Revision 33 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Mon Feb 16 19:30:42 2004 UTC (15 years, 3 months ago) by schoenebeck
File length: 5894 byte(s)
Diff to previous 32
* 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


Revision 32 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Tue Feb 3 13:21:19 2004 UTC (15 years, 3 months ago) by schoenebeck
File length: 6483 byte(s)
Diff to previous 31
* introduced time stamped events
* implemented jitter correction
* added pitchbend wheel support
* src/audiothread.cpp: using voice pool instead of a voice array, makes
  voice allocation more efficient and code more readable
* src/rtelmemorypool: redesigned, added some new methods and pool is now
  derived from list


Revision 31 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sun Jan 18 20:31:31 2004 UTC (15 years, 4 months ago) by schoenebeck
File length: 6107 byte(s)
Diff to previous 30
* 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


Revision 30 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sun Jan 11 16:43:54 2004 UTC (15 years, 4 months ago) by schoenebeck
File length: 5819 byte(s)
Diff to previous 20
* implemented amplitude envelope generator
* src/voice.cpp: some .gig instruments still sounded detuned, I hope
  finally to have this fixed now


Revision 20 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Thu Dec 25 00:02:45 2003 UTC (15 years, 5 months ago) by schoenebeck
File length: 5792 byte(s)
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) (as text) (annotate) - [select for diffs]
Modified Sun Dec 7 05:03:43 2003 UTC (15 years, 5 months ago) by schoenebeck
File length: 5660 byte(s)
Diff to previous 15
* 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 15 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Sun Nov 23 21:16:49 2003 UTC (15 years, 6 months ago) by schoenebeck
File length: 5392 byte(s)
Diff to previous 13
* rewrote sustain pedal handling: instead of just queuing the note-offs I
  added a sustain pointer for each midi key which starts to point to the
  first active voice on the respective key and increments to the next voice
  on the key when a note-off arrived, the release velocity value will
  immediately be stored in the respective voice object (this also fixes the
  segmentation fault issue when the sustain pool was full)


Revision 13 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Fri Nov 21 15:07:23 2003 UTC (15 years, 6 months ago) by schoenebeck
File length: 5545 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) (as text) (annotate) - [select for diffs]
Modified Sun Nov 16 19:01:50 2003 UTC (15 years, 6 months ago) by schoenebeck
File length: 5530 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) (as text) (annotate) - [select for diffs]
Modified Tue Nov 11 23:30:47 2003 UTC (15 years, 6 months ago) by senoner
File length: 5561 byte(s)
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) (as text) (annotate) - [select for diffs]
Added Wed Nov 5 14:47:10 2003 UTC (15 years, 6 months ago) by schoenebeck
File length: 3458 byte(s)
* transition from plain Makefile to autotools, source files moved to src/
* configure.in: added test for x86 architecture
* src/voice.h: x86 specific asm optimization for double to int casts only
  if compiling for x86 architecture
