Hi Funs and thanks a lot for the message! Sorry if I'm launching noob questions at you, but so far I've only used a tabplay~ object and a metro with a set bpm, and triggered both of them at the same time- this is obviously not ideal..although it "almost" works the fade into and out of the drum loop should be perfectly timed, especially for this kind of application.I am, however, a little lost as to how extrapolate bar/beat information from the objects you suggested. I'm sure it's super easy and I'm missing something obvious. Why do you put the 1000 in the message that goes to the line object?
