In 2005 I made a MIDI drum machine program[1] that could accept ASCII drum tablature as input to varying degrees of success, either by loading from a file, or you could just paste it in with the mouse (either via middle mouse button[2], or right mouse + PASTE). At the time, mxtabs.net[3] had tons of ASCII drum tab, but it shut down a short time later (2006).

My program could try to re-factor these drum tabs to pull out common repeated patterns to be represented in my program's native format. It was a fun project. (I'm a much better C programmer now than I was then.)
