72      - implemented sine LFO, pulse LFO and saw LFO      - implemented sine LFO, pulse LFO and saw LFO
73      - experimental support for per voice equalization      - experimental support for per voice equalization
74      - added command line option --exec-after-init      - added command line option --exec-after-init
75        - Introduced new C++ API method:
76          EngineChannel::InstrumentFileName(int index)
77          allowing to retrieve the whole list of files used for the loaded
78          instrument on an engine channel (a.k.a. part). Some GigaStudio
79          instruments for example are splitted over several files like
80          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
81        - Added new C++ API method Sampler::GetGlobalMaxVoices().
82        - Added new C++ API method Sampler::GetGlobalMaxStreams().
83        - Added new C++ API method Sampler::SetGlobalMaxVoices().
84        - Added new C++ API method Sampler::SetGlobalMaxStreams().
85        - Various "const" and "restrict" optimizations.
86        - all engines: add pan CC value to instrument pan parameter before
87          applying panning, instead of using two separate pan functions in
88          series (#182)
89        - added a lock guard class for exception safe mutex handling and
90          used it everywhere appropriate
91        - Immediately apply scale tuning changes to active voices.
92        - Exposed scale tuning to C++ API (along to the already existing standard
93          SysEx way).
94        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
95          and broken for ppc64. (Seq_cst loads and stores are actually not
96          used in LS, so the bug wasn't noticable.)
97        - lsatomic.h: added ARMv7 support
98        - Added support for multiple MIDI input ports per sampler channel (and
99          added various new C++ methods for this new feature / design change, old
100          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
101          as deprecated but are still there and should provide full behavior
102          backward compatibility).
103        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
104          unsafe and caused compilation error with clang 2.x).
105        - Bugfix: only process the latest MIDI program change event.
106        - Introducing the LSCP shell, which provides convenient control of the
107          sampler from the command line by providing LSCP aware features.
108        - VirtualMidiDevice: Added support for program change.
109        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
110        - VirtualMidiDevice: Added support for pitch bend.
111        - Aftertouch: extended API to explicitly handle channel pressure and
112          polyphonic key pressure events (so far polyphonic pressure was not
113          supported at all, and channel pressure was rerouted as CC128 but not
114          used so far).
115        - Added initial support for real-time instrument scripts. The script VM
116          code is shared by all sampler engine implemementations, however only the
117          gig file format currently provides support for storing instrument scripts
118          (as LinuxSampler extension to the original GigaStudio 4 format).
119    
120    * Gigasampler format engine:    * Gigasampler format engine:

131          min value
132        - Exclusive Groups: don't ever stop voices of the same note,
133          doesn't sound naturally with a drumkit

442        - Added support for moving cursor left/right with arrow keys.
443        - Added support for built-in LSCP reference documentation, which will

541        - ignore missing LADSPA paths without ignoring valid LADSPA paths
542          (fixes #208)
543        - Fixed bug in LSCP grammar definition which caused a statement like
544          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
545          practically irrelevant, however it caused problems with the new LSCP
546          shell's auto completion feature).
547        - Fixed MIDI program change messages being ignored if quickly executed
548          after each other (fixes #231).
