257e Control Voltage Processor
Purchase through authorized Buchla Dealers.
The upper section of the module includes dual sets of high-resolution voltage inputs and outputs along with intuitive controls for performing mathematical operations on the voltages as they pass from the input to the output stages. Voltage levels are represented graphically by a grid, with the input and output levels independently settable, along with programmable break points that allow the user to precisely define the voltage level at any given point in the input-to-output signal path.
The lower portion of the module features three channels of dual-input voltage-controllable slew processors. The applications for slew-rate processing are myriad, from real-time dynamic adjustments of envelope segments to programmable vibrato/tremolo onset-delay to portamento. The inclusion of pulse outputs on each channel allows events, such as sequencer start/stop/advance, to be triggered as the skew voltages reach their maximum positive and negative values.
