got a performance tomorrow night need help please!!

[tannedbythemoon]

Help please help!!! I rap and make beats and I want to perform with my sp404sx playing my beats as long samples and putting effects on my voice going through the exit source.
Is it possible to set the tempo of the delay I put on my voice to be the same as that of the samples beat?? possibly by using tap tempo? I've been stressing tying to find out but have had no luck, any help would be very much appreciated! Cheers

On 555 it's effect assign + tap tempo, I guess it's also something like that on 404sx.

literally just turn the left nob until its somewhere near the middle, thats usually the best spot to match up with 80-90 bpm, you just gotta experiment and practice and youll get the hang of it
