MIDI questions in GarageBand
I'm new to GB and wanted to know if I absolutely need a MIDI interface to hook up several pieces of MIDI gear. None of my keybds, drum machines have USB ports, strictly MIDI. I'm using the breakout cable on my audio card which has a MIDI I/O and have linked the machines together through the MIDI in and thru ports. My old MOTU Microexpress won't work with the Mac because it doesn't have USB ports either. I know there's an adapter out there somewhere but I don't have one right now.
I want to record the MIDI info as software instruments so that I can edit the performances as necessary. Also, how do sound modules get treated in GarageBand. Is it possible to give each voice a separate MIDI track as a MIDI interface would allow? Thanks for your help.
P.S. My gear is a Yamaha SY55, and Alesis HR-16 drum machine and an Alesis QSR sound module for now.
