Hi All !
Methinks it's more the "wobble" in frequency that makes analogue less
useful for FM . On an Oberheim Xpander one can do some weird fm
tricks, like the bells n such, but the osc's are not stable enough to
be predictable, so more "normal" sounds just do not happen . On the
Nord Modular, where phase is not specified either, very good DX
sounds can be done, but then, the osc's are digital, and won't move
unless told so :)
The Yamaha FM is in fact Phase modulation : the index into the
wavetable is increased or decreased according to the modulation
index, that is a scaled from an input sine . But this does amount to
frequency modulation .
My 300's are not built yet, so we'll see when they are ;-)
Bye for now .
Keep 'em oscillating :)
Hugo
