FMMF is a 4 operator FM (Frequency Modulation) synthesizer with 2 primary aims: Make FM synthesis as accessible and user-friendly as possible and use multi-stage envelopes and LFOs to make give lots of movement and modulation.
The waveforms, algorithms and envelopes in FMMF are all shown graphically, with the envelopes allowing dragging of nodes and clicking to change contour. Special attention has been paid to the envelopes to allow you to customise them in many ways, such as the number of stages, the contour of each stage, sustain and repeat points and tempo-sync. There are envelopes for the volume of each operator, the pitch, and the effects section (filter, distortion and delay) all with velocity and key tracking. Further modulation comes in the form of LFO’s for the pitch and effects section, with many LFO waveforms available, including my favourite, randomising.
For further sound design potential you have a low pass filter, a multi-mode distortion and a flexible delay (with comb delay option). An arpeggiator let’s you add even more movement to create rhythmic sequences.
• 4 Operator FM Synthesis instrument with 17 FM algorithms
• 11 different waveforms per operator, with note sync option
