If the external source supports syncing to MIDI clock (Bug #682221), Ableton Link (Bug #1625050), or JACK transport (Bug #1130864), it would be better to use those instead of trying to detect the BPM of a live input. Nevertheless, detecting the BPM of live inputs would be helpful when none of those syncing protocols are supported.
