hello .... i don't use capital letters ...... ....... another program i've had some success with is HYDROGEN .... it was a linux based program that turned mac os x .......... if ya know open source stuff this is the shiz ...... it is a drum machine that will load up any wav file you have ...... / .... you can also use audacity to create these ......!!!!!!!!!!! ........ so then it also becomes a sampler .......... i only hate it cause it doesn't have a gate mode as a sampler does ..... it only triggers ....... BUT ...... if you like programming, all day, you can do the exact thing i am complaining about ......... then you can import your work into garageband via new audio device ............ also the program has links to free drum kits that i've checked out ..... very decent! ..... here's the link Ardour and Hydrogen Tutorial ........ enjoy ..... also look up hho generator on youtube ........ crazy stuff!
