The Pro/DGX is a thirty preset monophonic analog synth based on the Pro-Soloist of the 1970's. The main difference is that the Pro/DGX had electronic switching (touch buttons) between its preset sounds whereas the older Pro-Soloist had circuit-based switching (rocker switches). It has 30 preset sounds to choose from, including Flute, Bassoon, Brass, Fuzz Guitar etc. Other features included pitch, portamento, vibrato, growl and wow effects. The keyboard has 37 keys with aftertouch sensitivity for volume, brilliance, vibrato, wow, growl, and even bend effects (all at once if you desire!). A few basic filter, envelope and LFO controls allow some tweaking of the preset sounds, however there is no memory to store your settings.

The Pro/DGX sounds slightly different than the Pro-Soloist however. The presets are virtually the same, but the Pro/DGX implemented a new filter design which some say sounds worse than the one used in the Pro-Soloist. Both synths refer to their single filter control (the filter cutoff) as "Brilliance". A few additional control sliders are available for the Volume, Portamento Time and Aftertouch Amount. Later on during its production, the Pro/DGX was released with the "Orange+Black" look of later ARP synths. It has been used by Tangerine Dream and Keane.

If you want to play early Genesis, and, as mentioned in another post, vintage Kansas, this is a good unit. I play Genesis and it definately get's THE sounds from Selling England through Wind and Wuthering. Amazing how toylike it is, and yet can cut through a loud band like a knife. In my case however, the J-Wires got really inconsistent within a couple months. Also, you have to be happy with the short keyboard and presets, there's really not much modification you can do... this is a special synth for a specific soundset, most likely for recreating 70's prog or jazz. For that, the thing CRANKS.

Hey there,

I found a posting of this for $90 and when I search it up on ebay someone is selling it for $2000 and another for $1500.

Do you know what the proper cost/value of the Arp Pro DGX would be?

Linda McCartney is seen playing a Pro-DGX on "So bad", from the movie "Give My Regards To Broad Street".
