Desertf!sh sent me this nice video of him demonstrating a Pittsburgh Modular Synth. Very helpful if you're thinking about buying one of these, as it appears to be a bit of a rarity as far as demos go online. Also shows off the waveforms on the oscilloscope. From the man himself:
"I recently got a Pittsburgh Modular Foundation Synth, a beautiful euro rack mono synth. However, before I bought it i could not see any proper demos for it. Hence, I made a few demos for synth enthusiasts and anyone interested."
