The biggest issue is just timing. If you are good on any instrument you should have that under control. So you are at least ahead of the game. But you gotta play it right. Yeh, you could just urinate all over the Muses and sit there and chop it up in the computer and place everything. But, if you want to be a data processor, do it for someone else and at least get paid for it. The music world don't need anymore of that.
