Sismo Ona

   (0 reviews)

Sismo Ona has 4 independent sound generators, 2x synths (square wave / pulse / noise) and 2 x percussion (sine).

Generator 1: 2 squarewave oscillators/pulse/noise, with frequency adjustment, a decay effect and lfo (low pass frequencies oscillator)

Generator 2: 2 square wave osc/pulse. Also with frequencies adjustment, a distortion effect/filter and lfo.

The generators 1 and 2 can manually activate through temporary push button or by switch. Also possible to externally control by any gate/trigger/ cv (0-8v) signal when connected externally the signal to the lfo and then those mixed with external signal.

Generator 3: A sinewave oscillator, sound as a bass drums, low tom and drums with lfo.

Generator 4: A sinewave oscillator, sound as mid and high tom, bongo and woodblock with lfo.

The generator 3 and 4 can be activated manually by the push button or switch. Still possible to control externally by any gate/trigger/cv (0-8v) signal. When connecting externally the lfo signal is disabled. Each generator has an independent mono output.

Sismo ONA includes a multiple as the following configuration: 1 in x 4 out, 2 in x 2 out.
