notes for myself

The renderer (and ReadSamples) is supposed to work like this:

• drain the internal buffer
• if the buffer is empty:
  • while sample quota is not met:
    • check if the queue is empty and return EOF if it is
    • pop all notes to be rendered up to the requested time (i.e. # of samples) in seconds
    • for each note (concurrently):
      • check cache and invoke the resampler
      • invoke the concatenator (wavtool) with the internal buffer + resampled note
      • write the result to the internal buffer

Resampler

resampler.exe <input wavfile> <output file> <pitch_percent> <velocity> [<flags> [<offset> <length_require> [<fixed length> [<end_blank> [<volume> [<modulation> [<pich bend>...]]]]]]]
flags:
    N : No formant filter
