I saw this for way too cheap to not pick up, clean up, and give a good home.
Released in 1974, the Roland EP30 was the worlds FIRST velocity sensitive keyboard (so they say...).
I opened it up to give it the old dust bunny cleaning. Definitely related to the SH-1000, which was from around its time. Voice architecture is built around the LM3216 that the SH-1000 also uses. Holy resistors!
BARELY anything on this guy. Anyone else have any input on it? Its controls are definitely basic... You've got a pitch adjustment on the front, a volume knob which can be pulled out to turn OFF velocity sensing, a "tone" knob that (sounds) like a low pass filter, a bass volume knob, and vibrato controls for depth and speed. Voices available include a bass preset which can be played on the lower 1.5 octaves along with Piano I, Piano II, Harpsichord I, and Harpsichord II settings.
How does it sound? Like a 1974 analog piano. Interesting sounding? Yes, can be very crunchy, and sounds very very warm and classy with vibrato on, and a sustain pedal sustaining. I was thinking the velocity sensing on this thing had to be rather crude, but on the contrary its great. Still working awesome, and works very well with varying velocities.
