Buchla 281 Quad Function Generator
A quad function generator module in the Buchla 200 Series, built for complex transient generation and voltage-controlled timing.
Overview
The Buchla 281 Quad Function Generator is a modular synthesizer module in the Buchla 200 Series. It replaces the earlier models 280 and 284 and takes over their jobs with more features. It has four independent function generators. Each one puts out control voltages for modulation and sequencing. It can generate ADSR envelopes, and it can also run in Low Frequency Oscillator (LFO) mode.
Specifications
| Time range | .001 seconds to 5 minutes |
| Function generators | Four independent |
| Triggering | Each generator can be triggered independently |
| Envelope modes | ADSR envelope generation, LFO mode |
| Voltage control | Voltage control over attack and decay times |
| Outputs per channel | End of Cycle (EOC) and Sustain Gate outputs |
Design
The 281 has independent voltage control of timing, quadrature outputs, internal looping for repetitive function generation, and combining networks for building complex transient functions. It also has remote control capability, so it can work with digitally aided systems.
Context
The Buchla 281 replaces models 280 and 284 in the 200 Series lineup. The 281e is a modern, digitally controlled version of the 281. It works with all Buchla 200e systems and recalls all parameters digitally over the 200e bus.
