Features - 5 octave keyboard with full size, touch sensetive keys - built in stereo speakers - 20 drum rhythms - 32 voices - a sound editor function to allow you to change the preset voices - transpose - modulation and pitch bend wheels - 4 types of reverb - chorus - sustain - portamento - auto play - percussion sounds playable from the keyboard. On the back are 3 midi sockets - expression pedal socket - 3 other footswitch sockets (use unknown) - and stereo jack outputs, the right output doubling as headphone socket. 8-polyphonic, 4-part multitimbral PCM synthesizer workstation with a PCM drum machine. 3 OSC architecture without a filter. A sound is made of Attack Source (1 OSC) and Body Source (2 OSC). The Attack Source is basically a short transient sample like Roland D-50. The Body Source is a combination of 2 samples called Basic and Harmonics. They seem to be basically single-cycle waveforms, and some Harmonics waveforms includes 'Spectrum' type longer loops. The Basic sets the overall character of the Body Source, and the Harmonics determines the second waveform added to it. Harmonics volume works like a static filter. 2 Amp envelopes for Basic and Harmonics. They have ADSR relative change parameters. Both Basic and Harmonics have 2 LFOs for pitch and amp (that is, 4 in total), controlled by rate variation, depth, speed and delay. Auto bend can be set differently for both Basic and Harmonics. Portamento is also available, which was a rare feature for PCM synths in the 80s. Big custom LCD display with 10-step parameter graphics.
