Synthesis Type: FM
FM is a form of synthesis that relies on two (or more) oscillators
modulating each other to create a sound. Since its inception in the
1970s, FM synthesis has found its way into countless hit songs and
continues to be used today because of the wide palette of sounds it can
produce.
• Oscillators: Six basic waveforms (sine wave variations, plus
white noise).
• Filters: One filter. You can assign this filter’s type, cutoff,
frequency, and resonance.
• Envelopes: Up to eight envelopes for controlling volume,
filter, pitch, or other parameters.
• Low-frequency oscillators (LFO): Up to eight low-frequency
oscillators for controlling pitch, volume, or other parameters.
