Sample what you do and double track it or use a slap back delay and you should be able to approximate CS 80-type sounds with a little creativity. However, this is NOT a slamming bass-type machine. But rack that ribbon controller down to the left and you get monster bass rumble which threatens to embed any nearby drivers into your forehead and is just unlike anything you've heard on most any other machine. I'm impressing somebody with this machine's instantaineous wackiness. There is also an ext.
Experimentation is the order of the day.
My knowledgable colleague reveiwing this machine on this same site states that his is polyphonic. Touch sense is triggered by a light beam under the keys, so as soon as one key cuts it, it remains cut no matter how many other keys you press. However, on a machine from this time, this is a feature which makes this a musician's keyboard, rather than a tight monophonic bassline machine. THIS is what this machine excells at and probably why the dance fraternity seem to have determinedly ignored this piece of synth. Incidentally, using full sustain circumnavigates any perceived weediness in the oscillators to a startling degree, adding the aural effect of having an extra oscillator.
