BOOKER, a Hammond Organ simulator with Leslie, for GRAINS

I have posted BOOKER in my repository.  BOOKER is a 9-tonewheel Hammond Organ simulator with a Leslie. I built it to get familiar with Mozzi. It pushes GRAINS to its computational limit: so making further tweaks would likely result in going overboard computationally. I'd like it to be a bit brighter too, will work on that.

BOOKER is essentially a simple 9-harmonic additive synthesizer.  I am thinking I might whip up a variation of BOOKER which does a 9-harmonic additive drone with the various harmonics changing slowly in amplitude. Would be easy.
