Stars and Stripes Forever transtuned to 12 of 27 from hemifamity27 – marching band sans percussion.
The master tuning is here.
The midi file that I found is of medium quality and this is decidedly a demonstration piece – this tune was chosen because it is a favorite of Gene’s. To get around having to transpose each note individually or as a pitchclass I use the method of picking 12 notes out of the 27 note set and used that to retuned Garritan Concert and Marching Band samples. The actual tuning is listed below. I think it notable that the rather large deviations from 12 equal, where each step is exactly 100 cents, is not very evident if at all.
12 of (3/2)^9 * (10/9)^3 hemifamity tempered
