Euro Atoner Kit

Build your own Atoner, with the Eurorack Atoner kit.

The Do-it-yourself kit includes all the parts necessary to build a fully-featured Eurorack Atoner. This is an intermediate-level kit, you need some prior experience, and have basic hand tools (flush snips, needle-nose pliers, small screw driver, wire stripper).


Harmonics are extracted from an on-board oscillator or external audio signal and outputed as audio or clock pulses. The Position knob sets the cut-off frequency, under which all frequencies will be stepped downwards along a harmonic sequence (octaves, 5ths, 3rds, etc) all the way to sub-audible clicking sounds. Thus, a scale or clock signal can be generated from a single tone.

Two CV inputs and their respective +/- Vary Amount knobs modulate the Position cut-off. The mix of the two CV inputs plus the Position knob is outputted on a CV jack, and another CV output jack provides a steady +10V clock pulse that is jumper-selectable to be a clock division of the audio output (/1, /2, /32, /64, or non-linear division).

The Eurorack Atoner consumes 60mA of power and occupies 16 H. P. of space.
