[PD] frequency shifter

[derek holzer]

If all you want to do is generate two different simple waveforms that 
are shifted 175 and 224 Hz from the original, 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. I suspect this diagram could represent a hardware 
synth, where three oscillators is about the max you can get without a 
huge modular system.

Digital pitch shifting uses either FFT or other windowed procedures 
which sometimes doesn't always transpose a sound that smoothly and 
without some artifacts.

best,
d.
