Subject: FM stuff was :Re: '410 inches closer to reality......

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 :)
