I used to play microtonal music using the sysex messages of the MIDI
tuninqg starndard. Midish simply replayed the sysex messages generated
with another tool.

This requires the synth to support the corresponding standard (which
was my case). You could define custom events (short sysex pattens with
one or two parameters) and bind them to controllers to change the
tuning in real-time

Do you know which messages your synth supports?

Do you need to change the temperament in real-time?

Another approach that I tried (but gave up quickly) was to abuse the
pitch-bend controller to change the pitch of each note. This requires
each note to be played on its own channel; certain controllers can do
this, but not mines. This limited the number of notes, forced the same
patch for all channels, broke pitch-bend, so I didn't use this.
