ifn -- function table number
iphs (optional, default=0) -- initial phase (in samples)
ar -- 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.
