hi,

you cannot set a tempo map via MIDI Clock, sorry.

you can only set the current tempo of the qtractor timeline; also, tempo maps of different applications (Ardour vs qtractor) are not exactly shareable or set with MIDI Clock, not even with with JACK transport/timebase: the master, the one sending tempo information, often overrides the slaved (the receiving one).

moreover, the ardour tempo map maybe very loose or continuous with varying tempo across the timeline, while in qtractor tempo changes are discrete and strict to bar/measure locations.

all that to say in conclusion, there's no way to convert one tempo map (ardour) into another (qtractor), at least automatically via MIDI Clock or JACK timebase; the opposite (qtractor to ardour) might be possible tho idk.

cheers
