How to change tempo without affecting the music (only the grid)

Check out Region>Lock SMPTE Position.

Key Command +Automation Event List+.

*Logic Pro>Preferences>Automation*
Set *Move Automation with Region* to Never or Ask.

Set Move Automation with Region to Never or Ask.

I can't confirm this to prevent Automation from slipping with the changed Tempo.

When you're in the automation event list, you can select all and lock to SMPTE, just like in any other event list window . .

TY Malcom. Good tip!

This is not as efficient - you can move the track automation data to the region -

Track / Track Automation / Move all track automation to region

There is also an automation arrange page level, i.e. you see the automation as objects on the arrange page. It's really difficult to find - this is Logic, after all.

here's how i do it - after checking on your arrange page that you have the link box checked, go to the aforementioned automation event list, then click the crooked arrow "one level up" button at top left of the event list. This should take you to what looks like an arrange page, but with just the automation data in folders - incredibly useful, incredibly undocumented 9 at least up to L9 - maybe not so these days . . )

anyway, i mention this, because you can also lock these automaion folders to SMPTE, which might be slicker

You're close!

1• Open the automation event list on a track that contains automation. You will now see what looks like a normal event list but it's displaying only the automation data on that track

2• Click the hierarchy arrow to take you "up a level" so that the automation event list (AEL) now shows you the names of all of the automation regions within the (hidden) automation arrange page. What you'll see is a list of items all starting at bar 1 1 1 1 called "Automation". (If the position of the items is not 1 1 1 1, you have a problem. See below).

3• Select All (CMD-A) and then use whatever method you prefer to SMPTE-lock them (menu item or key command)

= OR =

Do Step #1. Then hit CMD-1 to open a new Arrange window. When you do this right after opening an AEL you will see the automation arrange page. Move the AEL out of the way or simply close it. Then, similar to Step #3, select all of the automation regions in the automation arrange page (CMD-A) and SMPTE-lock them.

Note: if your automation events are not all starting at 1 1 1 1 then it's an indication that your song's start marker was moved to before bar 1 and you're on your way to having a corrupted song.

Final caveat: don't attempt to write new automation while the old automation data is SMPTE-locked. It'll create a nice lil' mess. So after you're done changing the tempo (or whatever your reason for SMPTE-locking regions and automation), the first thing you should do is unlock them both before proceeding with any additional recordings. It's very easy to forget that the automation data is locked because you can't see that it's in a locked state unless you're looking at the AEL or the automation arrange page.

yes! Malcolm and iShwartz, I saw that trick with the Automation Arrange page on a macprovideo tnt tutorial before. Did you see it it too?

It's great to have it available. Though the Original Poster started off the thread with "This is a very basic problem." I read that to mean he wanted a simple solution. As great as the Automation Arrange function is it ain't the simplest of methods. Then again there's more than one way to skin a cat in Logic and the good people on these forums help provide all the different methods to do so!

And when you're done with jumping through all these hoops, you'll spell a vow to not start without a properly set Tempo ever again.

Hi JG99,

No, I never saw that video. First time I saw mention of this was during a discussion over at LPH about two years ago (or more) with respect to resyncing music when scoring on Logic 7. Locking automation events has become a regular part of my workflow ever since. Though honestly, in contrast to what the OP said, it's not a simple problem at all. It's a pretty complex one, but fortunately the solution is very simple, and takes only 4 key commands to accomplish 🙂 as follows:

• open automation event list (mine is CMD-E)
• open arrange window (CMD-1)
• select ALL (CMD-A)
• SMPTE-Lock (mine is CMD-L)

Then close window 2x (mine is ESC)

Make your changes. Then reverse the procedure, this time using unlock-SMPTE (mine is CMD-U).

So in terms of keystrokes for locking or unlocking, hold down CMD and go bink, bink, bink, bink. Then let go of CMD and bink-bink on ESC to get back to my previous view. 😉

Thanks iSchwartz,

You're completely correct. It's not a simple problem. I think smpte locking automation is genius.

You must have set up your key commands different to me. I don't have a 'bink' key on my keyboard. 😉

LOLOLOLOL! I'm reading this just as I'm out the door to having a meeting with my attorney and your post put me in a much better mood. Thanks! 🙂

Oh, and BTW I'm pleading not guilty to all the charges, include modifying my key commands without a proper permit, trespassing on undocumented features, creating a nuisance (well, I'm not totally innocent of that one) and writing cues without first establishing a tempo. Well, OK, I'm kinda guilty of that too but, see, it wasn't my fault. The director re-edited the film and...

"Yes, that's right your honor, the butler did it!"

LOL. You're definitely guilty of one thing - posting awesome solutions for Logic issues on these forums. Of course that's true of many of the regulars here - hopefully myself included.

Point the judge to this thread if you need a character reference! 😉
