ifn -- function table number
iphs (optional, default=0) -- initial phase (in samples)
ares -- output signal
kamp -- the amplitude of the output signal.
kcps -- the frequency of the output signal in cycles per second.
poscil3 uses cubic interpolation.
Here is an example of the poscil3 opcode. It uses the files poscil3.orc and poscil3.sco.
Example 280. Example of the poscil3 opcode.
