Thank you, John.
So you're saying "really - just try it!". I figured there must be
some difference between doing an LFO modulation and audio freq
modulation, I just can't figure out why there is. I think then that I
need to build and play around and experience.
Knowing this simplifies what I want to do. I already assumed a
capacitively coupled (or +/- sym.) modulation source, so thanks for
What about using noise as the modulation source? Would a constant
level of noise modulation allow those ghosty noise melodies?
