Tiptop Audio Buchla Model 296t Programmable Spectral Processor Module

The Tiptop Audio Buchla 296t module replicates Don Buchla's original Programmable Spectral Processor Model 296 featuring the same complex filtering, envelope following, vocoding, and more. 16 fixed-frequency filters all use the same inputs with three audio output sections.

The three audio output sections are Comb Filter Outputs, Attenuator Outputs, and Programmed Outputs. Comb Filter Outputs provide a sum of the odd and even filter bands. The Attenuator Outputs are used with the front-panel level control sliders providing summed outputs of all the bands and the odd/even bands as groups. Programmed Outputs (even, odd, all) are controlled by the Program Control, Programmed Spectrum Transfer, and Local Program CV controls.

The Program Control's frequency and width controls allow for focussing on specific frequency ranges at the Programmed Outputs with the option of voltage control. The Local Program Inputs are voltage control inputs for closer control of the level of each individual band at the Programmed Outputs. With the Programmed Spectrum Transfer you can connect the envelope follower outputs from the odd bands to the even bands' CV inputs. Used in conjunction with the Even and Odd audio inputs and outputs, this creates vocoder-like behavior.

TIPTOP AUDIO BUCHLA 296T FEATURES:

• Elaborate filter bank based on the Buchla 296 design
• Sixteen fixed filters with a host of audio and CV I/O
• Inputs for odd, even, and all bands
• Comb filter outputs produce sum of odd and even bands
• Attenuator outputs produce odd, even, and all filter summed outputs with levels controlled by front-panel sliders
• Programmed outputs respond to control voltage and programmed spectrum control/spectrum transfer functions
• Direct audio outputs for each filter band
• Direct envelope follower outputs for each band (with global response time selection)
• Capable of filtering, vocoding, and much more

BUCHLA & TIPTOP AUDIO 200 SERIES

Welcome to the Buchla & Tiptop Audio 200 series project. In this project Buchla has teamed up with Tiptop Audio to resume the production of Don Buchla’s 200 series and convert it to Eurorack standards. These extremely rare pieces of equipment made almost half a century ago are once again available, and this time to a wide audience.
