AtomoSynth Tottem 2 Four-Voice Drum Synth Eurorack Module features ‘Raw’, Organic Sound

AtomoSynth has introduced Tottem version 2, a drum synth Eurorack module featuring four independent, all-analog percussion synth voices.

Two of the voices feature a full percussion synth, with triangle and square wave oscillator, an envelope for the “sweep” effect, one modulator with triangle and square wave as well as noise, also a decay envelope for the overall volume contour. These are very flexible generating from powerful bass drums, toms, clicks, all the way to “laser gun” and weird glitch sounds.

While the other two voices feature an oscillator with “metal” and square wave, a white noise generator, a mixer, and also a decay envelope. These are great to produce metallic sounds like hi-hats, crashes, cymbals, clicks, beeps, and all craziness in between. Combining the two synth voice types you can expand the possibilities even further for more complex sounds.

Lastly, an output mixer with individual level controls and outputs for each voice and a master output.

The developers say that the new Tottem has a raw, organic character and is not designed to emulate any drum machine, giving you “a new sound to enrich your percussion palette.”
