Hope I've put this in the right section, seems like it's about object behaviour rather than patching.
I've noticed that the midi input object doesn't seem to have any kind of note priority (high/low/last), which wouldn't matter for sequencing but doesn't make for a very nice keyboard action. In fact monophonic patches play more like a polyphonic patch that only has one voice, with new notes voice stealing from old ones but not 'giving the voice back' after they're released.
I'm very new to Axoloti so perhaps I'm using the wrong object? If not, may I suggest a 'mono' MIDI input with an attribute to select note priority? I did do a forum search, but apologies if I missed something.
