ARP Pro/DGX – Synthesizer – USA – 1977-1980 – Fully Functional


The ARP Pro/DGX is a classic monophonic analog synthesizer produced between 1977 and 1980 by ARP Instruments, USA. Known for its instantly recognizable preset sounds and expressive aftertouch, it was a staple for many keyboardists in the late 1970s and early 1980s.

This unit offers 30 built-in presets, ranging from orchestral instruments (trumpet, violin, flute) to vintage synth textures (fuzz guitar, space reed, bass). With polyphonic aftertouch control over vibrato, brilliance, volume, and pitch bend, the Pro/DGX allows for a surprisingly expressive performance despite being a preset-based synthesizer.
