* added first two experimental voice stealing algorithms ('oldestkey' -
which just steals the oldest voice on the oldest key and 'keymask' - which
tries to pick the oldest voice on the same key where the new voice should
be spawned, if it fails it behaves like 'oldestkey'), the desired algorithm
can be selected at compile time (see Engine.h) will be configurable via
LSCP soon though

  almost/always with an OK response, while spawning
  the proper instrument file loading in the background.

Revision 64 - Directory Listing
Modified Thu May 6 20:06:20 2004 UTC (19 years, 11 months ago) by schoenebeck

* src/Sampler.cpp: fixed 3 stupid but fatal bugs that left in the rush (in
  method SamplerChannels(), CreateAudioOutputDevice() and
  CreateMidiInputDevice())
* src/network/lscpserver.cpp: implemented LSCP command
  'SET CHANNEL MIDI_INPUT_CHANNEL'
* src/Sampler.h: moved enums 'audio_output_type_t', 'midi_input_type_t'
  and 'engine_type_t' into the respective base classes
  ('AudioOutputDevice', 'MidiInputDevice', 'Engine')

Revision 57 - Directory Listing
Modified Sun May 2 17:45:43 2004 UTC (19 years, 11 months ago) by schoenebeck

* src/common/Thread.cpp: method StartThread() now blocks until thread
  actually runs, mlockall() will only be applied for realtime threads
* libtoolized liblinuxsampler
* initiated automatic unit tests against the LinuxSampler codebase
  (see src/testcases): already added a couple of tests for the Thread and
  Mutex classes, you have to explicitly compile the unit tests by running
  'make testcases' (you need to have cppunit installed though) and then you
  can run the console version of the test runner by calling
  'src/testcases/linuxsamplertest'
* src/Sampler.h: added API documentation

Revision 53 - Directory Listing
Added Mon Apr 26 17:15:51 2004 UTC (19 years, 11 months ago) by schoenebeck

* completely restructured source tree
* implemented multi channel support
* implemented instrument manager, which controls sharing of instruments
  between multiple sampler engines / sampler channels
* created abstract classes 'AudioOutputDevice' and 'MidiInputDevice' for
  convenient implementation of further audio output driver and MIDI input
  driver for LinuxSampler
* implemented following LSCP commands: 'SET CHANNEL MIDI INPUT TYPE',
  'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL',
  'SET CHANNEL AUDIO OUTPUT TYPE'
* temporarily removed all command line options
* LSCP server is now launched by default
