DP 6 Man. Chapter 49, Pages 623 - 630 WHAT THE @#$%

Can ANYONE please tell me if there's a way to change the project tempo WITHOUT affecting (slowing or speeding) MIDI data in the sequence in question.

Dude, chill. Just lock the track in the Tracks overview. Locks to the SMPTE frames.

Or... there are a few other ways around the issue.

1 (easy)- If the MIDI tracks are set and ready to go, bounce them into audio files and import them into a new sequence at the new tempo.

2 (less easy)- This will take a bit of math on your part but will keep you in the MIDI realm (although your bars in the original MIDI tracks will not correspond to the new measure numbers - duh!) It is also something you can do to all or just some MIDI tracks.

2a: Decide on your new tempo. Note the realtimevalues your MIDI tracks start and end times at the current tempo. Set the new tempo in the conductor track or slider.

Now go to your original MIDI tracks that you want to have playback at the original tempo (they'll be faster or slower now depending on which way you went to the tempo). Select ALL the MIDI data you need to "fix" carefully and precisely setting the start and end time for the selection. Be sure nothing else is selected that you don't want changed!

Go to the Region menu and select "scale time" or you could use "scale tempo" (pages 565-8) and apply the edit to "correct" back to the times you jotted down earlier.

I'd suggest reading the whole damn region section of the manual for that matter. Lots of deep stuff in there. If locked tracks work, then that would be your fastest fix. I've had mixed results with locked tracks but frankly haven't had to use them much in a very long time.

I greatly appreciate the (helpful) feedback.
Sorry about the dual post. I am not used to this medium.
I just have to say that I think it's totally bull@#$% that there is not a better option for this issue. It completely ground a session to a halt and required re recording. Booooo

You know of a program that willchange but not change tempo? Or set separate tempos for each track? That makes no sense. It's not a bug or a missing feature. It is the way music and time work.

[North Coast Sound System]

Lol. I'm not sure if I'm addressing how "music and time work". I will say that D.P. is by far my favorite MIDI editing environment. I will also say that locking the tracks and then moving them all to the right points by hand wasn't even that hard of a fix. But locking tracks is definitely not the section I would ever have thought to look up/google/ask about here; (I'd never used that before to be fair). In this day and age of elastic audio. Doubling our halving the tempo is often a feature of MIDI related software that seems to have no trouble offering this option.

Thanks again to both responders with the working workaround
