* 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

* 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

* 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

* implemented amplitude envelope generator
* src/voice.cpp: some .gig instruments still sounded detuned, I hope
  finally to have this fixed now

* implemented looping; RAM only loops (that is loops that end within the
  cached part of the sample) are handled in src/voice.cpp whereas
  disk stream looping is handled in src/stream.cpp and is mostly covered
  there by the new ReadAndLoop() method in class 'Sample' from src/gig.cpp

File length: 4639 byte(s)
Diff to previous 17

* 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

* implemented velocity->volume mapping: samples are now played back with a
  volume appropriate to the velocity of the triggered key, the velocity
  curve transformation functions (in src/gig.h) used for this are so far
  only an approximation to the ones from Gigasampler

File length: 4528 byte(s)
Diff to previous 12

* 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 12 - (view) (download) (as text) (annotate) - [select for diffs]

File length: 4393 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

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 (20 years, 5 months ago) by schoenebeck
File length: 4141 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
