What you got for your money though was two synthesisers in one, A fully polyphonic section and a monophonic synth section. Built like an absolute tank with thick gauge steel hinged front faceplate allowing full access to internal electronics. To build something like this these days would cost an absolute arm and a leg!!... One of the voices this synth is renowned for was the string type sounds. The voice was an absolute copy of a solina keyboard voice which was a lush deep warm phasing type voice that when used with effects can give a string sound to die for. All other voices are also usable. Mono section has the usual filter with resonance and frequency. You have the option of a fixed keyboard split allowing you to play a mono sound on the left and a poly on the right or vise versa. Can also play mono and poly patches layered. Pitch bend and portamento control, pitchbend control has it's control cap intact and the shaft is straight and responsive. Monosection has the option to play standard fixed tones or the option to modify using the filter or enevelope shaper also vibrato. The vibrato is a strange one because this effect is only available in the mono section with a preset vibrato delay. The poly section however has a control called 'animator' this was simply a chorus type effect that could be used on most of the poly section voices to thicken the voice for a warm polyphasic effect, quite effective though..."
