The Logic Off Topic list

All,

Hello, I've heard good things about this group and I'm sure you'll 
be able to offer me some advice with my problems. Please treat me as 
beginner. My set-up is currently as follows...

Apple G4 running Logic
Tascam US-122
Alesis M1s
Yamaha SY22

Please could you help advise me on how I hook up my Alesis M1s to my 
Mac, do I need to buy a mixer or is there another way? Could you 
advise a cheap, quality option?

I'd be really grateful of some help,

Many thanks, Phil.
