Hello, this is likely a silly question but I can't find the answer online---I have a backing track that I need to lower the pitch a half-step or so, possibly more, I've found the box with the pitch slider, at the top it says "Half Step", but when I use the slider it gives me numerical info and I have no idea which number(s) would represent the half-steps (since they're not whole numbers but fractions following a decimal point).
Is there perhaps a key I should be tapping on the keyboard that would lower pitch, say a half-step per tap?
Hope this makes sense & thanks in advance. :)
