I recently rebuilt my PC and the in the process upgraded to Cubase 10, just getting the opportunity recently to dive back in to some recording. I set up an intrument track (using The Grand 3) and it plays a semitone down. First I though it was a midi send issue from my keyboard, but if I play on the the little keyboard thingo in the VST - it’s flat!
I checked the setting of The Grand and it says it 's set to 440Hz, but it definitely isn’t. Got me dumbfounded! I checked the same on Halion Sonic and it’s the same. Doesn’t matter if its a midi instrument, or a rack instrument.
Could it be sample rate issue? I dunno why ti could be that, but thought crossed my mind. There is a possiblilty I don’t have the same driver for my audio interface, but I can’t see how that could affect anything.
