We love this analog polyphonic synthesizer! DCO (digitally controlled oscillator) technology marries the ease and stability of digital with the warm, desirable sounds of analog. 32 factory programs and memory for an additional 32 user programs. 128-step, six part sequencer can be triggered by sync voltage from external drum machines and other devices. PG-200 Controller available for real-time control of all parameters and patches. Excellent #9 condition with one tiny dent at upper corner of face, almost invisible.
