i know theres got to be a way maybe with autotune but i dont know how to use it.

im usin acid pro 6 so if anyone know how to fix up the quality let me know

[quote quote="TheFOA":2nvqsgld]Sounds to me as if your instrumental and your original song werent the same quality… That will happen. That is actually a good test to show you the difference between to formats quality wise.

OR

You may not have lined up the intrumental and The original song perfectly… So you may be hearing remnants of waves from them not being perfectly aligned when you nullified the instrumental by reversing the polarity.

So try to begin with the best quality/works possible. And you can play with the eq to fix that more than likely.

But it sounds to me as if youve used maybe a wav and an mp3 or 2 mp3s with different bitrates.[/quote:2nvqsgld]

i didnt use any beat to make this cus there is not beat to dat song i do pellas a diffrent way but they all come out this way now i know theres gotta be a plugin out there that can fix the quality up just a little
