TRANSLATING FM TERMS
Here is a quick way to correlate the parameters of FM and subtractive synthesis when using a single FM oscillator pair.
Carrier Coarse Tuning = Overall Pitch. Carrier Level = Volume. Carrier Envelope = Amp Envelope. Modulator Coarse Tuning = Waveshape (e.g. the resulting timbre after FM is applied). Modulator Level = Filter
Cutoff. Modulator Envelope = Filter Envelope
