The A-111,1 has a twelve octave range, producing frequencies from 1.6Hz to 177KHz, and produces four waveforms simultaneously (Pulse, Sawtooth, Triangle and Sine).
The frequency of the A-111.1 can be modulated by both exponential (1V per octave) and linear (Hertz per volt) FM (Frequency Modulation).
The pulse width is variable manually (0 - 100%) or by voltage control (Pulse Width Modulation - PWM) with a depth control. Soft and Hard oscillator sync input is available. Supply of this module is always in short supply, due to the difficulty in obtaining one of the component parts.
