This module is an accurate reproduction of the Buchla 258, featuring two independent voltage-controlled oscillators that can be crossfaded from sine to saw and sine to square respectively. Each has one processing input, a frequency modulation input and a 1V/oct input. Waveshapes, as well as frequency, can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures. Known for it's organic waveshapes and extreme FM, the 258 is a special set of oscillators!
