First of all I am not audio professional, I have recorded some stuff and somehow managed to get everything working in Windows environment, but now I would like to make use of my PowerBook, just for fun. I have guitar, bass and electric drums + 2 very cheap microphones. I borrowed this Roland UM-1 box thing from my friend and this thing allows me to connect my drums to my external soundcard which Soundblaster Extigy, probably not the best thing around but I just happen to have it. It uses USB and I have been told that especially for machines this old FireWire is highly recommened. I am not 100% sure if Extigy is compatible with Leopard but I think so, I have find its AC adapter which is here somewhere And now the main question, what software to use? In Windows I have used Cakewalk Sonar and it has worked fine with multiple effects and stuff, I actually didn't even use guitar amp but Guitar Rig and in real time, drums were made with Ezdrummer so I only had guitar and computer, now it's different. With PowerBook my plan is to not use heavy software audio effects, but I need to get MIDI recorded and this is actually new thing to me, I have never recorded by using MIDI, only audio so I'm pretty sure there is lots of stuff which I don't understand. Any tips? PowerBook would be nice because of its size, I currently don't have instruments arranged reasonable way because of space constraints so I could just move the laptop when needed. EDIT: Hmm, looks bad for Extigy: https://discussions.apple.com/message/9466641#9466641 I could of course downgrade even to Tiger if I absolutely needed.
