I have played guitar for a while and am just starting into electronic music. I want to take a single sound sample and create a instrument with that sample at each note(c,d,e,f,g,a,b etc.) on my keyboard. Any suggestions on which software I should use. I just switched to Mac OSX and have a 2.8 ghz power mac with 512 mb ram. I am using garage band for right now but will be switching to logic when I have the money.
