Buchla x Tiptop Audio Model 281t Quad Function Generator Eurorack Module

Description

Experience The Legendary Buchla 200 Series Revived with the Buchla x Tiptop Audio Model 281t Quad Function Generator Eurorack Module

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 will once again be available, and this time to a wide audience. Each module will be produced separately as production schedules and component availability allows.

The Model 281t is a careful Eurorack recreation of Buchla’s “281e Quad Function Generator” module, a piece that continues to be a Buchla brand staple. The 281t 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. Upon receiving a pulse, a generator’s output voltage ramps up to 10V at a rate determined by the sum of an applied control voltage and the setting of the attack time knob. When in Sustained mode, the voltage will stay high as long as the input pulse is maintained; when not in the Sustained mode, or when the input pulse terminates, the output ramps down to 0V at a rate determined by the sum of the decay cv in and the setting of the decay knob.At the end of the Decay segment, a transient pulse appears at the pulse output. If the 281t is in Cyclic mode, the cycle now repeats.

Inputs, Outputs and Controls

• Trigger Button – Enables the manual triggering of the function generators
• Cycle Jack – Enables the cycling of the corresponding function generator using a gate signal
• Mode Switch – A switch selects one of three modes: Transient, Sustained, and Cyclic
• Attack and Decay – The time range for both is from .001 to 10 seconds
• Quadrature Mode – Generators A and B (or C and D) operate in tandem with their functions shifted by ninety degrees in relation to each other
