Shifting timing between a midi track and its duplicate track

[Rod24953]

Hello there

I'm relatively new to Logic Pro X and I wonder if anyone can help. I'd like to record a sort repetitive sequence of notes and then produce a duplicate track of it, which when both tracks are playing drifts slowly out of sync but then drifts back into sync after several sequences. A little like 'Rounds' in childrens' songs.

The effect I'm after is like Steve Reich's - ' Music for 18 musicians' or 'Clapping music' where the musical phrases tempo (or Clapping) drift slowly out of phase and then drift back to lock in.

Any advice or tips would be greatly appreciated.

Best wishes

First, establish the spots where both sequences are in sync, yet one, two, three etc. 8th notes apart.

Then define the length of transitions, say four bars of 8th, that's 32 notes.

Create a Region of 33 notes on the second (drifting) track. It should end right where note 34 would start.

Then option-grab the lower right corner of that Region and drag it left so that it falls right on the downbeat, where note 33 fell before.

Here your new time interval locks in and track two is one 8th ahead of track one.

Hello Christian

Many thanks for your very prompt and well spelled out reply. In hindsight, it seems such an obvious solution, although it clearly wasn't to me.

I'll give it a try tonight and thanks again for your help.
