Cubase 9 Pan Problem

I loaded up a project this morning and found the both my Halion 5 and Sonic 2 sounds where all panned to the left-has anyone else had the same problem?

You using track or rack instruments?

Check the midi track if its a rack instrument.

using rack instrument

You might have to re center the pan on the midi track then

Many thanks ifvit happens again I’ll check that out
