Hi, thanks; isn't it strange to have it there and not in the Transport
tab in Preferences, where all the other sync options are?


Last night after lot of cursing I finally did manage to do what I was
after, with Ardour and klick. The two things I was doing wrong were
having Ardour set as Jack Master (because I was looking for that option
in the Preferences) and not understanding how klick works. Basically,
if you have a tempo map file like this

firstpart: 	10 120
secondpart: 	2 120
		4 120-135
lastpart: 10 135

you just have to run "klick -T -f tempo_map_file" and, whenever in
hydrogen (for example) you'll move the playhead to measure 13, it will
start ramping up the tempo to 135 in 4 measures. My misunderstanding
was that it would start counting measures from the moment you executed
the klick command, instead like this of course it's much better, you
can even put that command in your non-session and forget about it 

thanks to all that helped me :=)
