hey, there is something in those app settings a protocol called "ableton link" or sometime's just "link". I think all those app have it, at least ispark does for sure. turn it on with all those apps, should sync up to tempo automatically. it's really easy to use and no, you don't have to be an ableton person to use it. there is also an app called aum which i recommend to anyone using multiple music apps at once
, makes your life easier with syncing and any midi you want to send
