Ever wanted to invert an external oscillator's wave shape? For instance, take a sawtooth wave and invert it to a ramp shape. Here's how I achieved it with the Pro 2. Route the external oscillator into one of the Pro 2 Cv inputs. Use the Modulation Matrix and set that CV in (let's say CV Input #1) as the source and set the destination to a CV out (let's say CV Output #2). Run a patch cable from the CV Output (#2 in this case) to the input of the external synth. Give the modulation a negative amount and the shape of the waveform will be reversed. I just did this with my Werkstatt. I routed the sawtooth oscillator out from the Werksatt into a Pro 2 CV input. I then used the Modulation Matrix to flip the wave shape and sent the inverse signal back to the Werksatt input, via a Pro 2 CV output. You can even mix waveforms by sending the Pro 2 oscillators to the same CV output. Then route LFO's to the modulation amount and have some really cool movement going on. I love my Pro 2!!
Cheers.
