I've recently come into possession of a number of back issues of "1/1 - the Journal of the Just Intonation Network" from the 80's and 90's. It's interesting how much content was devoted just to the topic of figuring out how to use non-12-tone-equal-temperament scales on the MIDI instruments of the time.
Most of one issue (volume 3 number 4 from 1987) was taken up with an article on how the author was able to reverse-engineer and modify the firmware of the Ensoniq Mirage to support the kind of microtuning he wanted.
