This Synthi has the following mods: "Modifications include 3-way sync switches for OSC 1 & 2, a high/low range switch for OSC 3, a portamento knob for when it is being run by the sequencer, and a normal / one-shot envelope switch."

The test was carried out with the file midday of "One the Run" of Pink Floyd. The patch takes support on the preset bass 3 for the reading or the recording midi. The parameters of the filter were only modified."

"A music synthesizer module I designed ~1979. A cool digital/analogue hybrid that can generate either audio signals or envelopes using a 256-sample lookup table. To generate the table, it interfaces to either a computer, or to an XY panel I built (not shown) using four linear pots."
