The enclosed file contains a sample plus a KB3 Program. Following is an explanation from the engineer that created this file:

It contains a KB3 program where the upper half of the tone wheels use a sample created by layering and detuning the ROM sine wave, then resampling. It sounds very rich and animated without any effects or Leslie simulation.

Here is an excerpt from Keyboard Magazine that got me thinking about this:

"Some Model B Hammonds that preceded the B-3 featured a chorus generator, which was similar to the tone-wheel generator except it was half the width and had only a single row of tone-wheels. For every note in the upper half of the main tone-wheel generator, the chorus generator produced one tone a few cents flat and another a few cents sharp."....."Since the tone-wheel generator was so expensive to manufacture, the company chose to use [the scanner vibrato/chorus] in favor of the chorus generator technique."

When I read this I realized I could do something similar, since the KB3 model uses samples for the upper tone wheels. The attached file is my first attempt at this technique, and sounds very cool. I doubt it sounds anything like the Hammond chorus generator; actually it sounds a bit like a slow Leslie, but of course only on the upper tone wheels.

I'm passing this along partly to point out the power of creating your own tone wheel samples. Ideally the KB3 model would let you use samples for *all* the tone wheel generators, but it's not possible.
