ilen (optional, default=0) -- the length (in samples) of the audio signal. If ilen is set to 0, it defaults to half the given note length (p3).
ain -- the input audio signal.
krep -- the number of times the cycle is repeated.
The input is read and each complete cycle (two zero-crossings) is repeated krep times.
There is an internal buffer as the output is clearly slower that the input. Some care is taken if the buffer is too short, but there may be strange effects.
Here is an example of the waveset opcode. It uses the files waveset.orc, waveset.sco, and beats.wav.
