This auction is for a perfectly working Yamaha CS-60 synthesizer. There are no flaws with this synthesizer and every feature has been demonstrated in the video I linked to above. It has been professionally maintained and has just recently been tuned and calibrated.
MIDI has been installed and a unison modification has also been installed that is triggered via the Sustain II setting. These features alone cost $2,000 USD.
When unison is engaged, all oscillators are stacked on to the same voice. Any voices played simultaneously with the unison voice are subtracted from the unison voice. You can see and hear the unison feature demonstrated in the later part of the video I have uploaded. The button is for MIDI settings and the switch allows you to switch between MIDI LFO and front panel LFO.
The MIDI manual detailing all of the extra features can be found at the Kenton MIDI website.
