I believe that the MIDI standard allows for single-note real-time sysex
messages that can alter the pitch of any of the 128 note numbers.  A 3-byte
frequency resolution is possible which is a little better than one-hundredth
of a cent:

I also believe that the Scala software can re-tune a midi file according
to a microtonal scale using such single-note real-time sysex messages.

The Scala software contains example scales with 79 notes per octave
so your proposal of 1366 notes per scale may be feasible.

Unfortunately I do not experiment in this area so I cannot provide any
more detailed information.
