Your absolutely spot on, i'd build it with a fixed number of tracks though..... you'll hit speed barriers when you move above 8 anyway, and trying to set 8 at once is a challenge, remember you have to listen for the playing position for all the playing tracks first so your in danger of creating a cpu hog....

Hi S4racen, thanx for the comment, i think i'd like in principle to change just loop start/stop and loop on/off properties, but i'd like to have it general, meaning adapt to an unknown number of clips. Would you do it in a group or just with clips in different tracks in the same scene? A

Changing Loop Start End Point needs looping to be set on otherwise you change the actual clip start and end point, pay careful attention to the order in which you call your actions...

I....

Call Loop On Set Start Set End Deferlow Call Loop On

I have a Live.object that is pointed at the playing clip in a track, to have one object that iterates between all the playing clips will simply not work in the time scale that youre aiming for, hence my suggestion to work with a fixed number of tracks and observe each track seperately for it's playing clip, it's playing position and do some maths from this number to calculate the loop start and end points you want to set....

Cheers D

ok that's why i was getting all these weird behaviors in the start and loop points.. well now i use a poly~ with istances defined by the number of clips, and will test with one clip extra to see how it goes.. in case i encounter some problems i'll report back.. Thanks a lot D A
