Arp Pro-DGX

Released in 1977

The Pro-DGX is a thirty preset monophonic analog synth with digital controls. The 37-note keybed has aftertouch for volume, brilliance, vibrato, wow, growl, and bend effects - and even all at once if you desire! A few basic filter, envelope and LFO controls allow some tweaking of the preset sounds. Get your classic Tony Banks sounds with this unique Arp - no other synth sounds quite like it.
