"Two independent voltage-controlled oscillators, continuously tunable from 5 Hz to 20 kHz. Each has two processing inputs and a frequency modulation 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.
Processing inputs:
Processing control inputs permit multiple control of pitch without need of separate external processor.
Grey one is 1.2v/oct pitch input.
Processing controls:
Used to set desired range of frequency control. Expansion, compression, and inversion of scales are accomplished here.
Frequency modulation control:
For adjusting vibrato depth or creating clangorous or bell-like tones, rich in non-harmonic partials.
Output:
Signal amplitude is +4 dB. Output impedance is 600 ohms.
Oscillator frequency control:
Spans the audio spectrum of 5 Hz to 20 kHz with no range switching. (Applied control voltages can extend limits to .1 Hz and 30 kHz.)
Waveshape control input:
Waveshapes can be varied from sine to saw (osc 1) and sine to square (osc 2). Voltage control of waveshape enables powerful dynamic control of timbre."
