I opened a song file in studio one 5.0. I added an instrument track to test out EZ BASS. When I played the original track back, the pitch was higher than the audio recording. I deleted the EZ Bass track hoping it would revert back to the correct pitch. It did not. I closed the file and did not save the updated steps. I reopened the file and it still plays higher than the vocals and acoustic guitar I recorded. Can someone please help me understand what may have happened and how I can get my tracks back to the correct pitch? They were good recordings and I am really worried that they are ruined and not understanding why it happened means that it will most likely happen again. I am using a Mac book pro if that info helps at all.
Also, I made no adjustments to any sample rate or anything. Literally just did the steps listed above. Thank you for any help
