Axo units are fractional, from -64.00 to 64.00 (or 0.00 to 64.00 but the same rules apply). You can set a dial to -54.68 or 15.01 or whatever cleans your fish tank. The resolution of all the “running” values/wires like LFOs or glide and so on is 27 bit. The ADCs are 12 bit and after denoising you still get some good fractional vslues.
