MFB Synth

The MFB SYNTH is a monophonic synthesizer with a pure analogue sound path, including voltage-controlled VCOs, VCF and VCA.

The MFB SYNTH is a monophonic synthesizer with a pure analogue sound path, including voltage-controlled VCOs, VCF and VCA. The module is controlled by MIDI or the integrated step sequencer that can store up to 15 sequences with up to 32 steps. Here are the details of the Synthesizer:

The VCO section consists of 3 VCOs, which are internally addressed with control voltage (V/Oct). Available waveforms are sawtooth, rectangle and triangle. The octave switch selects between 4', 8' and 16'. VCO 2 and VCO 3 can additionally be fine tuned over a range of + / - one octave.

syn2The VCF is a 24 dB lowpass filter. It offers the famous four pole cascade, developed by Bob Moog.

The cutoff will control the frequency, Emphasis will control the resonance up to self oscillation. Both VCF and VCA offer envelope generators with Attack, Decay, Sustain and Release, whereby Decay and Release share one controller and a switch.

VCO 3 can be used as a third oscillator or as an LFO. When used as a LFO it modulates VCO 1 and VCO 2 and/or the VCF.
