problems playing 3.3 on 4.1?

anyone else

I use a pen 3 to do portable recording. I can get 8 tracks using 3.3 and my Layla.
I want to use 4.1 on a Pen 4 to do the mixing, but the importing is messing up somewhere.
Anyone else having trouble using 3.3 sng files with 4.1 program?

What exactly goes wrong?

Is it something to do with the changes to the Aux send/recieve settings (pre/post etc)?


Importing 3.3 to V4 is a real pain.
I came to the conclusion that I would wait until all my projects started in 3.3 were finished before I would upgrade.
