As an aside, division in binary is just chopping off the least significant (rightmost) bit. Doubling a number is only a matter of adding a 0 in the rightmost position and shifting everything to the left.
The fix is likely a one-line change for Elektron, possibly even a single character change. The (likely) issue leading to this problem is so common that there is a term for it: fencepost error.
Powers of two (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4098, 8192, …) are common in electronic music devices both because doubling and halving is a matter of shifting left and right and because digital devices tend to be designed to handle 8, 16, 32 or 64 bits at a time.
