Sticky Revision:

Revision 1043 - Directory Listing
Modified Wed Feb 7 21:02:04 2007 UTC (13 years, 2 months ago) by schoenebeck
* for now just set all notes off when receiving a MIDI coarse tuning
  message to prevent hanging notes when transposing while playing


Revision 1041 - Directory Listing
Modified Wed Feb 7 17:45:19 2007 UTC (13 years, 2 months ago) by schoenebeck
* handle MIDI coarse tuning messages (MIDI RPN #0 MSB, #2 LSB),
  currently lazy implementation, transpose value is simply added on the
  note on/off values instead only at the mandatory places, thus when
  altering transpose while playing, voices can unintendedly survive


Revision 1040 - Directory Listing
Modified Wed Feb 7 15:41:31 2007 UTC (13 years, 2 months ago) by schoenebeck
* bugfix: sampler crashed when trying to persistently map a not existent or
  corrupt .gig file ("MAP MIDI_INSTRUMENT ... PERSISTENT")
* behavior fix: reset FX send levels i.e. when receiving a MIDI "reset all
  controllers" message
* bumped version to 0.4.0.3cvs


Revision 1039 - Directory Listing
Modified Sat Feb 3 20:46:44 2007 UTC (13 years, 2 months ago) by persson
* EG fix: a release value of zero could cause noises or crash
* fix of previous thread safety fix, which in some cases locked the
  engine


Revision 1038 - Directory Listing
Modified Sat Feb 3 15:33:00 2007 UTC (13 years, 2 months ago) by persson
* playback is no longer disabled during instrument loading
* all notes playing on a channel that changes its instrument keep
  playing with the old instrument until they get a note off command
* new thread safety fix for lscp "load engine" and "set channel audio
  output device"


Revision 1037 - Directory Listing
Modified Tue Jan 23 20:03:22 2007 UTC (13 years, 2 months ago) by schoenebeck
* bugfix regarding FX Sends: when more than one sampler channel used FX
  sends, only the audio signal of the last sampler channel made it into the
  final output signal
* fixed small autoconf compilation issue on certain systems (complained
  about missing AM_PATH_ARTS macro)


Revision 1026 - Directory Listing
Modified Sun Jan 14 17:10:59 2007 UTC (13 years, 2 months ago) by schoenebeck
* extended response of LSCP command "GET FX_SEND INFO" to return the FX
  Send's MIDI controller and current send level and added two new LSCP
  commands "SET FX_SEND MIDI_CONTROLLER" and "SET FX_SEND LEVEL"
  respectively


Revision 1017 - Directory Listing
Modified Tue Jan 9 23:51:32 2007 UTC (13 years, 3 months ago) by schoenebeck
* create IDs for FX Send entities in a logical sequence on a per sampler
  channel basis


Revision 1012 - Directory Listing
Modified Sun Jan 7 15:52:36 2007 UTC (13 years, 3 months ago) by capela
* Fixed a memory leak due to EngineFactory::Destroy() not doing it
as an actual destructor and just removing the engine instance from
factory stock and all instances allocated via EngineFactory::Create()
never got delete'd and thus their destructors never called. This bug
was evident while having many mapped instruments and querying the
instrument status via GET MIDI_INSTRUMENT INFO command, eating up
system memory very quickly and never let it go.


Revision 1010 - Directory Listing
Modified Sat Jan 6 11:02:58 2007 UTC (13 years, 3 months ago) by persson
- fixed handling of MIDI volume change

Revision 973 - Directory Listing
Modified Fri Dec 15 21:40:27 2006 UTC (13 years, 3 months ago) by schoenebeck
* revised and extended MIDI instrument mapping feature to allow managing

Revision 958 - Directory Listing
Modified Wed Nov 29 19:48:38 2006 UTC (13 years, 4 months ago) by schoenebeck

  entry of its InstrumentManager


Revision 950 - Directory Listing
Modified Tue Nov 28 20:09:48 2006 UTC (13 years, 4 months ago) by persson

  on resonance.


Revision 783 - Directory Listing
Modified Sun Oct 2 14:40:52 2005 UTC (14 years, 6 months ago) by persson
* EG fixes: the length of "attack hold" stage was wrong. Release stage
  can now start before attack stage ends. Cancel release didn't work
  when sustain was zero.


Revision 781 - Directory Listing
Modified Mon Sep 26 10:17:00 2005 UTC (14 years, 6 months ago) by schoenebeck
* fixed event handling bug which was introduced by the recent synthesis

Modified Tue Aug 16 17:14:25 2005 UTC (14 years, 7 months ago) by schoenebeck
* 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
Modified Tue Jul 26 11:18:46 2005 UTC (14 years, 8 months ago) by persson
* improved filter cutoff calculation by adding support for the
  following gig parameters: Cutoff freq (used when no cutoff
  controller is defined), Control invert, Minimum cutoff, Velocity
  curve and Velocity range. The keyboard tracking now also scales
  cutoff frequency, not just resonance.


Revision 727 - Directory Listing
Modified Mon Jul 25 15:18:44 2005 UTC (14 years, 8 months ago) by schoenebeck
* fixed little inconsistency: LSCP commands 'LIST AVAILABLE_ENGINES' and
  'GET CHANNEL INFO' returned different names for the gig::Engine,
  returning now only 'GIG'

  connection


Revision 687 - Directory Listing
Modified Tue Jul 12 22:37:21 2005 UTC (14 years, 8 months ago) by schoenebeck

Revision 668 - Directory Listing
Modified Mon Jun 20 15:30:47 2005 UTC (14 years, 9 months ago) by schoenebeck

  note-off velocity.


Revision 617 - Directory Listing
Modified Wed Jun 8 21:00:06 2005 UTC (14 years, 10 months ago) by schoenebeck

  stack)
* voice stealing operates on all engine channels now
* limit voice stealing to MAX_AUDIO_VOICES thefts per audio fragment cycle

Revision 412 - Directory Listing
Modified Sat Feb 26 22:44:51 2005 UTC (15 years, 1 month ago) by schoenebeck
* gig::Engine: fixed silence (engine channels' events were not imported
  into the engine, fixed undesired creation of new gig::Engine instances
  (and disk threads)
* AudioOutputDevice: reverted behavior to render per Engine instance (and
  not per EngineChannel instance)


Revision 411 - Directory Listing
Modified Sat Feb 26 02:01:14 2005 UTC (15 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
  as source tarball)

Revision 385 - Directory Listing
Modified Thu Feb 17 02:53:45 2005 UTC (15 years, 1 month ago) by schoenebeck

* 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


Revision 249 - Directory Listing
Modified Mon Sep 20 00:26:40 2004 UTC (15 years, 6 months ago) by schoenebeck

Revision 133 - Directory Listing
Modified Fri Jun 18 14:29:02 2004 UTC (15 years, 9 months ago) by capela
* 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 (15 years, 9 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

  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 (15 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

  'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL',
  'SET CHANNEL AUDIO OUTPUT TYPE'
* temporarily removed all command line options
