Details:
"The Odyssey has two oscillators that produce either saw tooth or square/pulse wave forms. Two notes can be triggered at once on the keyboard with one oscillator per note or both oscillators will be triggered when one note is played on the keyboard. There is a noise generator, random sample and hold, and portamento. A nice feature on this model is the PPC controller. The three white rubber pads on the left side above the keyboard will flatten, raise or introduce vibrato to the note depending on how much pressure is applied to the pads."
