Create sample on WaveLab genre acapella

Hello to all

I’m on WaveLab 8 studio and I would like to create samples recover on a reggae music eg but trying to keep that voice or almost and I get lost a bit in all the filters so if someone had an idea in order to mitigate the bass and other so Recover almost only the voice >

Thank you

It’s not quite clear what you want to do; remove music and keep the vocal of a mixed track?
