What if Finale is set up to output a stretched scale, so that C is assigned 60, D is assigned 64, and E is assigned 68, etc., up to 83 for B-1/4#? Okay, so long as you stay within a single octave, you're golden. But Finale puts all the pitch classes together. That is, a C is a C, a D is a D, etc., so once you get back to C5, the Midi output value drops to 72.
Dennis,
The non-standard key signatures don't work that way. An octave is defined as having x tones, each tone is assigned to a midi pitch number mod x, with nominals (white keys) and accidentals distributed as you like. In this way pitch classes repeat at x midi pitch numbers.
The limitation here is the number of midi pitch numbers available. In tunings with 24 pitches/octave of less, this is not such a problem, but in tunings with more pitches, you will probably want to assign channels to higher or lower octaves to get a wider range. (In 31tet or 43tet, for real-time playback with InTun, I assign channels to additional instances of InTun, each with a different tessitura, i.e. Channels 1-16 an octave or two lower, Channels 17-32 at standard pitch, and Channels 33-48 one or two octaves higher).
