Revision 775 - Directory Listing
Modified Wed Sep 21 14:30:43 2005 UTC (18 years, 7 months ago) by schoenebeck

Modified Thu May 19 19:25:14 2005 UTC (18 years, 11 months ago) by schoenebeck

  prefix and will be placed into auto generated config.h file.

Revision 551 - Directory Listing
Modified Tue May 17 18:16:54 2005 UTC (18 years, 11 months ago) by schoenebeck

* Implemented MIDI program change as general, engine independant solution.
  The program number will determine the sampler channel to which the MIDI
  device will be connected to and the given MIDI channel defines on which
  MIDI channel that sampler channel should listen to. Also the program
  change will disconnect probably established connection from the previous
  program change event.

Revision 504 - Directory Listing
Modified Tue May 3 00:37:35 2005 UTC (18 years, 11 months ago) by schoenebeck

Revision 412 - Directory Listing
Modified Sat Feb 26 22:44:51 2005 UTC (19 years, 1 month ago) by schoenebeck

  not per EngineChannel instance)

Revision 411 - Directory Listing
Modified Sat Feb 26 02:01:14 2005 UTC (19 years, 1 month ago) by schoenebeck

* design change: using now one sampler engine instance and one disk thread
  instance for all sampler channels that are connected to the same audio
  output device (and are using the same engine type of course)
* added EngineFactory / EngineChannelFactory to remove the annoying build
  dependencies e.g. of the lscpserver to the actual sampler engine
  implementations
* bumped version to 0.3.0 (current CVS state is still quite broken,
  previous, stable CVS version was tagged as "v0_2_0" and is also available

  create multiple JACK audio output devices simultaniously for LS

which returned their values without being encapsulated into apostrophes,
fixed return values for 'DeviceRuntimeParameterBool' and
'DeviceCreationParameterBool' to be returned in lower case (as defined in
the LSCP documentation)
* src/network/lscp.y: key value pairs now also allow strings (without
spaces) to be not encapsulated into apostrophes (e.g. foo=bar instead of
foo='bar')
* src/linuxsampler.cpp: show on the console which TCP port the LSCP server
is using

Revision 212 - Directory Listing

Revision 207 - Directory Listing

Revision 202 - Directory Listing
Modified Tue Jul 13 22:17:10 2004 UTC (19 years, 9 months ago) by schoenebeck

Revision 174 - Directory Listing
Modified Tue Jul 6 03:27:38 2004 UTC (19 years, 9 months ago) by senkov

Revision 128 - Directory Listing
Modified Tue Jun 15 03:19:30 2004 UTC (19 years, 10 months ago) by senkov

* Remove calls to pure virtual from constructor of base class
 to avoid runtime failure. InitWithDefault() will have to be called
 from the constructor of the class where virtuals are implemented.

Revision 123 - Directory Listing
Added Mon Jun 14 19:33:16 2004 UTC (19 years, 10 months ago) by schoenebeck

* 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
