[PD] frequency shifter

[hard off]

yeah i think the tutorial is for hardware.

>>I would simply use two
more triangle oscillators in place of the pitch shifters, and set the
frequencies using a bit of math based on the frequency of the first
triangle oscillator.<<

derek, this is the answer i had hoped for.  the snare drum is already
sounding really good.  i'm so surprised...

if you could help me with the math required, i would be very grateful.
