Atm, I've got a megadrive emulator that works great, but I remeber having one a while back where I could stop some diffrent parts of the music playing (eg. I could have the drums palying, but no bass)

Does anyone have this or know where I could get this?

Please dont just give me a website withloads of diffrent ones, I'm looknig for a spefic one where I can fuck around with the diffrent parts of them music

Cheers, Inferno
