MCO is a 6 HP compact digital oscillator. It has the following three waveform outputs.

• Wavetable output that can morph between 10 different waveforms
• Pulse output that produces a waveform in which the upper (+) side segment of a normal pulse wave is replaced with the above wavetable output (similar operation to the sawtooth wave PWM of Alpha Juno)
• Sub output of pulse wave one octave lower

The type input changes the segment to be replaced with the wavetable output in the pulse output, affecting the harmonics.

The resolution is 16 bits / 48 kHz, and it features a thick digital sound like Ensoniq and Kawai KX series in the early 90's.
