"It is essentially two six voice synthesizers in one case, that trigger two voice channels each for six voice polyphony. That means it has each single oscillator has its own filter, for a total of 12 filters. The filters and oscillators are the same parts found in the CS-80. Other unique features include:
A sine wave bypass which is not filtered, to get additional bass.Aftertouch, which can control the filter, pitch, and amplifier- independent of the mod wheel
A built in sequencer with both live recording and step recording
Voice channel A and B have separate outputs
Has a Hertz/Oct Gate output for controlling external monosynths
A "keycode" input which interfaces the keyscanner directly, which midi controllers do exist for
CV(foot controller) inputs for Filter, volume and modulation
The "Yamaha CS" ring modulator
Auto Glissando
Lowpass, highpass, and bandpass selection
String machine chorus, and leslie simulator
This keyboard has had its power supply completely rebuilt. All new transistors, diodes, op amps, and capacitors. Any resistors not within tolerance have also been replaced. This was a result of six year long period of teaching myself how to diagnose and repair electronics. I installed a connector well off of the power supply to more easily read voltages should future service be needed."
