Where ever possible I would prefer to always have the option of CV/gate. I don't use midi much as I find the 128 step quantising very limited.

Sounds interesting for me too. How should the input of the notes be
managed - if not via Midi (e.g. with several CV inputs) Or is Midi the only
option from your point of view Or a separate keyboard just for this
function (e.g. with small buttons only, like the buttons used in the A-107
or A-113)

Best wishes
