Fruity is bar far the best and easiest to do, unless you are skilled with Adobe Audition, then that's pretty easy.
Sony Acid Pru 6, my best friend uses it for his solo project now i have tons of beats in you need em or plan to use Acid. If you wanna check out his solo project go to myspace.cm ( http://www.myspace.com/syntheticsins )
Well frooty is the easiest but as people already said Audition is far the best. Its not that hard after you find some decent samples and get a tutorial on how to use it (beginniners guide or something) I know how to basic use audition but its nothing to scream about Theres also Dance Ejay and Ejay 360 which are really simple to use but are not very good
sorry to go off topic, but with any of those above programs, is it possible to construct techno music?
