You know, I’ve never really paid attention to it. My Kria ramblings are so random that I would have no idea if a note was “wrong” or not. That being said, I’ve never had it play out of scale when the mk4 is set to semitones. There is another MIDI-only algorithm but I haven’t experimented with it yet.
For reference, I’ve used the mk4 to send MIDI to a Slim Phatty (racked with my euro stuff), Minitaur, Bastl XOR, Mother 32, and a Volca FM. All with good results.
