MPI_AudioWavetable.h

//
// MPI_AudioWavetable.h
//
// Description:
//   A wavetable which holds sample data.  It's read by an associated
//   MPI_AudioWavetableSynth object.  It can be accessed by multiple readers at
//   once.
//   This is relatively hacky -- you shouldn't be able to tick a wavetable, but
//   you can tick this class.  We do it this way to avoid code duplication of
//   the file reading code and other stuff.  It'd be better to have a nicer
//   separation, though.
