to avoid problems with the _NonVolatileReader functions.
382        - bugfix: Stream.h: added a missing divide by BytesPerSample in
383          GetWriteSpace(). Since this function is currently only used in
384          the stream's qsort() compare function, it didn't trigger any
385          bugs.
386        - Resampler.h, Synthesizer.h: cubic interpolation now works in
387          24bit mode too. Faster method to read 24bit words on little
388          endian machines (x86): replaced 3 byte reads + shifts with a 1
389          unaligned 32bit read and shift
