Help..importing Midi Creating Timing Errors, Turn off midi snap etc in a song. Options

[PAUL R]

Here goes.....
I have a mix of a song created in a commercial studio - I bounced a rough stereo mix and imported the stereo mix into a new project at home so that I can add keyboards.
I set project tempo to 165 BPM
I got my talented friend to play keyboards via midi to the audio song at home and all is great.
Perfectly in time.
Then burned off disc at home containing midi data and audio file in sync.

Then I took the project back to the commercial studio and imported the midi keyboard into the original song.
OH SHIT - the original song was 163 BPM not 165 - I made a mistake but now the midi keyboard part is out of sync.

Have tried moving the midi part but it will not go back in time.
Yes , I can bounce the midi keyboard part to audio and import this into the commercial project but I lose the ability to edit midi or change the keyboard sound in the final mix.

I use Logic latest version and the commercial studio uses Logic latest version too.

Is there a way of turning the midi 'snap' or whatever that makes the midi think it is playing at 163 ??

In other words can I import the midi as I would audio that does not take into account the 2 BPM difference ?
Does the midi have to stick to the songs tempo in which it was recorded ?
It was intime with the audio at home..
Surely there must be a fix....
HELP !!
