2    
3      * plugin changes:
4        - LV2 "state" extension 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

51          dimension zones is not a power of two
52        - made round robin use a counter for each region instead of each
53          key
54    
55      * SFZ format engine:
56        - Initial implementation (not usable yet)

299          took the full preloading time and on 1st program change the respective
300          instrument was completely reloaded again.
301        - fixed handling of rapid bank select and program change messages
302          sent to the same sampler channel (patch from the Open Octave

340        unnecessarily long after an update        unnecessarily long after an update
341        - added support for notifying instrument editors on note-on / note-off
342          events (e.g. to highlight the pressed keys on the virtual keyboard
343          of gigedit)
344        - added support for triggering notes by instrument editors (see above)
345        - be verbose on DLL load errors (on Linux)
346        - fixed di-harmonic triangle LFO implementation (this LFO implementation
347          is only used by very few systems, most pick the int math
348          implementation, which is usually faster)
349        - fixes for audio drivers with varying buffer sizes
350        - experimental support for running LinuxSampler as a DSSI, LV2 and
351          VST plugin
352        - notification events for stream/voice count statistics are now sent
353          only when there are actual changes
354        - added memory ordering constraints to improve stability on
355          multi-core and multi-cpu systems
356        - maximum voices and disk streams can now be altered at runtime
357        - fixed CPU feature detection on x86_64 (maybe fixes #108)
358        - automatic stacktrace mechanism is now turned off by default and can
359          be switched on by command line option "--stacktrace" (the automatic
360          stacktrace mechanism seems to be broken on most systems at the moment)
361        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
362          a pointer to the launched InstrumentEditor object
363        - added optional 3rd party user data parameter for following
364          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
365          InstrumentEditor::Launch(),
366          InstrumentManager::LaunchInstrumentEditor()
367        - theoretical fix: made SynchronizedConfig follow C++0x memory
368          model more strictly
369        - fixes for using large audio device buffers
370        - Windows: add the installation directory to the DLL search path
371          when loading an editor plugin (solves problems with VST and
372          gigedit on systems with other GTK versions installed)

382        - Makefile fix: JACK_CFLAGS wasn't used
383        - JACK: use jack_client_open instead of the deprecated
384          jack_client_new
385        - added (experimental) CoreAudio driver
386        - applied old fixes to the ASIO driver that were included in the
387          previous binary release but accidentally never committed to CVS
388          (fixes #117)
389        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
390          win64)
391        - VST: added support for sample rate and buffer size changes
392        - VST: close editor (Fantasia) when the VST is removed
393        - VST: avoid opening Fantasia more than once for each VST instance
394        - VST: export main function as "main" on Linux too (fix for
395          energyXT)
396        - VST: changed number of output channels from one stereo to 16
397          stereo
398        - added channel routing, fxsends and midi maps to the settings
399          stored in the plugin state
400        - performance optimization of AudioChannel::MixTo() and
401          AudioChannel::CopyTo() methods using GCC vector exensions
402          (if available)
403        - ASIO fixes: avoid initializing the device twice, avoid throwing
404          exception when getting parameters from a disconnected device
405    
406      * MIDI driver:
407        - added JACK MIDI driver
408        - dispatch bank select as ordinary CC as well, the user might seriously
409          want to (mis)use it for some purpose ("fixed" in all current MIDI
410          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
411        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
412          CoreMidi or AU
413        - fixed mingw-w64 compilation error in MME driver
414        - made program change handling in MIDI thread real-time safe by
415          moving the logic to a non-RT thread
416        - fixed minor memory leak in ALSA driver
417

419      - avoid time consuming samples scanning when adding instruments      - avoid time consuming samples scanning when adding instruments
420        to the instruments database        to the instruments database
421        - added support for handling lost files in the instruments database
422        - Implemented option for adding instruments in separate directories
423          in the instruments database
424          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
425        - work-around for missing fnmatch function on Windows to make
426          instrument database compilable
427        - added instrument database support on Windows
428          works with both standalone mode and VST plugin.
429          the instruments DB file is located in
430          %USERPROFILE%\.linuxsampler\instruments.db which allows different
431          databases for each windows user
432          if no DB is present it automatically creates the .linuxsampler subdir
433          and then creates an empty DB
434        - fixed recursive import, which was broken on Windows
435    
436    * Gigasampler format engine:    * Gigasampler format engine:

440        isn't running        isn't running
441        - added partial support for the "Controller Triggered" MIDI rule,
442          enough for piano gigs with pedal noise samples
443        - minor fix: only mark FX sends as being modified if really the
444          respective FX send MIDI controller was used
445        - added support for GM global device volume SysEx message
446          (can be selected at compile time to either apply globally to the
447          whole sampler [default] or only to the sampler channels that are
448          connected to the respective MIDI input port the SysEx message arrived
449          on)
450        - bugfix: notes triggered at position 0 in the audio buffer were
451          sometimes wrongly killed in the same buffer, causing no sound to
452          be played
453        - added support for chromatic / drumkit mode Roland GS Sysex message
454          which is usally used to switch a part between chromatic sounds and
455          drumkit sounds (as opposed to their common default setting of MIDI
456          part 10 being a drumkit part and all other ones chromatic parts), in
457          LS however one can switch between the first 16 MIDI instrument maps
458          defined for the sampler
459        - made it possible to create multiple sample channels even if the
460          audio thread isn't running
461        - fixed crash when removing channel with active voices (#116)
462        - bugfix: on sample reference changes (instrument editor), only
463          un-cache the respective sample if it's really not used by any
464          sampler engine anymore
465        - re-cache samples in case they were changed by an instrument editor,
466          e.g. when a sample was added while playing (#82)
467        - fixed hanging notes which occured when note-off event had the exact
468          same time stamp as the voice's note-on event and occured both in the
469          same audio fragment cycle (fixes bug #112)
470        - added support for the "fine tune" and "pitch bend range"
471          instrument-level gig parameters
472        - fixed minor artifacts in pitch bend handling
473        - added support for GS Reset SysEx message
474        - allow gig files to use unlimited downward pitch shifting
475        - added a limit check for upward pitch shifting
476        - bugfix: sometimes, when playing a note twice fast, the second
477          note was silent
478        - fixed crash happening when a pitch bend event arrived at the
479          same time a new instrument was loading
480    
481      * LSCP server:
482        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
483          react on MIDI data arriving on certain sampler channels (so far only
484          Note-On and Note-Off events are sent via this LSCP event)
485        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
486          react on MIDI data arriving on certain MIDI input devices (so far only
487          Note-On and Note-Off events are sent via this LSCP event)
488        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
489          SET DB_INSTRUMENT FILE_PATH
490        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
491          frontends to send MIDI messages to specific sampler channel
492        - added two additional fields to GET FILE INSTRUMENT INFO command -
493          KEY_BINDINGS and KEYSWITCH_BINDINGS
494        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
495          was incorrect
496        - Optimized the retrieval of the MIDI instrument mappings
497        - added new LSCP command "SET VOICES" to globally alter the maximum
498          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
499          be triggered respectively
500        - added new LSCP command "SET STREAMS" to globally alter the maximum
501          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
502          which will be triggered respectively
503        - bugfix: retry if "select" returns EINTR (this fixes a crash when
504          a gigedit file dialog is opened)
505        - close all connections when LSCPServer is deleted
506        - hard close of all sockets on exit
507        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
508          driver
509    
510      * Bug fixes:
511        - fixed a crash which occurs when removing a sampler channel waiting
512          to start instrument loading after another channel
513        - fixed a crash which occurs when removing a sampler channel with
514          instrument loading in progress (bug #113)
515        - fixed termination caused by uncaught exception when adding MIDI
516          instrument with PERSISTENT load mode
517        - fixed possible iterator invalidations when resetting the sampler
518        - fixed memory leaks when issuing the following LSCP commands:
519          GET AUDIO_OUTPUT_DRIVER INFO
520          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
521          GET MIDI_INPUT_DRIVER INFO
522          GET MIDI_INPUT_DRIVER_PARAMETER INFO
523        - fixed possible compilation error when sqlite is not present
524        - fixed orphaned pointers when setting maximum voices limit (bug #118)
525        - fixed crash when changing the audio output device of a sampler
526          channel with loaded instrument and start playing notes
527        - fixed endless loop in Engine::SuspendAll() (bug #120)
528        - fixed a low-level atomic load function that was broken on 64-bit
529          PowerPC, which probably could cause crashes on that platform
530        - fixed a memory management error which could cause a crash when a
531          plugin was unloaded
532        - bugfix: two private structs had the same name, which could cause
533          problems if the linker chose the wrong constructor
534        - fixed low-level ConditionServer usage bug that caused lockups on
535          Windows
