Did you look at this?

<http://www.research.att.com/~njas/sequences/A004718>

The formula is 'Write n in binary and read from left to write,  
starting with 0 and interpreting 1 as "add 1" and 0 as "change sign".'  
So a 13-bit number would exceed the number of semitones in an octave,  
if I understand your question correctly. You can check that in the  
"First 10,000 Terms," here:

(In fact, the leap between iteration 8190 and 8191 is quite large: -12  
-> 13.)

HTH, Charles
