Nevertheless, Logic makes it easy to microtune its high-quality instruments, even if it is crippled, so if you already own Logic then you should definitely check it out. And large scales such as the 20-note eikosany, Harry Partch style just intonation, or large equal temperaments, are straight out unavailable. Stretched-octave scales like Indonesian Slendro and Pelog also can’t be tuned faithfully. You’ll miss the unimaginable cloud-like non-octave scales like Bohlen-Pierce and Wendy Carlos’ scales. These limitations restrict you to certain kinds of microtonal scales, and while there’s certainly room to explore within these limits, you’ll miss out on whole genres of microtonal scales that will blow your mind. The big drawback-and I mean huge-it only supports 12-note scales, those scales must repeat at the octave, and each note can only deviate from 12-tet from plus or minus 100 cents (1 semitone).

This online help file from Apple shows you how to find the tuning settings in Logic Pro X. Logic Pro supports microtonal scales, and can even load Scala files! This can retune all of its built-in instruments and synthesisers (it doesn’t apply to any AUs or VSTs you’re running). Although I’m a Windows-using peasant, I wanted to gather up some ideas to start you off. Seems like there are tonnes of Max OS X users who want to get into microtonal music but don’t know how to jump in.
