Buchla Model 259t Programmable Complex Waveform Generator

Buchla Model 259t Programmable Complex Waveform Generator Oscillators:There are two oscillators: Modulation and Principal, both oscillators can be manually tuned via CV or Autotuned via ART. The Modulation Oscillator has a fixed Triangle waveform and a toggle selectable Signal output which can be a Triangle, Square or Sawtooth waveshape. It can be switched from LFO (Low-Frequency Oscillator) mode to a high audio-rate oscillator. Additionally, it can be configured to receive incoming 1V/OCT or ART signals. A CV output is also available for the Modulation oscillator. The Principal Oscillator has three audio outputs: a fixed Sine wave, a fixed Square wave and a Final output which provides infinite complex waveforms via the Timbre and Harmonics sections. The Principal Oscillator runs at audio rate but its frequency range can be driven higher or lower with CV. It can also be switched from 1V/OCT to ART. Both oscillators have a large Frequency control knob with a range of about 27.5hz which
