found it. its in Future Music mag. a very helpful source
now that i looked it over, for your situation, i think i would competely reccomend
Ableton Live 5
they quote it as "straddling the line between instant gratification and professional performance,
live 5 fuses the intuitive real-time looping features of Acid and GarageBand wit the flex and depth of pro sequuencers like Cubase and Logic."
They compared it with Apple Logic Pro, which i would say is a large compliment for
Live 5.
Live runs around $500, and the article highly reccomends it for your uses.
goodluck with that
