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        - Mac OS X: Makefile fix for the install-strip target
21    
22      * general changes:
23        - Refactoring: moved the independent code from
24          the Gigasampler format engine to base classes
25        - command line option '--profile' is currently disabled, since the
26          respective profiling code is currently broken
27        - Introduced support for optional environment variable
28          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29          where the sampler shall look for instrument editor plugins
30          (patch by Luis Garrido, slightly modified).

32        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34          note (in this implementation of the sampler its simply hard routed to
35          the 1st effect send of the sampler channel, no matter what the actual
36          effect type is)
37        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 2nd effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented support for internal LADSPA effects
42        - raised limit of program change queue from 100 to 512
43          (as suggested by Alex Stone)

49          dimension zones is not a power of two
50        - made round robin use a counter for each region instead of each
51          key
52    
53      * SFZ format engine:
54        - Initial implementation (not usable yet)
55        - added support for v2 multiple stage envelope generators
56        - added a fine-tuned v1 envelope generator instead of using the

81          off_mode)
82        - added support for controller triggered regions (on_locc/on_hicc)
83        - added support for loop_mode=one_shot
84        - fixed playback of 16 bit wav files on big endian CPUs

158        - bugfix: pitch LFO controller "internal+aftertouch" was broken
159        - bugfix: filter keyboard tracking was broken
160        - filter performance fix (an unnecessary copy was made of the

164        - AU bugfix: failed to destroy its audio/MIDI devices
165        - Listen to all interfaces on Mac OS X (INADDR_ANY)
166        - VST bugfix: If the host called resume() before and after
167          changing sample rate or block size, the number of channels was

169        - save engine type (gig, sfz or sf2) in plugin state
170        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

224      * Bug fixes:
225        - Fixed crash which may occur when MIDI key + transpose is out of range
226        - minor valgrind fixes
227        - fixed crash which occurred when changing an already deployed sampler
228          channel to a different engine type
229        - fixed crash when deleting a sampler channel or changing engine
230          type while an instrument load was in progress
231        - bugfix: playing a note while changing the instrument could cause
232          a crash, or give "Handing back unknown region" error messages
233        - bugfix: calling SET VOICES (which Fantasia does on start and
234          refresh) could cause instruments to be unloaded
235        - Mac OS X: fixed name collision of enum in EffectControl and
236          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
237        - Mac OS X: fixed hanging threads
238        - Windows: disabled the previous thread fix on non-Mac systems, as
239          it caused hanging threads on Windows
240        - Fixed possible crashes due to corrupted MIDI/audio device list
241          after MIDI/audio device creation failure
242    
243    Version 1.0.0 (31 July 2009)
244    
245      * packaging changes:
246        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
247          causing e.g. the libgig test to fail when
248          "./configure --disable-jack-driver" was used
249          (patch by Alexis Ballier)
250        - fixed compilation with gcc 4.3
251        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
252        - fixed configure so it detects x86_64 (#107)
253        - fixes for building with newer MinGW versions
254        - fix for building with bison 2.4 (#111)
255        - fixed building with libgig installed in a non-standard directory
256        - minor fix in configure for mmsystem.h detection on MinGW
257        - Windows: look for editor plugins and Fantasia using base
258          directory of liblinuxsampler dll (look in the same directory and one
259          directory above)
260        - configure script fix: removed unconditional use of SSE
261        - fixed building with sqlite installed in a non-standard directory
262        - when cross-compiling, don't try to create instruments.db
263        - fix for new mingw-w64 version, which has usleep
264    
265      * general changes:
266        - bugfix: on some POSIX systems instrument editor plugins refused to
267          load as we used a non-portable Linux specific struct field
268          (fixes bug #70, patch by Ronald Baljeu)
269        - fixed endless loop which occured when loading an instrument editor
270          plugin DLL on Windows systems failed
271        - fixed memory leaks that occurred when liblinuxsampler was unloaded
272        - optimized the SynchronizedConfig class so it doesn't wait
273          unnecessarily long after an update
274        - added support for notifying instrument editors on note-on / note-off
275          events (e.g. to highlight the pressed keys on the virtual keyboard
276          of gigedit)
277        - added support for triggering notes by instrument editors (see above)
278        - be verbose on DLL load errors (on Linux)
279        - fixed di-harmonic triangle LFO implementation (this LFO implementation
280          is only used by very few systems, most pick the int math
281          implementation, which is usually faster)
282        - fixes for audio drivers with varying buffer sizes
283        - experimental support for running LinuxSampler as a DSSI, LV2 and
284          VST plugin
285        - notification events for stream/voice count statistics are now sent
286          only when there are actual changes
287        - added memory ordering constraints to improve stability on
288          multi-core and multi-cpu systems
289        - maximum voices and disk streams can now be altered at runtime
290        - fixed CPU feature detection on x86_64 (maybe fixes #108)
291        - automatic stacktrace mechanism is now turned off by default and can
292          be switched on by command line option "--stacktrace" (the automatic
293          stacktrace mechanism seems to be broken on most systems at the moment)
294        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
295          a pointer to the launched InstrumentEditor object
296        - added optional 3rd party user data parameter for following
297          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
298          InstrumentEditor::Launch(),
299          InstrumentManager::LaunchInstrumentEditor()
300        - theoretical fix: made SynchronizedConfig follow C++0x memory
301          model more strictly
302        - fixes for using large audio device buffers
303        - Windows: add the installation directory to the DLL search path
304          when loading an editor plugin (solves problems with VST and
305          gigedit on systems with other GTK versions installed)
306    
307      * audio driver:
308        - removed the nonsense audio channel constraint (which was hard coded to
309          max. 100 audio channels) for most audio drivers
310        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
311          opposed to the LSCP specs
312        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
313          reflected the wrong value
314        - fixed a memory management bug in ASIO driver
315        - Makefile fix: JACK_CFLAGS wasn't used
316        - JACK: use jack_client_open instead of the deprecated
317          jack_client_new
318        - added (experimental) CoreAudio driver
319        - applied old fixes to the ASIO driver that were included in the
320          previous binary release but accidentally never committed to CVS
321          (fixes #117)
322        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
323          win64)
324        - VST: added support for sample rate and buffer size changes
325        - VST: close editor (Fantasia) when the VST is removed
326        - VST: avoid opening Fantasia more than once for each VST instance
327        - VST: export main function as "main" on Linux too (fix for
328          energyXT)
329        - VST: changed number of output channels from one stereo to 16
330          stereo
331        - added channel routing, fxsends and midi maps to the settings
332          stored in the plugin state
333        - performance optimization of AudioChannel::MixTo() and
334          AudioChannel::CopyTo() methods using GCC vector exensions
335          (if available)
336        - ASIO fixes: avoid initializing the device twice, avoid throwing
337          exception when getting parameters from a disconnected device
338    
339      * MIDI driver:
340        - added JACK MIDI driver
341        - dispatch bank select as ordinary CC as well, the user might seriously
342          want to (mis)use it for some purpose ("fixed" in all current MIDI
343          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
344        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
345          CoreMidi or AU
346        - fixed mingw-w64 compilation error in MME driver
347        - made program change handling in MIDI thread real-time safe by
348          moving the logic to a non-RT thread
349        - fixed minor memory leak in ALSA driver
350    
351      * instruments database:
352        - avoid time consuming samples scanning when adding instruments
353          to the instruments database
354        - added support for handling lost files in the instruments database
355        - Implemented option for adding instruments in separate directories
356          in the instruments database
357          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
358        - work-around for missing fnmatch function on Windows to make
359          instrument database compilable
360        - added instrument database support on Windows
361          works with both standalone mode and VST plugin.
362          the instruments DB file is located in
363          %USERPROFILE%\.linuxsampler\instruments.db which allows different
364          databases for each windows user
365          if no DB is present it automatically creates the .linuxsampler subdir
366          and then creates an empty DB
367        - fixed recursive import, which was broken on Windows
368    
369      * Gigasampler format engine:
370        - fixed a memory leak that could happen when a channel was deleted
371          while notes were playing
372        - made it possible to load an instrument even if the audio thread
373          isn't running
374        - added partial support for the "Controller Triggered" MIDI rule,
375          enough for piano gigs with pedal noise samples
376        - minor fix: only mark FX sends as being modified if really the
377          respective FX send MIDI controller was used
378        - added support for GM global device volume SysEx message
379          (can be selected at compile time to either apply globally to the
380          whole sampler [default] or only to the sampler channels that are
381          connected to the respective MIDI input port the SysEx message arrived
382          on)
383        - bugfix: notes triggered at position 0 in the audio buffer were
384          sometimes wrongly killed in the same buffer, causing no sound to
385          be played
386        - added support for chromatic / drumkit mode Roland GS Sysex message
387          which is usally used to switch a part between chromatic sounds and
388          drumkit sounds (as opposed to their common default setting of MIDI
389          part 10 being a drumkit part and all other ones chromatic parts), in
390          LS however one can switch between the first 16 MIDI instrument maps
391          defined for the sampler
392        - made it possible to create multiple sample channels even if the
393          audio thread isn't running
394        - fixed crash when removing channel with active voices (#116)
395        - bugfix: on sample reference changes (instrument editor), only
396          un-cache the respective sample if it's really not used by any
397          sampler engine anymore
398        - re-cache samples in case they were changed by an instrument editor,
399          e.g. when a sample was added while playing (#82)
400        - fixed hanging notes which occured when note-off event had the exact
401          same time stamp as the voice's note-on event and occured both in the
402          same audio fragment cycle (fixes bug #112)
403        - added support for the "fine tune" and "pitch bend range"
404          instrument-level gig parameters
405        - fixed minor artifacts in pitch bend handling
406        - added support for GS Reset SysEx message
407        - allow gig files to use unlimited downward pitch shifting
408        - added a limit check for upward pitch shifting
409        - bugfix: sometimes, when playing a note twice fast, the second
410          note was silent
411        - fixed crash happening when a pitch bend event arrived at the
412          same time a new instrument was loading
413    
414      * LSCP server:
415        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
416          react on MIDI data arriving on certain sampler channels (so far only
417          Note-On and Note-Off events are sent via this LSCP event)
418        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
419          react on MIDI data arriving on certain MIDI input devices (so far only
420          Note-On and Note-Off events are sent via this LSCP event)
421        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
422          SET DB_INSTRUMENT FILE_PATH
423        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
424          frontends to send MIDI messages to specific sampler channel
425        - added two additional fields to GET FILE INSTRUMENT INFO command -
426          KEY_BINDINGS and KEYSWITCH_BINDINGS
427        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
428          was incorrect
429        - Optimized the retrieval of the MIDI instrument mappings
430        - added new LSCP command "SET VOICES" to globally alter the maximum
431          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
432          be triggered respectively
433        - added new LSCP command "SET STREAMS" to globally alter the maximum
434          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
435          which will be triggered respectively
436        - bugfix: retry if "select" returns EINTR (this fixes a crash when
437          a gigedit file dialog is opened)
438        - close all connections when LSCPServer is deleted
439        - hard close of all sockets on exit
440        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
441          driver
442    
443      * Bug fixes:
444        - fixed a crash which occurs when removing a sampler channel waiting
445          to start instrument loading after another channel
446        - fixed a crash which occurs when removing a sampler channel with
447          instrument loading in progress (bug #113)
448        - fixed termination caused by uncaught exception when adding MIDI
449          instrument with PERSISTENT load mode
450        - fixed possible iterator invalidations when resetting the sampler
451        - fixed memory leaks when issuing the following LSCP commands:
452          GET AUDIO_OUTPUT_DRIVER INFO
453          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
454          GET MIDI_INPUT_DRIVER INFO
455          GET MIDI_INPUT_DRIVER_PARAMETER INFO
456        - fixed possible compilation error when sqlite is not present
457        - fixed orphaned pointers when setting maximum voices limit (bug #118)
458        - fixed crash when changing the audio output device of a sampler
459          channel with loaded instrument and start playing notes
460        - fixed endless loop in Engine::SuspendAll() (bug #120)
461        - fixed a low-level atomic load function that was broken on 64-bit
462          PowerPC, which probably could cause crashes on that platform
463        - fixed a memory management error which could cause a crash when a
464          plugin was unloaded
465        - bugfix: two private structs had the same name, which could cause
466          problems if the linker chose the wrong constructor
467        - fixed low-level ConditionServer usage bug that caused lockups on
468          Windows
469    
470    
471    Version 0.5.1 (6 December 2007)
472    
473      * packaging changes:
474        - added autoconf checks for pthread library
475        - added autoconf check for pthread bug found on certain NPTL-enabled
476          glibc versions (see Gentoo bug report #194076)
477        - added autoconf checks for MS Windows
478    
479      * general changes:
480        - bugfix: the thread used by an editor plugin didn't die when the
481          editor closed
482        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
483          out all the space. operator--() did not apply size_mask after
484          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
485          order to avoid problems with the _NonVolatileReader functions.
486        - bugfix: Stream.h: added a missing divide by BytesPerSample in
487          GetWriteSpace(). Since this function is currently only used in
488          the stream's qsort() compare function, it didn't trigger any
489          bugs.
490        - Resampler.h, Synthesizer.h: cubic interpolation now works in
491          24bit mode too. Faster method to read 24bit words on little
492          endian machines (x86): replaced 3 byte reads + shifts with a 1
493          unaligned 32bit read and shift
494        - experimental support for MS Windows (MIDI input via MME, AUDIO
495          output via ASIO)
496        - made handling of SIGINT signal (Ctrl-C) a bit more robust
497        - support for monitoring the total number of active disk streams
498          (new LSCP commands: GET TOTAL_STREAM_COUNT,
499          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
500    
501      * AUDIO driver:
502        - added Windows ASIO low latency audio driver
503    
504      * MIDI driver:
505        - added MME Windows MIDI driver
506    
507      * LSCP server:
508        - added support for Windows style path / filenames, however with
509          forward slash path separators instead of backslash
510          (i.e. "C:/foo/bar.gig")
511        - allow naughty liblscp to send non-string device parameters within
512          apostrophes as well
513        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
514          "LIST FILE INSTRUMENTS <file>" and
515          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
516          about an arbitrary instrument file on the system where the sampler is
517          running on
