OK- bear with me, I’m trying my best to ask this as clearly as I can.
The Blofeld allows Envelopes (for example, the Amp Env) to be assigned as an “FM Source” to modulate an Oscillator.
I don’t quite understand how that works. The classic basic model of FM is two operators, with one being the carrier and other the modulator. But the modulator should have a frequency, which will significantly shape the timbre of the carrier (along with the amplitude of the modulator).
But, envelopes don’t have a ‘frequency’, do they?? So what is happening when you assign an envelope as FM Source?
