I sometimes have detuned beats, usually by -50semitones, I use bx_crispytuner as that's what I can afford, but I guess what is the best way to go about this, just keep pitching all my vocals -50 semitones to match it? though I heard that creates artifacts.

does anyone also know if there is some setting in here to make it more accurate for that? yea, a little lost on the cleanest approach here, but I feel a lot more emotion detuning it sometimes

 

If you sing to the track after it's detuned, then tune it (to the lowered reference, obviously) you shouldn't get artifacts. Or at least, no more than normal for tuning.

 

you hear infrasounds?

 

Might be -50 cents? American usd? Euro? Semitones is too much....

 

Even if 50 cent is not a problem for vocals, it's not as easy as pitching a beat which is really easy and your DAW (which?) should be able to do this without any 3rd party plugin.
