Hi, you need a sequencer that records a tempo map following you tapping a key. This automatically would set the tempo, BPM in relation to the time code position. This works very well to sync a sequencer to "averaged normal music" played by real musicians. After or before doing this you still need to manually edit the signature. No software is able to detect if you are playing 3/4 followed by 2/4 or if you are playing 5/4. Apart from this, if you are really playing by pulse, recording a tempo map might be more or less impossible, since when you actually wouldn't count, you need to count, resp. tap, so that the sequencer knows at what tempo you are, where quasi no tempo exists. In short, a feature to sync a MIDI sequencer to human played audio tracks by tapping a key does exist since decades, even to analog audio tapes where the sequencer is synced by SMPTE. I guess you won't find this feature provided by Qtractor. There only seems to be View > Tempo Map > Tap to set a tempo at a given position, not to generate a tempo map while playing the song. Maybe Ardour, Rosegarden or another Linux sequencer provides it. I suspect that assuming Ardour's Rhythm Ferret should still exist and assuming it should work, it just would work for "averaged normal music", https://community.ardour.org/a3_features_ferret . However, beat detection is for sure less good than tapping, if you are playing by pulse. Sync is an issue for all computer platforms, but Linux for sure is by far the weakest platform in this domain.
