I have been looking for a table long ago posted to the monome boards. It contains values associated with chromatic pitch shifting for rows in mlr, where 0.5 equals an octave down.

Does anyone have it or know it off hand?

I don’t have a table, but the equation is really simple:

2^(x/12)

where x is the number of semitones to shift.

The logic is that you want to multiply or divide by 2 every time you count up/down by 12.

Right! Brain fart. Thanks

I was feeling generous:

+12: 2.000 +11: 1.888 +10: 1.782 +9: 1.682 +8: 1.587 +7: 1.498 +6: 1.414 +5: 1.335 +4: 1.260 +3: 1.189 +2: 1.122 +1: 1.059 0: 1.000 -1: 0.944 -2: 0.891 -3: 0.841 -4: 0.794 -5: 0.749 -6: 0.707 -7: 0.667 -8: 0.630 -9: 0.595 -10: 0.561 -11: 0.530 -12: 2.000

That being said, I always used the just versions of the above when working with samples alone. These are even easier to calculate eg: P4 = 4/3 = 1.333, P5 = 3/2 = 1.500
