PLZ FIX THE VOCAL TRANSFORMER

Hey Apple, I LOVE GARAGEBAND! I use it almost everyday and its super pro for its price BUT I have one major issue, the vocal transformer effect. (The voice pitcher etc.) everytime I try to use it my voice becomes really choppy and delayed from the mic idk why and its rlly annoying because I really need to use that effect and its pretty much useless because you cant record anything while using it with the delay and the choppiness :( . PLZ FIX THIS, IM BEGGING YOU I LOVE THIS APP!!!??????
