Renoise & M-audio 410 Fw

Hi 2 all renoise crew!!

Well,I need help!. I´m starting to producing with renoise and I´ve got an M-audio 410 firewire card connected to my g4 700 emac with 1gb ram & all soundz & samples in a lacie external 160GB HD firewire too. I know my cpu isn´t the best talking about speed, but working on the renoise demo for mac, the sound crackle & isn´t the best sound i want. Without the 410 FW it sounds with a better latency. I think on mac there´s no ASIO support, only Core Audio. The question is if that situation would change if i work with a registered copy of renoise or not. Somebody can help me?!!! ;)
