Behringer ABACUS Analog Music Computer for Eurorack

Buchla’s legendary 257 and 281 analog synthesizers are classics of their genre. In fact, you will hear them in a wide range of musical applications. The Behringer ABACUS takes its inspiration from these original instruments, featuring an array of linear, logarithmic and exponential triggered or continuous functions.

Modulate and Push the Tempo

The ABACUS can generate musical envelopes or LFO signals up to 25 minutes in length. Also, it can generate them as fast as 1 kHz. Designed for use with other modules, it also allows you to change the modulation depth, and modulate backwards. You can create even more musical events by manipulating the tempo.

Unlimited Creativity

By manipulating the ABACUS’ control knobs, incoming signals can be amplified, attenuated, integrated or inverted for unlimited creativity. Also, implement totally unique and crazy warp effects like lag, slew or portamento to control voltages. Specifically, it’s perfect for use with a sequencer, or synth keyboard. You are able to combine up to 4 control voltages and generate even more complex modulations.
