Quantizer: another idea that we've beat the life out of here! When this first
came up, maybe a year ago, there was a serendipity around Dave V.s suggestion
of programmable modes and tonalities. The most interesting, for me, was
Thomas H.s concept of "personalities" which could be programmed and later
indexed through. This would probably be more than a PIC could do, and I'm not
entirely sure what it would mean, but I'd like a quantizer like this as well!
