The MF-102 is a direct descendent of the original modular Moog synthesizers. It contains three complete modular functions,- a Ring Modulator, a voltage-controlled Carrier Oscillator, and a voltage-controlled dual-waveform Low Frequency Oscillator (LFO). All performance parameters are voltage-controllable, which means that you can use expression pedals, MIDl-to-CV converter, or any other source of control voltages to play the MF-102.
