Analog “electronic piano” - a similar sound to RMI or Crumar pianos, and a similar architecture and general vibe to “string machines” etc. circa the 70s.
It’s essentially an analog synth with preset tones rather than a full set of filter and envelope controls. The four presets are gradations from mellower, like an electric piano, to brighter, more like a clavinet. As a divide-down synth, the EP-30 is fully polyphonic.
This EP-30 was fully serviced and re-capped by the fine folks at Patchwork in 2024. All keys and functions work normally. Vibrato has both speed and depth controls. Velocity sensitivity (Roland claims this was the first velocity-sensitive electric keyboard ever made…?) can be turned on and off.
The integrated power cord folds into a compartment on the bottom. The lid snaps on to form a rugged, fully enclosed case, with minor nicks and scratches from traveling.
The price accounts for this instrument being fully functional and recently serviced (other EP-30 listings, e.g. on eBay and Reverb, note significant functional issues or don't vouch for the condition of the instruments.)
