Programmable Waveform Generator Model 256 by Black Corporation & Buchla

The Buchla reissue of the Model 259 reproduces the original, unmatched sound with expanded tracking up to 10 octaves for greater sonic potential. The 259 features all-analog timbral circuitry, so it suffers none of the aliasing of digital wavetables. You get fully voltage-controlled modulation of pitch, amplitude with a multi-octave range owners of the original could only fantasize about.

Features:

Two oscillators, principal and modulation, with 27.5 - 7040 Hz range (.25 - 64 Hz LFO mode, or A1 - A9 quantized pitch mode)
3 waveshapes (saw, square, triangle) on modulation oscillator
Dedicated sine and square outputs
Modulation control with CV input, modulation index, and CV attenuverter
Phase lock, amplitude modulation, pitch modulation, and timbre modulation switches
220 Hz autotune feature with low/high range switch
Frequency modulation inputs with independent keyboard input and CV control (with attenuverter)
Even and odd symmetry and harmonics controls with CV inputs
Phase lock input with gain
1.2v/octave tracking, now with reliable response across a full 10 octaves
