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
