I've been working on a nano replicator compiler for a while, but can't remember where I misplaced it.

My understanding is that M80s sound like big M22s, and M22s sound like small M80s, and M60s sound like bigger M22s, but smaller M80s, and M2s sound smaller yet, although are almost as loud as M22s just not as big, and Rockets don't sound like any of them at all, although they sound good, but warm.
