Wanted to do some triplets yesterday, and it was harder than i thought, i usually have my pyramid in polymeters. and i noticed that i could not use the methods described here, which makes sense, when thinking about it.
But i found another solution, “Repeat smartpads” in live mode have triplets, and their start point is always quantized, so i just punch in my triplets where i want them. works great, and if you want slower the 1/8 triplets, just change the TS to 4/2 or 4/1 to half the speed of the repeater.
I guess offsetting by 0% 33% and 66% would also work, but this is so much faster.
