# Line 56  Version CVS HEAD (?) Line 86  Version CVS HEAD (?)
86      - Added new C++ API method Sampler::GetGlobalMaxStreams().      - Added new C++ API method Sampler::GetGlobalMaxStreams().
87      - Added new C++ API method Sampler::SetGlobalMaxVoices().      - Added new C++ API method Sampler::SetGlobalMaxVoices().
88      - Added new C++ API method Sampler::SetGlobalMaxStreams().      - Added new C++ API method Sampler::SetGlobalMaxStreams().
89        - Various "const" and "restrict" optimizations.
90        - all engines: add pan CC value to instrument pan parameter before
91          applying panning, instead of using two separate pan functions in
92          series (#182)
93        - added a lock guard class for exception safe mutex handling and
94          used it everywhere appropriate
95        - Immediately apply scale tuning changes to active voices.
96        - Exposed scale tuning to C++ API (along to the already existing standard
97          SysEx way).
98        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
99          and broken for ppc64. (Seq_cst loads and stores are actually not
100          used in LS, so the bug wasn't noticable.)
101        - lsatomic.h: added ARMv7 support
102        - Added support for multiple MIDI input ports per sampler channel (and
103          added various new C++ methods for this new feature / design change, old
104          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
105          as deprecated but are still there and should provide full behavior
106          backward compatibility).
107        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
108          unsafe and caused compilation error with clang 2.x).
109        - Bugfix: only process the latest MIDI program change event.
110        - Introducing the LSCP shell, which provides convenient control of the
111          sampler from the command line by providing LSCP aware features.
112        - VirtualMidiDevice: Added support for program change.
113        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
114        - VirtualMidiDevice: Added support for pitch bend.
115        - Aftertouch: extended API to explicitly handle channel pressure and
116          polyphonic key pressure events (so far polyphonic pressure was not
117          supported at all, and channel pressure was rerouted as CC128 but not
118          used so far).
119        - Added initial support for real-time instrument scripts. The script VM
120          code is shared by all sampler engine implemementations, however only the
121          gig file format currently provides support for storing instrument scripts
122          (as LinuxSampler extension to the original GigaStudio 4 format).

134        - handle special case when pan parameter in gig file has max or
135          min value
136        - Exclusive Groups: don't ever stop voices of the same note,
137          doesn't sound naturally with a drumkit
138        - fixed EG1 modulation when attack or release is zero
139        - Fixed support for 'aftertouch' attenuation controller.

306        - bugfix: line numbers in error messages were wrong after "#include"
307        - added support for float and 32 bit sample files

499          handler to "release" event handler.

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