hey lordy, i have the same problem too. is like at the start of a song, you haven't started even struming yet, then suddenly the guitar will start 'strumming' for you until u get booed off stage. for me, i solve that by never touching the touch pads. the problem only starts when start to touch it and will continue randomly after that. so no touch policy kind of works for me.

btw, what is the rubber band IINM fix? kindly elaborate

If using LCD TV, lag problems are more prominent. But for me is not due to lag (done that, been there). glad you resolve your problem already. I can imagine the frustration if u haven't. anyway, i don't really miss the touch pad so much. u can still play pretty well without it. The more important skill to master how to alternate strum (2 way strumming). for some hard/expert songs u will need it.

solution as above discussion. it could be due to lag, or geniune problem like mine which i just ignore.
