Project suddenly two semitones higher

[TrevsAudio]

Hey guys!
Like it says, been working on this for a couple of weeks, then today I suddenly sound like Mickey Mouse! Everything had somehow transposed 2 semitones higher. I had to go into the sound tab for each clip and lower them.
They are all audio files.
Any idea what might have happened?

EDIT: GOOD GRIEF! Went straight back to the project and it had corrected itself! Now have to shift all the clips back up again

Any particular third party vst acting up?

Trev, you back on the Helium again?



Besides what Tom mentioned and the parameters on the Sound Tab, the only thing I can think of would be something in the automation lane or another effect with a pitch adjustment on it.

Thanks guys.. Nope Tom - all stock plugins - keeping it simple this time around
Helium? Now there's a thought!
Yeah, all good again today - must have been some mischievous gremlins in the studio...

Ah Ha! Mark has it!
Just realized I switched from my Focusrite 2i2 at 41K back to my 18i8 at 48K

Thanks Mark
