Custom wavetable instrument. It can use any number of wave files & interpolate between any two frames (single-cycle waveforms), linearly or completely randomly, while also automating the weighted average between them. This example uses 44 waveforms.

As always I'm impressed with the power & versatility of Csound - if you can imagine it, Csound makes it possible.
