200e USB Firmware Card

Occasionally, we make changes in a module’s firmware to fix software bugs or to add new features. The little firmware cards we used to supply with modules have been replaced by the USB Utility Card. With a Macintosh computer running OS10.5 or higher, you can load the...

297 Infinite Phase Shifter

The Model 297 Infinite Phase Shifter displaces the phase of an applied signal by up to 1,800 degrees, depending on frequency and number of stages selected. The phase-shifted signal may be combined with the original to create a moderately warped comb filter with...

296e Spectral Processor

A 16 channel bandpass filter with built-in analysis and synthesis capability, the 296e can function as a real time performance filter, a programmable compound equalizer and even as a spectrum transferring vocoder. Center frequencies are selected to complement the...

292h Dual Lowpass Gate

2 independent vactrol-based gate/filters in the classic Buchla format. This is a 2-channel equivalent to the 292e and has all the features and compatibility you would expect in a module. Each channel can process audio as a low-pass filter, a VCA or as a combination...

292e Quad Dynamics Manager

The 292e Quad Dynamics Manager is functionally identical to the original 292, with the addition of two new features: Velocity control and parameter storage. The 292e sports four independent voltage-controlled amplifiers. Each has a signal input and output, a control...

291e Triple Morphing Filter

The 291e Triple Morphing Filter comprises three voltage-controlled bandpass filters that can operate independently or in parallel. The amplitude, center frequency, and bandwidth of each filter may be independently voltage-controlled, and each can be modulated with...

285e Frequency Shifter / Balanced Modulator

The top section of the dual-function 285e performs frequency shifting; up and down outputs are simultaneously available. The reference frequency can be externally applied or internally generated; the latter can be voltage-controlled and modulated using FM. The bottom...

281h Dual Function Generator

2 independent envelope generators with VC attack and decay, with ability to cycle and perform as a LFO. This is equivalent to 2 channels of the 281e and is compatible with 200e systems as well. Purchase through authorized Buchla...

281e Quad Function Generator

The 281e Quad Function Generator comprises four function generators organized in two pairs. All four generators can operate independently or can be linked in pairs to generate more complex output voltages. A momentary switch selects one of three modes: Transient,...
