Buchla 259e is a system of two oscillators: a complex waveform generator and a modulation generator. The Principal Oscillator can produce signals within nine octaves. Two wavetables are used to construct the signals. Voices can be selected from banks:...
261e module generates sound by interaction of the two generators (principal and modulation). Principal oscillator generates a sine wave within the range from 27.5 to 7040 Hz. The base wave can be transformed into a more complex one with the help of a...
