Yes, and then I can scrap the stereo encoding again. I'd rather have it optional than required. And I agree, it would make more sense to pick eight notes and use them as a bitmap. We'd face the same problems as we did before with the harmonies, but that problem does not get any bigger or smaller so I don't see the point in not implementing it. Idea: parity information in the overtones? Not applicable if we go with Reed-Solomon codes, though. JC -- Too many emails?
