The Buchla 256e Quad Control Voltage Processor is a quadrature control voltage centre. It provides two voltage inputs and a switch input per channel for controlling the panning, action and ranges of the input voltages. Ideal for diversifying modulation

The Buchla 257e is a complex control voltage processor that allows you to both add mathematical operation to the input voltages and their result and also slew three voltage signals at once. Allowing you to dynamically voltages on the fly.

The Buchla 261e Complex Waveform Generator is an advanced tone generator that provides voltage control over all major aspects of pitch, amplitude, and timbre. Since all of the modulation architecture is handled by analogue circuitry there’s no aliasing.

The Buchla 266e Source Of Uncertainty is the ultimate source for random voltages, noise and even store random voltages. Ideal for creating that musical chaos modular synthesis is well known for, random voltages can be used to triggering random events.

The Buchla 281e is a Quadrature Function Generator designed to provide either four independant voltages or two grouped pairs of complex voltages. The 281E also provides cycling voltages which can double as pseudo LFO’s or cycled envelopes if desired.

The Buchla 285e is a 200e series modular Frequency Shifter and Balanced Modulator, comprised of two sections that provides smooth frequency shifting and modulation of the frequency shifts occurring at its inputs, it also provide ring mod at its outputs.
