GENERAL DESCRIPTION :  

The 901A Oscillator Controller is the controlller section of the 901B Voltage Controlled Oscillator. The 901A panel contains the control voltage input jacks and potentiometer which vary the frequencies of all the controlled oscillators simultaneously. One controller may control up to 12 Oscillators. A bank of oscillators in which the intervals between the frequencies remain constant as the frequencies themselves are varied obviously has great musical value.
