[CM] Snd 9.0

[Bill Schottstaedt]

Snd 9.0

I discarded the old recorder and the track support, and completely 
revamped the virtual mix support -- enough changes to warrant a new 
major version.


the recorder:
  completely discarded the old recorder and its functions -- these are gone:
    recorder-autoload
    recorder-buffer-size
    recorder-file
    recorder-file-hook
    recorder-gain
    recorder-in-amp
    recorder-in-chans
    recorder-in-data-format
    recorder-in-device
    recorder-max-duration
    recorder-out-amp
    recorder-out-chans
    recorder-out-data-format
    recorder-out-header-type
    recorder-srate
    recorder-trigger
    vu-in-dB
    vu-size
  due to hardware troubles, I haven't fully tested the new recorder.

tracks:
  removed:             replacement:
    copy-track
    delete-all-tracks     silence-all-mixes
    delete-track          silence-mixes
    filter-track
    free-track
    lock-track            
    make-track
    make-track-frame-reader 
    make-track-sample-reader
    mix-track
    play-track            play-mixes
    read-track-frame 
    read-track-sample
    retempo-track         scale-tempo
    reverse-track         scale-tempo by a negative scaler
    save-track            save-mixes
    set-all-tracks        sync-mixes
    track                 (now any list of mix ids) -- syncd-mixes follows the mix-sync value
    track->sound-data     (see save-mixes)
    track->vct            (see save-mixes)
    track-amp             scale-mixes
    track-amp-env         env-mixes
    track-chans
    track-color           color-mixes
    track-dialog-track
    track-frames          mixes-length
    track-maxamp          mixes-maxamp
    track-name
    track-position        move-mixes
    track-property
    track-sample-reader?
    track-speed           src-mixes
    track-speed-style
    track-tag-y           set-mixes-tag-y
    track-tempo           scale-tempo
    track-track
    track?                (now just a list)
    tracks
    transpose-track       transpose-mixes
    view-tracks-dialog

  removed track-colors.scm and mix-menu.scm

  removed all track-related arguments from functions such as mix-vct, mix, and
    mix-region

  removed tempo-control-bounds

  completely rewrote the virtual mix support:  these are gone:
    copy-mix
    delete-mix (set mix-amp to 0.0)
    mix-chans (each mix is one chan in -> one chan out)
    mix-inverted?
    mix-locked?
    mix-speed-style
    mix-tag-position

  changed
    mix-frames -> mix-length
    delete-all-mixes -> silence-all-mixes
    pan-mix (mix.scm) and all its friends
 
  added 
    edit-properties
    edit-property accessor in extensions.scm
    mix-sync

    mix.scm:
      scale-mixes
      silence-mixes
      move-mixes
      src-mixes
      transpose-mixes
      color-mixes
      set-mixes-tag-y
      mixes-maxamp
      scale-tempo
      mixes-length
      save-mixes
      env-mixes
      sync-all-mixes
      syncd-mixes
      play-mixes

  moved mix-properties into C.

  "mix" function now handles one channel in and out and the position defaults to 0 (not the cursor)

the 1st arg to "play" can be a function that produces samples to be sent to the DAC, or
  controls other such processes -- see play-mixes in mix.scm for an example.
