Hi Jeff,
Thanks for that. I've observed that most editors in this PD class do similar things, but call them by diferent terms and the 'how to' varies wildly. So it was a matter of getting what PD does in rippling all the tracks sorted . .
I'd tried move clips, but that left a text item out of sync.
Also tried lock tracks, thinkng this was a way to keep them in sync, but all that did was prevent any further editing on any track. Frustrated, I took to RFM, and the manual agreed, but clarified. I can't think of a reason why a track lock as has been implemented would be necessary; by that stage, the project is finsihed and rendered??? but who knows . . .
Move all tracks on that insertion menu looks to be the one that does work.
