The incorrect BP
By request I took Stuck at the Screaming Toll Booth and changed the tuning to 13 edo and for good measure included Bohlen Pierce as well since it is another native 13 note tuning. What amazes me is that the opening sounds identical in each tuning but by the middle of the piece the differences are very apparent,
especially with BP.
Apparently Aria has an issue with a period of 3/1 – every tuning I’ve tried so far with a 3/1 period plays incorrectly. The opening descending motive is transformed. Here is the midi file for you to try yourself. 20140502_13
