They were mainly all discrete transistor designs as op-amps at the time were very high cost. The discrete circuitry gave the modules a very distinctive sound and were used by artists like Keith Emerson, Stevie Wonder, Tangerine Dream and so many more, giving us some of the greatest records we’ve ever heard. Modular synths were a landmark development in electronic music and today, it’s about to get better.SPECIFICATIONS Controls Frequency 1 x rotary knob ±6 octaves / ±12 semitone, switchable Semitone / octave Rocker switch, ±1 VDC or ±6 VDC Width of rectangular wave < 10% to > 90%, 0 VDC to +6 VDC Signal Connections Frequency control inputs 2 x 3.5 mm jack, summed, 1 V/oct.
