1  Version CVS HEAD (?)  Version CVS HEAD (?)
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

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)
57        - added support for v2 multiple stage envelope generators

342        - fixed memory leaks that occurred when liblinuxsampler was unloaded
343        - optimized the SynchronizedConfig class so it doesn't wait
344          unnecessarily long after an update
345        - added support for notifying instrument editors on note-on / note-off
346          events (e.g. to highlight the pressed keys on the virtual keyboard
347          of gigedit)
348        - added support for triggering notes by instrument editors (see above)
349        - be verbose on DLL load errors (on Linux)
350        - fixed di-harmonic triangle LFO implementation (this LFO implementation
351          is only used by very few systems, most pick the int math
352          implementation, which is usually faster)
353        - fixes for audio drivers with varying buffer sizes
354        - experimental support for running LinuxSampler as a DSSI, LV2 and
355          VST plugin
356        - notification events for stream/voice count statistics are now sent
357          only when there are actual changes
358        - added memory ordering constraints to improve stability on
359          multi-core and multi-cpu systems
360        - maximum voices and disk streams can now be altered at runtime
361        - fixed CPU feature detection on x86_64 (maybe fixes #108)
362        - automatic stacktrace mechanism is now turned off by default and can
363          be switched on by command line option "--stacktrace" (the automatic
364          stacktrace mechanism seems to be broken on most systems at the moment)
365        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
366          a pointer to the launched InstrumentEditor object
367        - added optional 3rd party user data parameter for following
368          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
369          InstrumentEditor::Launch(),
370          InstrumentManager::LaunchInstrumentEditor()
371        - theoretical fix: made SynchronizedConfig follow C++0x memory
372          model more strictly
373        - fixes for using large audio device buffers
374        - Windows: add the installation directory to the DLL search path
375          when loading an editor plugin (solves problems with VST and
376          gigedit on systems with other GTK versions installed)

385        - fixed a memory management bug in ASIO driver
386        - Makefile fix: JACK_CFLAGS wasn't used
387        - JACK: use jack_client_open instead of the deprecated
388          jack_client_new
389        - added (experimental) CoreAudio driver
390        - applied old fixes to the ASIO driver that were included in the
391          previous binary release but accidentally never committed to CVS
392          (fixes #117)
393        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
394          win64)
395        - VST: added support for sample rate and buffer size changes
396        - VST: close editor (Fantasia) when the VST is removed
397        - VST: avoid opening Fantasia more than once for each VST instance
398        - VST: export main function as "main" on Linux too (fix for
399          energyXT)
400        - VST: changed number of output channels from one stereo to 16
401          stereo
402        - added channel routing, fxsends and midi maps to the settings
403          stored in the plugin state
404        - performance optimization of AudioChannel::MixTo() and
405          AudioChannel::CopyTo() methods using GCC vector exensions
406          (if available)
407        - ASIO fixes: avoid initializing the device twice, avoid throwing
408          exception when getting parameters from a disconnected device
409    
410      * MIDI driver:
411        - added JACK MIDI driver
412        - dispatch bank select as ordinary CC as well, the user might seriously
413          want to (mis)use it for some purpose ("fixed" in all current MIDI
414          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
415        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
416          CoreMidi or AU
417        - fixed mingw-w64 compilation error in MME driver
418        - made program change handling in MIDI thread real-time safe by
419          moving the logic to a non-RT thread
420        - fixed minor memory leak in ALSA driver
421    
422    * instruments database:    * instruments database:
423      - avoid time consuming samples scanning when adding instruments      - avoid time consuming samples scanning when adding instruments
424        to the instruments database        to the instruments database
425        - added support for handling lost files in the instruments database
426        - Implemented option for adding instruments in separate directories
427          in the instruments database
428          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
429        - work-around for missing fnmatch function on Windows to make
430          instrument database compilable
431        - added instrument database support on Windows
432          works with both standalone mode and VST plugin.
433          the instruments DB file is located in
434          %USERPROFILE%\.linuxsampler\instruments.db which allows different
435          databases for each windows user
436          if no DB is present it automatically creates the .linuxsampler subdir
437          and then creates an empty DB
438        - fixed recursive import, which was broken on Windows
439    
440      * Gigasampler format engine:
441        - fixed a memory leak that could happen when a channel was deleted
442          while notes were playing
443        - made it possible to load an instrument even if the audio thread
444          isn't running
445        - added partial support for the "Controller Triggered" MIDI rule,
446          enough for piano gigs with pedal noise samples
447        - minor fix: only mark FX sends as being modified if really the
448          respective FX send MIDI controller was used
449        - added support for GM global device volume SysEx message
450          (can be selected at compile time to either apply globally to the
451          whole sampler [default] or only to the sampler channels that are
452          connected to the respective MIDI input port the SysEx message arrived
453          on)
454        - bugfix: notes triggered at position 0 in the audio buffer were
455          sometimes wrongly killed in the same buffer, causing no sound to
456          be played
457        - added support for chromatic / drumkit mode Roland GS Sysex message
458          which is usally used to switch a part between chromatic sounds and
459          drumkit sounds (as opposed to their common default setting of MIDI
460          part 10 being a drumkit part and all other ones chromatic parts), in
461          LS however one can switch between the first 16 MIDI instrument maps
462          defined for the sampler
463        - made it possible to create multiple sample channels even if the
464          audio thread isn't running
465        - fixed crash when removing channel with active voices (#116)
466        - bugfix: on sample reference changes (instrument editor), only
467          un-cache the respective sample if it's really not used by any
468          sampler engine anymore
469        - re-cache samples in case they were changed by an instrument editor,
470          e.g. when a sample was added while playing (#82)
471        - fixed hanging notes which occured when note-off event had the exact
472          same time stamp as the voice's note-on event and occured both in the
473          same audio fragment cycle (fixes bug #112)
474        - added support for the "fine tune" and "pitch bend range"
475          instrument-level gig parameters
476        - fixed minor artifacts in pitch bend handling
477        - added support for GS Reset SysEx message
478        - allow gig files to use unlimited downward pitch shifting
479        - added a limit check for upward pitch shifting
480        - bugfix: sometimes, when playing a note twice fast, the second
481          note was silent
482        - fixed crash happening when a pitch bend event arrived at the
483          same time a new instrument was loading
484    
485      * LSCP server:
486        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
487          react on MIDI data arriving on certain sampler channels (so far only
488          Note-On and Note-Off events are sent via this LSCP event)
489        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
490          react on MIDI data arriving on certain MIDI input devices (so far only
491          Note-On and Note-Off events are sent via this LSCP event)
492        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
493          SET DB_INSTRUMENT FILE_PATH
494        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
495          frontends to send MIDI messages to specific sampler channel
496        - added two additional fields to GET FILE INSTRUMENT INFO command -
497          KEY_BINDINGS and KEYSWITCH_BINDINGS
498        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
499          was incorrect
500        - Optimized the retrieval of the MIDI instrument mappings
501        - added new LSCP command "SET VOICES" to globally alter the maximum
502          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
503          be triggered respectively
504        - added new LSCP command "SET STREAMS" to globally alter the maximum
505          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
506          which will be triggered respectively
507        - bugfix: retry if "select" returns EINTR (this fixes a crash when
508          a gigedit file dialog is opened)
509        - close all connections when LSCPServer is deleted
510        - hard close of all sockets on exit
511        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
512          driver
513    
514      * Bug fixes:
515        - fixed a crash which occurs when removing a sampler channel waiting
516          to start instrument loading after another channel
517        - fixed a crash which occurs when removing a sampler channel with
518          instrument loading in progress (bug #113)
519        - fixed termination caused by uncaught exception when adding MIDI
520          instrument with PERSISTENT load mode
521        - fixed possible iterator invalidations when resetting the sampler
522        - fixed memory leaks when issuing the following LSCP commands:
523          GET AUDIO_OUTPUT_DRIVER INFO
524          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
525          GET MIDI_INPUT_DRIVER INFO
526          GET MIDI_INPUT_DRIVER_PARAMETER INFO
527        - fixed possible compilation error when sqlite is not present
528        - fixed orphaned pointers when setting maximum voices limit (bug #118)
529        - fixed crash when changing the audio output device of a sampler
530          channel with loaded instrument and start playing notes
531        - fixed endless loop in Engine::SuspendAll() (bug #120)
532        - fixed a low-level atomic load function that was broken on 64-bit
533          PowerPC, which probably could cause crashes on that platform
534        - fixed a memory management error which could cause a crash when a
535          plugin was unloaded
536        - bugfix: two private structs had the same name, which could cause
537          problems if the linker chose the wrong constructor
538        - fixed low-level ConditionServer usage bug that caused lockups on
539          Windows
