Some features to manage tempi seem essential, since not all midi seqs can send MTC, but most of them can receive it from ardour. Moreover, havings bars in place even if the tempo of a song changes is something important in my opinion :
3 ideas :
1- set tempo using your eyes : by moving the bars to the right place using what you “see” on the envelope of the sound.
2- set tempo according to what you hear : “tempo tap-in” using midi input or a conventionnal keyboard.
3- a graphical editor with a tempo/time graph editable by mouse. much like the master track you have in Muse to edit the tempi of your song.
A feature request has been posted for this, but since no one seemed to care I thought I could make some advertisement.
The feature request is here : #1224
