Could just do drum rolls, honestly. Though that would come out sounding quite different musically from a guitar sustain, it's pretty similar from a game design standpoint.
As a piano player, my instincts tell me that you should have to hold down the kick pedal for sustain. For those that don't play piano, when you hold a key and hit the sustain pedal, the note will continue to play until you let up on the pedal or it decays a natural death.
Of course, I don't think the devs want you to use peripherals to control this game at all. The whole point is that you don't use a plastic axe to play it.
Once again though, I'm not expecting to use instruments for Blitz, so not suggesting this fix in that spirit. More as a fan of puzzles that likes to find solutions.
Wanted: Ayreon, Star One, Guilt Machine, Ambeon, Road to Consciousness, Ten, Frost*, Clive Nolan & Oliver Wakeman, Rush, Them Crooked Vultures.
We can't use instruments, but won't the face buttons on the drums technically work? I mean, hell, I can get a drumkit to do things in Halo 3, I'm sure the face buttons count for Blitz.
Not that that's really useful or practical, but still.

Why would you want to set up a drum set, mic, and mic stand when you can just use a regular controller?
