So you mean by switching to x3/4 tempo you don’t get the 6/8 tempo, but rather 4/4 in triplets -> which would be triggering at a faster pace than 8ths in a 6/8?
I guess you could get a more realistic 4/4 to 6/8 tempo if you just stay at x1 tempo, cut your pattern length to 12 again and use the right accents for 6/8 1-x-(2)-x-(3)-x-4-x-(5)-x-(6)-x, right?
12/16 @ x3/4 Tempo: 3 trigs are the equivalent of three triplets over one beat (1/4)
12/16 @ x1 Tempo: 6 trigs are equivalent of 3/8s, aka half a measure of 6/8, where one trig resembles 1/16th
Personally I have the feeling you can get a lot of unusual time signatures out of the OT. It’s just a bit complicated if you’re new to it, and don’t see how the multipliers and pattern lengths should work together to achieve what you’re after.
