Hi all! My problem is: I have created two iterations inside of one live loop, after that first live loop, I created another live loop and I synced it to the first live loop. The second one is a beat loop and is not being played within the sleep value that I attributed to it:
Hello @ekepan 
There are in fact several ways to sync live loops together: either by syncing once when a loop starts, (and having the synced loop operate independently thereafter), or syncing every time a loop hits the sync command. This second case is what you are observing here.
The various uses and behaviours of live loop syncing have been discussed at length in several prior threads - See my comment here for further details:
