yeah man if you're gonna have a hardware setup like that, you better use the fuck out of it. I would kill to have all of that shit
Get sick drumloops going, manually shift them throughout. You should never have extended moments of silence (or near silence) in your "set" when you have all of that equipment!! You could have a rad beat going during load times between lsdj saves, and then bring whatever melody (or whatever it is you're using the gameboy for) in on top of the drums... do it perfectly in time (use headphones) and fade it in using your effects processor
Basically, you have all the awesome shit that most of us wish we did.. now you just need to practice a shit ton and get creative with it. Would be cool if it were a bit more on the dancey side as well, but that's only my opinion
