Dual channel CV Processor (Modern)
The Model 156 Control Voltage Processor was developed as a front end for the dual oscillator of Buchla’s 100 series. The module is composed of two circuits, each can mix, offset, compress and invert signals. Red Panels Model 156M transfers the classic Buchla concept to the Eurorack world. Thanks to its overhauled design, the Model 156M is fully compatible with the 1v / octave standard. An exact clone of Buchla’s Control Voltage Processor is available under the name Model 156.
The CV processors of the Model 156M were primarily designed to alter pitch signals. Each circuit is equipped with two inputs. A potentiometer allows users to crossfade between control voltages coming from both connectors. Another knob can be used to introduce positive or negative offsets, meaning it is usable for transpositions. The third potentiometer compresses pitch CV signals and / or inverts them. Results are emitted via two outputs per CV processor.
