Thanks, that you are open to the topic. I know it is stuff at the edge and asked by experimental musicians…
As far as I understand it, standard pitch variations can be transmitted relatively finely with the MIDI Tuning Standard
Besides the first byte which specifies the equal-tempered semitones two bytes (14 bits) specify the fraction of 100 cents above the semitone.
That should allow a very fine resolution: “(approximately 0.0061 cents) in size, which is far below the threshold of human pitch perception and which therefore allows a very accurate representation of pitch.”
However, there could be more complications which I am just not aware. But I think that is how Bitwig integrated it in their micro-pitch device.
I think it would be an additional feature that would make Oxi stand out from most other hardware sequencers.
