[Csnd] k-rate cps to pch conversion

The Csound Mailinglist

Hey hey,
I was looking for a k-rate cps to pch converter. The only two opcodes that I could find were cps2pch and cpsxpch and they apparently only work at i-time.

oct fractions can easily be scaled to pch fractional range, but it is interesting. Is there a good reason for it?

Best wishes and thanks,

Jeanette

Like Dave, I usually prefer other tunings, but if 12-equal is your goal, there’s no need for a lookup table:

ibase = cpspch0\.00
koct = intkPch
kpc = frackPch*100
kfreq = ibase*2^koct\+kpc/12
