The first synth I got familiar with was the Moog Prodigy, back in summer of 1981. I rented it for over a month, didn’t want to return it to the music shop.
Great demo! They all sound slightly different. and all great! I wonder if the rounded wave forms in the rogue and prodigy are from age or by design. You can actually do contoured osc syncs on the minitaur and sirin as well: change the lfo type to filter env, apply modulation to osc 2 only, turn on hard sync.
