ARP Pro/DGX
music synthesizer
The ARP Pro/DGX is a preset-based monophonic synthesizer manufactured by ARP Instruments, Inc. from 1977 until the company's demise in 1981.
Like its predecessor, the Pro Soloist, it features 30 presets and aftertouch. In fact, it 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 much sturdier than that of the Pro Soloist. Presets were now accessed via digitally latched momentary pushbuttons with LED indicators, as opposed to the more retro, flapper-style toggle switches used in the Pro Soloist.
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-1970s Orange and Black colour scheme, like the Quadra and Odyssey Mk-3.
The presets on the Pro/DGX are identical to those found on the Pro Soloist. However, it does sound slightly different, due to the implementation of a new filter design.

Why this record matters
The phrase “music synthesizer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 12, 2026. The linked authority identifier is Q3601144. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1977 and 1981.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
