That, and have the actuator on the strum-bar strum both up and down.
The more difficult songs you pretty much have to strum both ways to do well (especially during the solos)

Its an obvious fix. Hydraulic actuators. For example, intake/exhaust valves in the new F1 engines can do 18000 RPM, solely because hydraulics are used instead of the usual cam / cam-rocker system.

If it predicted when the key needed to be depressed, it could probably be fast enough by starting the pneumatic actuator early (unless it’s the strum bar that’s slow). The click just needs to be registered after the strum. If it is the strum bar that is slow, most of the fast sections are hammer-on/pull-off which do not require strumming. Taking advantage of that would probably require a better “note” identification scheme.

Also, from my experience with GH, button depression is slightly slower than release, it might help to keep keys depressed (on single notes, lower fret buttons override higher ones)

Kinda funny that it can’t quite hit 100%. I guess humans are still faster than labview :P

still pretty cool though. I wonder how they could speed it up.

At this year’s “Vision 2008″ fair (in Germany) I was presenting the robocup system of our university in the same booth as the cythbot so I had the chance to watch the system live. It was a really cool hack, but after three days of standing next to it, I had problems getting “Cliffs of Dover” out of my head ;-)
