Buchla - 256e Quad Control Voltage Processor

256e Quad Control Voltage Processor

The Model 256e Quad Control Voltage Processor is a resource for applying simple algebraic functions to control voltages. Each processor has two stages – the first stage provides for voltage-controlled panning between two inputs, and the second establishes a linear transformation between input and output. Additionally, a single breakpoint may be added to enable non-linear transformations.

The 256e controls are easily comprehended. A knob and/or a voltage controls the selection of input voltages. Additional knobs determine the output voltages for inputs of 0 and 10 volts. If a breakpoint is invoked, another pair of knobs sets the input and output values for the breakpoint.

Processes supported include scaling, inversion, addition, multiplication, weighted averaging, and voltage controlled selection. LED’s provide graphical representations of the transformation functions and of the output levels.

With a little help from a 225e or 206e preset manager, the settings of the 256e can be stored as part of a system preset.
