Loop adjust for not quantize tracks or acappellas

Hi! I have a question, so many songs played or acappellas are not quantized so the loop is not precise, is there a way to adjust L ’IN and OUT to make the loop precise?

Loop size is determined by bpm so you probably have a problem with that, not quantization

certain that the problem is quantization, an acappella or a song played, like 70s songs, they are hardly quantized, so to make the loop you have to create it manually but to do it precisely you should do something like pioneer, which by pressing “IN” or “Out” after creating the loop, you can correct it if it is not accurate … with the old denon dn s 3500 it was possible to do it
