Product Description
Buchla's legendary 257 and 281 analog synthesizers are considered classics of their genre, implemented in a wide range of musical applications. The Behringer ABACUS is modelled after these original instruments, featuring an array of linear, logarithmic and exponential triggered or continuous functions.
Modulate & Push The Tempo
The ABACUS can generate musical envelopes or LFO signals up to 25 minutes in length and as fast as 1 kHz. Designed for use with other modules, it also allows you to change the modulation depth, modulate backwards and create even more musical events by manipulating tempo.
Unlimited Creativity
By manipulating the ABACUS’ control knobs, incoming signals can be an amplified, attenuated, integrated or inverted for unlimited creativity. Totally unique and crazy warped effects like lag, slew or portamento can be applied to control voltages perfect for use with a sequencer, or synth keyboard. Up to 4 control voltages can be combined to generate even more complex modulations.
Eurorack Ready
ABACUS is designed to fit into a standard Eurorack case. Just connect the power cables to the power supply and mount the module using the included screws. This allows for ABACUS to be mixed with other synth modules for a truly unique set up.
