To @dmirate: It’s Ableton. Believe it or not, different DAW’s and other music software can’t agree whether Middle-C is C3, C4 or C5, because of a vagueness in the MIDI specification. Only thing you can do is add an octave offset after the CV from the MIDI, and then maybe write an email to VCV support asking them to add a switch to the MIDI->CV modules.
