Modified Tue Aug 16 17:14:25 2005 UTC (18 years, 8 months ago) by schoenebeck
Original Path: linuxsampler/trunk/src/engines

* extensive synthesis optimization: reimplementation of EGs and LFO(s),
  removed synthesis parameter prerendering and the synthesis parameter
  matrix in general, splitting each audio fragment into subfragments now
  where each subfragment uses constant synthesis parameters
  (everything's still very buggy ATM)

Revision 729 - Directory Listing

* lscpserver: we now only use one instrument loader thread; commands for
  loading instruments in the background wait in a queue to be processed one
  by one to avoid possible race conditions and to improve I/O efficiency
* fixed possible race condition while streaming with multiple disk threads
  by using an own decompression buffer for each disk thread
* libgig: fixed some memory leaks caused by non virtual base constructors

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

can be selected at compile time (see Engine.h) will be configurable via
LSCP soon though

* Load Instrument patch applied; this patch makes the
  LOAD INSTRUMENT command to return immediately,
  almost/always with an OK response, while spawning
  the proper instrument file loading in the background.

* New INSTRUMENT_STATUS field on GET CHANNEL INFO result
  set; the instrument status value holds the load progress
  percentage if positive, otherwise a negative value is
  evidence of a load exception error.

* VERSION is now set to 0.2.

Revision 123 - Directory Listing
Modified Mon Jun 14 19:33:16 2004 UTC (19 years, 10 months ago) by schoenebeck
Original Path: linuxsampler/trunk/src/engines

* src/common: added template class 'optional<>' which can be used e.g. as
  return type whenever a value might be returned, but don't has to; this
  template class pretty much acts like a pointer of the given type, but is
  much more safer than a simple pointer
* src/audiodriver: added static class AudioDeviceFactory to create audio
  devices at runtime by using a string and to obtain driver informations
  of drivers at runtime, driver classes should simply use the macro
  REGISTER_AUDIO_OUTPUT_DRIVER(DriverName,DriverClass) in their cpp file
  to register the driver to LinuxSampler (no changes needed anymore in the
  LS code to add a new audio output driver)
* src/drivers: added classes to dynamically manage driver parameters; there
  are two different kinds of parameters: parameters which are need to
  create a new device (DeviceCreationParameterX) used to e.g. create an
  audio output device or a MIDI input device and parameters which are only
  available at runtime, means when a device is already created
  (DeviceRuntimeParameterX) which will be e.g. used as audio channel
  parameters and MIDI port parameters
* src/linuxsampler.cpp: all registered audio output drivers will be shown
  on the console on startup
* src/network: implemented configuration of audio output devices via LSCP

  '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')

* 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 (20 years 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
