This really is a fantastic synth. It has 2 osc and 1 filter. It's pretty limited as far as waveforms go though, but it has polyphony! It came out in the 80s. I received it as a present from a beautiful girl at university called Helen. That was back in the early 90s. Today it has spent a bit of time in storage under the stairs where it turned out to be a bit damp, and it famously has this weird foam in the synth that dies and turns into goo after a while so 2 of the keys stick down. I should really open it up and see if I can clean it.
