The Pro/DGX is a monophonic analog synth with 30 electronically switchable presets and a 3-octave 37-note (C-C) keyboard with aftertouch. It was developed from the Pro Soloist. It is similar. The presets are electronically switchable as opposed to the Pro Soloist's circuit based switches. Its aftertouch sensitivity can be routed to pitch, vibrato, volume, brilliance, "growl" and "wow".
