47        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50          note (in this implementation of the sampler its simply hard routed to
51          the 1st effect send of the sampler channel, no matter what the actual
52          effect type is)
53        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54          note (in this implementation of the sampler its simply hard routed to
55          the 2nd effect send of the sampler channel, no matter what the actual
56          effect type is)
57        - implemented support for internal LADSPA effects
58        - raised limit of program change queue from 100 to 512

66          instrument on an engine channel (a.k.a. part). Some GigaStudio
67          instruments for example are splitted over several files like
68          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69        - Added new C++ API method Sampler::GetGlobalMaxVoices().
70        - Added new C++ API method Sampler::GetGlobalMaxStreams().

78          used it everywhere appropriate

81          SysEx way).
82        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83          and broken for ppc64. (Seq_cst loads and stores are actually not
84          used in LS, so the bug wasn't noticable.)
85        - lsatomic.h: added ARMv7 support
86

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

97        - handle special case when pan parameter in gig file has max or
98          min value
99        - Exclusive Groups: don't ever stop voices of the same note,

376    * Bug fixes:    * Bug fixes:
377      - Fixed crash which may occur when MIDI key + transpose is out of range      - Fixed crash which may occur when MIDI key + transpose is out of range
378        - minor valgrind fixes
379        - fixed crash which occurred when changing an already deployed sampler
380          channel to a different engine type
381        - fixed crash when deleting a sampler channel or changing engine
382          type while an instrument load was in progress
383        - bugfix: playing a note while changing the instrument could cause
384          a crash, or give "Handing back unknown region" error messages
385        - bugfix: calling SET VOICES (which Fantasia does on start and
386          refresh) could cause instruments to be unloaded
387        - Mac OS X: fixed name collision of enum in EffectControl and
388          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
389        - Mac OS X: fixed hanging threads
390        - Windows: disabled the previous thread fix on non-Mac systems, as
391          it caused hanging threads on Windows
392        - Fixed possible crashes due to corrupted MIDI/audio device list
393          after MIDI/audio device creation failure
394        - When creating MIDI instrument map entries with "PERSISTENT" type, the
395          instruments were uselessly precached with zero samples, however it still
396          took the full preloading time and on 1st program change the respective
397          instrument was completely reloaded again.
398        - fixed handling of rapid bank select and program change messages
399          sent to the same sampler channel (patch from the Open Octave
400          project, slightly adjusted)
401        - fixed crash when trying to create an effect instance with controls
402          which min and/or max values depend on the sample rate
403        - fixed bug #162
404        - bugfix: LADSPA_PATH was not evaluated correctly when containing
405          multiple paths (#165)
406        - thread safety fixes for the instrument loading thread
407        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
408          (#176)
409        - more thread safety fixes for the instrument loading thread
410        - sfz/sf2 engine: fixed crash when using small audio fragment size
411        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
412        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
413          introduced in previous fix)
414        - fixed crash when a channel received a program change while
415          playing a note in a key group
416        - fixed erroneous error message piping in VoiceBase.h
417          (labelled "Disk stream not available in time")
418        - Update effects on sample rate & period size changes (to avoid
419          crashes and noise on such transitions).
