Droneo 1.3 counting in gray code

More Droneo 1.3 sneak - peak upcoming audio . it goes through all 256 combinations of the eight "reeds", in gray code order. Thus, it sounds a little shifted compared with the usual binary order. Gray code is counting with the property that only one "bit" changes with each iteration. so instead of: 000,001,010,011 , where fro 001 to 010 two bits change, gray code counts: 000,001,011,010 so that exactly one bit changes each time. It's like counting fractally, I used to say in college back in the 17th century. There are 256! ways to count from 0 to 255, but these two are pretty interesting ways.
