So there are 10 bits of a bitmask that you can turn on and off?
It strikes me that you could use a knob to go from 0 (all bits off) to 1023 (all bits on). It would be quite hard to dial in a specific value, such as
0000100000, which would probably sound very different from
1111000000 even though they are adjacent values.
If you only want one bit on at a time, you could go for powers of two: 2^n with n = 0 to 9, ie: 0, 1, 2, 4, 8... all have one bit set, or none.
Otherwise @martinruss wrote a tutorial on making a toggle button in Gen, have a look at
