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:

> Hello @hyphz! You’re in luck, there are some detailed discussions about this issue wink - One of the best ways I think of avoiding the undesired delay is to use the sync: opt of live\_loop. Ie: live\_loop :bar, sync: :a do ... That way, your loop will sync before it’s about to start, and from then on, just plays without syncing further. There is a small gotcha though: it will only sync on cues after they have happened - so while the two loops would be in time, it would effectively wait for…
