Don't think so, as I get the same effect just using the virtual
keyboard and fast Leslie.

I did some quick measurements on a 392 Hz (G) tone. The frequency
modulation index is way too high for anything of the physical
dimensions of a Leslie LF drum rotating at 330 rpm (that value was
confirmed by the measurements). And that is even without considering
diffraction effects which would result in an even lower modulation.

It's not meant as criticism. *If* I find the time (which won't be
in the next few months - I'll be writing DSP code but not for audio)
I'd be happy to contribute to this great project.
