Re: Note names in Midi Note Numbers?

[PMA]

Just in case: if it's the audio itself you're after (not necessarily
also printed score), then you might possibly consider Csound,
which can accept raw-number pitches -- as cycles per second
or as fractional (in decimal or duodecimal) octaves.

Csound is emphatically *not* user-friendly, though there are
less forbidding front ends (Cecilia, Blue, QTCsound) available.
MIDI output is possible.  All-told, however, compositionally/
conceptually you should expect a steep climb.
