257 (Black Corporation Reissue)

Dual Control Voltage Processor Model 257 by Black Corporation & Buchla

Each of the two identical voltage processors on the Model 257 takes three inputs and processes them in various to a single output voltage (for a total of six inputs x two outputs). Behind the elegant control panel, you’ll find a range of processing options, including addition, subtraction, inversion, scaling, and multiplication, as well as voltage-controlled transfer between two CV inputs.


• Sum two outputs with a third control output
• Attenuvertor pot on left, with voltage control
• Multiplier pot in the middle, with voltage control, which can sum or crossfade between two inputs
+5v switch offset adds to input level
• Output jack with LED signal level indicator
