I’m looking to record using a Powerbook, Logic Express 6, and a Mackie: Spike. My question is: how much inferior would combo drive with 1.33GHz PowerPC G4 256MB DDR333 SDRAM be compared to a super drive with 1.5GHz PowerPC G4 512MB DDR333 SDRAM? If I get the combo drive I would by cheap RAM and install it myself. Please keep in mind that money is always a hard thing to come by for musicians and the super drive is $500 more. Is there anything else I would need to start recording? I'm looking to record by using both live instruments and midi. I'll probably only need one or two inputs. I'm looking to purchase a decent weighted midi keyboard. Do you have any preferences? Would you recommend something other than Logic? Thanks in advance for your help.
