iiwusynth-0.2.2-2mdk.i586.rpm


- warbling bird bug
- test reverb
- test filter 
- test existing midi controllers
- comparison tests with sblive
- test and update audio drivers (dsound, oss, alsa, audioport (win,mac,linux))
- test midi drivers (alsa, alsaseq, oss, winmidi, midishare (win,mac,linux))
- man and info pages
- rpm (and db ?) package
- add chorus if I can find some clean code somewhere (?)
- brickwall limiter

- Add ~ completion to iiwusynth load command
- Bug: Loud overwhelming static heard with some instruments (filter
  effect?) I think that is probably the same problem affecting the
  warbling bird instrument (many other ones as well)
- Handling of notes seems strange, issuing a note-on WITHOUT a
  corresponding note-off will cause a stuck note (expected behavior) but
  issuing a note-on and note-off for the same note again will not turn it
  off (unexpected behavior?).
- An all notes off command for iiwusynth (noteoff with no parameters?)
  to get rid of pesky stuck notes


- test and finish bindings (fts (linux,win), java (linux,win), xtra)

DONE ------------------

- test and update audio drivers: oss, alsa, jack
- test midi drivers: alsa, alsaseq, oss, midishare (linux))

------------------

- sample rate != 44100
- chorus
- update configure to handle new asound.h location
- windows version
- director plugin
- java bindings
- direct access to audio buffer
- (configure) problems with readline
- soft clipping, compressor, limitor, or automatic gain control
- at sp creation: update params with current cc values
- velocity to filter frequency modulator
- default modulators (pitch bend, pan, volume)
- macintosh version


------------------


Design
------
- determine and protect critical regions
- check out atomic_inc and atomic_dec for flagging on/off of sp
- check out lock-free lifo for synchronization
- test for maximum cpu usage, and limit
- watchdog
- better debugging features and monitoring
  - MIDI events (driver status, received, errors)
  - Audio out (driver status, time, errors)
  - Debug message ()
  - CPU, memory usage
- better synth settings: iiwu_synth_attr or iiwu_synth_params
  o allow for optimization settings
    no key to filter modulator
    sample truncation, linear interpolation, 8 point interpolation, ...
    hardware acceleration
  o polyphony, buffer and queue size, ...
- load, reload, replace, and print info about soundfonts the way creative does it
- separate buffers for every channel, mix at last moment
   midi channel 1 goes to audio channels 1 and 2
   midi channel 2 goes to audio channels 3 and 4

Drivers
-------
- midishare
- alsa 0.5
- OMS on macintosh

DSP
---
- soft clipping, compressor, limitor, or automatic gain control
- add chorus
- review convex and concave curves
- improved float to int conversion
- 96kHz/24bits

Control
-------
- at sp creation: update params with current cc values
- velocity to filter frequency modulator
- default modulators (pitch bend, pan, volume)
- handle all continuous controllers
- more testing on voice stealing algorithm
- handles RPN and NRPN messages
- handle modulators
- possibility to select reverb type (concert hall, room, ...)
- possibility to select chorus type
- OpenSoundControl

Testing
-------
- create soundfont with basic wave forms [sine, square, triangle];
  make test midi file; compare with SBLive output; "regression" test
- compare performance with timidity

Installation & Info
-------------------
- web page
- man page, info page
- rpm package, debian package

Availability
------------
- windows version
- director plugin
- create a libiiwusynth library that doesn't necessarily depend on OSS
  or ALSA.
- make an fts package that links (statically?) with libiiwusynth
- compile on macintosh
- ladspa plugin
- alsa module
- csound opcode
- language bindings (Java, Python, Perl, Guile, ...)
- QuickTime Component
- CORBA interface? (Orbit, Mico)
- make netscape and ie plugin

Hardware
--------
- study ALSA interface, SBLive interface (OSS, win32)
- hardware detection
- specify hardware or software synth
