Hopefully someone can help here. Just received a used ER-301 in the mail and it’s fantastic of course, but it seems like the note scaling is off from any source. I’ve tried a Keystep, Nerdseq, and the MIDI/CV converter on my Niftycase and in order to get a “C” from a flat 3v or 5v I have adjust the tune knob up by 290 cents. Is there some setting I can’t find that would address this?
This is CV input on both IN and Ax jacks, both on a variable speed sample player and just a naked oscillator with no VCA or filter.
