As requested:
It’s the world’s heaviest, clunkiest keytar. It’s a presets synth, but you can edit the sounds a little, I haven’t worked out if they can be saved. I don’t think so. Most of the controls have little effect. I guess it’s got a 2-pole filter, but it’s so gentle it might even be 1-pole. The resonance doesn’t.
I rather like it, to be honest. I’ve commented in the “most melancholy synths” thread that it’s quite sad. When the filter’s taken some top end off, it’s distant, dusty, cheap-sounding like an early 90s home keyboard and it goes out of tune. It reminds me of Boards of Canada.
