I'm always generating little random 16 or 32 note sequences. 99% of them are shit, but a minority are really good, stuff you would never think of writing yourself. Even in something basic like Fruity Loops: the arpeggiator in that has a random setting, so you can let that run in a certain key for ages, and then pick out the bits you like. The creative parts are setting the boundaries, and editing the results into something viable.
Most VST synths/instruments have randomize settings as well.
But at the end of the day, it's about taste. You can knock out any old noodly wank, or you can sit and take your time making all these generated parts into a cohesive whole.
BTW: I think the point I was trying to make by starting this thread was that ideas are still more important than gear and..um...a bad workman always blames his tools...or something along those lines.
