Google Translate suggests:
I just bought the QU 24 is already provided with a lot of effects , I wanted to know if it was possible to add , and whether autotune effects styles / pitch exist?
At which point:
User effects aren’t a feature – and autotune isn’t on there either.
You could request autotune on the feature suggestions board.
Which Google Translates as:
effets de l’utilisateur ne sont pas une caractéristique – et autotune est pas là non plus.
Vous pourriez demander autotune sur la carte longs suggestions .
