46        (patch by Luis Garrido, slightly modified).        (patch by Luis Garrido, slightly modified).
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
59          (as suggested by Alex Stone)

61        - experimental support for per voice equalization
62        - added command line option --exec-after-init
63        - Introduced new C++ API method:
64          EngineChannel::InstrumentFileName(int index)
65          allowing to retrieve the whole list of files used for the loaded
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().
71        - Added new C++ API method Sampler::SetGlobalMaxVoices().

78          used it everywhere appropriate
79        - Immediately apply scale tuning changes to active voices.
80        - Exposed scale tuning to C++ API (along to the already existing standard
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        - Added support for multiple MIDI input ports per sampler channel (and
87          added various new C++ methods for this new feature / design change, old
88          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89          as deprecated but are still there and should provide full behavior
90          backward compatibility).
91        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92          unsafe and caused compilation error with clang 2.x).
93    
94    * Gigasampler format engine:    * Gigasampler format engine:
95      - implemented the "round robin keyboard" dimension      - implemented the "round robin keyboard" dimension

102        - filter performance fix (an unnecessary copy was made of the
103          filter parameters in each sub fragment)
104        - handle special case when pan parameter in gig file has max or
105          min value
106        - Exclusive Groups: don't ever stop voices of the same note,
107          doesn't sound naturally with a drumkit
108        - fixed EG1 modulation when attack or release is zero

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