Q: play wacca with touchscreen?

[laflegge]

What is a better way to play wacca with a touchscreen? To be precise : I use toucca now but feel it is all a bit to fiddly. The band where you need to touch is very small and more then often you are just a few millimeter off and therefor missing a note.

So is there a better solution?

(ok: the best way is of course playing on the cab)
