Not less than four frequency controls make tuning an ease:
- switch for LFO or VCO range
- octave rotary switch with six positions
- fine tuning control (approximately one octave range)
- coarse tune control (approximately one semitone range)
An 1V/octave input without attenuator is expanded by two scaleable FM inputs, one for linear and one for exponential frequency modulation. Using a jumper you can decide whether the module obtains pitch CV via the internal bus.
The VCO has a triangle core from which sawtooth, pulse and sine are derived. The wave forms are almost perfect and sans glitches.
The pulse width can be set with a control from 0 to 100% and of couse it can be modulated.
The A-111-2 features not only one but two inputs for oscillator synchronisation - one for hard and one for soft sync, which both differ in sound with the hard sync being more aggressive and richer in harmonics.
