The Pro/DGX was ARP's last preset-based synthesizer, produced between 1977 and ARP's demise in 1980.

Like the Pro Soloist, it features 30 presets and aftertouch. In fact, looks almost identical to the Explorer and Pro Soloist. However, there are some notable differences. The Pro/DGX was housed in a new steel chassis, which was somewhat sturdier than that of the Pro Soloist. Presets were now accessed via push-buttons, as opposed to the rickety switches of old.

The first run of this synth looks very much like the Pro Soloist in layout and colour scheme, though subsequently, it was produced using ARP's late 70's Orange and Black colour scheme, like the Quadra and Odyssey Mk-3.

The presets on the Pro/DGX are almost identical to those found on the Pro Soloist. However, it does sound slightly different, due to the implementation of a new filter design. Many describe the sound of the Pro/DGX as warm, and compare it favourably to its predecessor. However, some say it somehow sounds worse than the old model, perhaps less "organic".

The presets are as below:

Bassoon, English Horn, Oboe, Clarinet, Flute, Tuba, Trombone, French Horn, Trumpet, Cello, Violin, Bass, Piano, Banjo, Fuzz, Guitar 1, Buzz Bassoon, Sax, Space Reed, Telstar, Song Whistle, Noze, Pulsar, Comic Wow, Mute Trumpet, Steel Guitar, Harpsichord, Space Bass, Steel Drum, Country Guitar, Fuzz Guitar 2
