In a certain, ahem, qompetitor's app, it can auto-set the BPM after recording a loop, and then the app can serve as tempo master ("Set and Follow" mode), so you can record a loop and then start an external rhythm player (drum app, etc) that is tempo sync'd via MIDI. This means you can start a live loop performance without a metronome/click track and still get a synchronized rhythm track later in the performance.
Does GTL have this capability? Thanks
