forgot to change some things which was mandatory due to the recent
directory movements ('/src/audiodriver' -> '/src/drivers/audio',
'/src/mididriver' -> '/src/drivers/midi')

* 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

* 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',
* temporarily removed all command line options
* LSCP server is now launched by default

removed unnecessary dependencies

Revision 35 - (view) (download) (annotate) - [select for diffs]

Diff to previous 33
* implemented parser for the LinuxSampler control protocol (LSCP) by using
  flex / bison (where src/network/lscp.l is the input file for lex / flex
  and src/network/lscp.y is the input file for yacc / bison), parser and
  scanner can be regenerated by 'make parser'
* implemented LSCP network server (only single threaded so far), LSCP
  server will be launched if LinuxSampler was started with "--server" flag,
  implemented the following LSCP commands so far: "LOAD INSTRUMENT", "GET
* disk thread now started within the engine

File length: 11984 byte(s)
Diff to previous 31
* implemented bidirectional voice state transition, means voice state can
  switch arbitrary times between 'Sustained'<-->'Released' within it's life
  time, thus the release process of a voice can be cancelled
* src/eg_vca.cpp: extended envelope generator by additional states
  ('Attack_Hold', 'Decay_1' and 'Decay_2')
* applied patch from Vladimir Senkov which adds new command line parameters
  ('--jackout', '--alsaout' and '--samplerate')
* configure.in: fixed compiler warning

File length: 9494 byte(s)
Diff to previous 20
* Added JACK support: Audio rendering process is now callback based and
  independant of used audio output system. Interfaces to other audio output
  systems can be added by creating a class derived from abstract base class
  'AudioIO' and embedding the new class into linuxsampler.cpp.
* src/audiothread.cpp: applied patch from Vladimir Senkov which fixes
  hanging notes in conjunction with the sustain pedal

Diff to previous 18
* added command line switch --volume to set the global volume level
* added command line switch --inputclient to connect to an Alsa sequencer
  input client on startup (e.g. a MIDI port with a keyboard)
* added command line switch --instrument to select an instrument in case
  the instrument file provides more than one instrument

Revision 18 - (view) (download) (annotate) - [select for diffs]
Modified Sun Dec 7 05:03:43 2003 UTC (13 years, 10 months ago) by schoenebeck
File length: 7269 byte(s)
Diff to previous 13
* src/audioio.cpp: added support for Alsa 1.0.0
* src/audiothread.cpp: fixed several bugs in sustain pedal handling
* src/diskthread.cpp: fixed several bugs which occured under extreme
  conditions (endless loop in audiothread, freezing the whole application,
  outage of available disk streams)
* src/voice.cpp: fixed cubic interpolation (disabled by default; you can
  enable it by setting USE_LINEAR_INTERPOLATION to 0 in src/voice.h)
* src/configure.in: added check for Alsa version

Revision 13 - (view) (download) (annotate) - [select for diffs]
Modified Fri Nov 21 15:07:23 2003 UTC (13 years, 11 months ago) by schoenebeck
File length: 7269 byte(s)
Diff to previous 12
* src/voice.cpp: fixed bug which caused a voice not free it's disk stream
  when the whole sample was already played back and the voice was going to
  free itself resulting in outage of unused disk streams after a while
* src/audioio.cpp: implemented automatic fallback to ALSA plughw when the
  sound card doesn't support one of the hardware parameters
* src/linuxsampler.cpp: solved segmentation fault issue when receiving a
  SIGINT which was caused due to the fact that all threads entered the
  signal handler (there still seems to occur a segfault on some certain
  circumstances though)
* added print out of all-time maximum usage of voices and streams and the
  current number of unused streams
* src/thread.cpp: the StopThread() method will now block until the
  associated thread actually stopped it's execution

Revision 12 - (view) (download) (annotate) - [select for diffs]

File length: 6962 byte(s)
Diff to previous 10
* src/gig.cpp: fixed bug in decompression algorithm which caused it not to
  detect the end of a stream and let the disk streams reload forever also
  resulting in strange sounds at the end of disk voices (concerned only
  playback of compressed gig files)
* src/audiothread.cpp: deallocation of voices when they reached the end of
  playback (thus e.g. when sustain pedal is pressed and a disk stream
  reached it's end)
* various endian corrections needed for non intel systems
* introduced debug level, you can set the debug level and thus the
  verbosity of LinuxSampler in src/global.h

Revision 10 - (view) (download) (annotate) - [select for diffs]

Diff to previous 9
* src/audiothread.cpp, src/audiothread.h: added Sustain Pedal support
  implemented by postponing note-offs and leting multiple voices play
  on the same MIDI key.
* added the RTELMemoryPool Class which is a fast RT-safe memory allocator
  and list manger
* src/linuxsampler.cpp: added a voice and stream counter debug message

Revision 9 - (view) (download) (annotate) - [select for diffs]

  if compiling for x86 architecture
