Logic Pro 9 how do I make MIDI stand still while changing song tempo?

[peterlemer]

My son has transcribed a jazz piece for me on GB, and once imported into L9 it more or less plays MIDI in synch with the original MP3.

However, I want to click up the audio - I'm getting good at that 🙂

but if I put in tempo changes it will take the MIDI out of sync.

How can I 'freeze' the MIDI in it's present incarnation while changing the song tempo?

Lock smpte position before introducing the tempo changes?

Either Eli's suggestion or use the protect MIDI check box in the beat mapping global track.

Never hurts to make a backup copy before you start such in case you made a nasty error in your method.

brilliant, thanks Eli 🙂

Doug, the beat mapping thing is new to me - I think it will come in very useful in other projects, thanks too
