If you have a folder named Kenneth in ~/Movies/Motion Templates/Transitions, then delete the 5 band and 5 band mask folders and copy in the new versions attached in this post.
If you don't have a folder named Kenneth, extract the attached file in ~/Movies/Motion Templates/Transitions
Is it possible to have different speed on each band when using Seq.Rep?
diff. speed for each band - no.
For sure, you can adjust the 'spread' of the bars, but that is 'global' for all. Setting a diff. Traversal gives slightly individual speeds, example when you ease-out the movement, the last bar comes a lil later than the others...
Generally spoken: replicators and esp. the Sequencer are meant by concept to … ehm, replicate=multiply by copy one.
If you want to control each bar individually, your concept of individual masks is superior. You could link all 5 bars to one 'custom' behaviour, to allow sequential action AND individual one.... don't forget: you can 'record' keyframes for rigs! A very powerful feature in M5...
have a look at my tut, around 2:30 ... ok, key framing the cam, but works with any other keyframable parameter too.
