- Faithful revival of the Buchla Quad Function Generator Model 281 in Eurorack format
- Formatted for Eurorack height in a longer module, with minimal adjustment to functionality
- Four identical function generators to produce envelopes and LFOs
- Entire unit sends and receives Eurorack level signals via standard 3.5mm jacks
- Attack and decay times both range from 1ms to 10 sec, each with CV input (longer times available via external CV)
- Trigger button and input activate the function generator
- Mode switch determines how function generator acts to triggers and gates (Cyclic, Transient, and Sustained)
- Cycle CV input enables and gates cycling
- Per channel function generator output and end of decay trigger output
- Quadrature mode to enable paired generators with functions shifted by 90 degrees of each other
- Adjustable analog OR functionality for creating complex envelope shapes

Tiptop Audio Buchla Model 281t
Quad Function Generator 281t
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.
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.
Cycle jack enables the cycling of the corresponding function generator using a gate signal.
Trigger button enables the manual triggering of the function generators.
A switch selects one of three modes:
- Transient
- Sustained
- Cyclic.
The time range for both Attack and Decay is from .001 to 10 seconds.
In the 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.
