MOTM

Way back in the 70's I used to get a pitch shift effect by driving an analog delay with a sawtooth control voltage. It's quite crude, and the saw needs to be pretty pure (not too hard with an MOTM oscillator driving it), and it has to be "positive-going" (back then we called 'inverted' sawtooths 'ramps' but that distinction seems to have faded with time and the terms are used interchangeably now). You could hear imperfections in it, but I thought it was kinda cool at the time.
