mac laptop set-up

[Jeff Blanding <jeff@modaldub.net>]

hello,

i am thinking of getting an Apple iBook for live use as an instrument 
(softsynth, sampler, looper/fx). i would like to focus as much as 
possible on the iBook and have no external gear, since i am thinking of 
traveling a lot with it. has anyone on the list done looping or live 
electronic music with their mac laptop? what was the set-up, and do you 
have any tips or feedback from the experience? i have lots of questions 
about various things, such as how to route the signal internally and be 
able to go through various effects, use different apps at once (VST 
instruments, etc.), and mix it all into a pair of stereo outs. i've been 
playing with apps like Absynth, ReCycle, Phrazer, Cubase/Logic/ProTools, 
Reaktor, Koblo, various VST instruments and effects... i basically want 
to be able to route whatever sampler or softsynth i am playing through 
effects and also do some triggering and sequencing among the different 
apps. i mostly do live improv so i prefer triggering different samples 
manually to sequencing the whole thing, but i would be curious about 
sequencing also.

anwyay, any relevant advice will be appreciated.

thanks,
jeff
