# Line 44  Version CVS HEAD (?) Line 60  Version CVS HEAD (?)
60      - implemented sine LFO, pulse LFO and saw LFO      - implemented sine LFO, pulse LFO and saw LFO
61      - experimental support for per voice equalization      - experimental support for per voice equalization
62      - added command line option --exec-after-init      - 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().
72        - Added new C++ API method Sampler::SetGlobalMaxStreams().
73        - Various "const" and "restrict" optimizations.
74        - all engines: add pan CC value to instrument pan parameter before
75          applying panning, instead of using two separate pan functions in
76          series (#182)
77        - added a lock guard class for exception safe mutex handling and
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        - Bugfix: only process the latest MIDI program change event.
94    
95    * Gigasampler format engine:    * Gigasampler format engine:

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