Thanks Gary - I should have looked here first but I very naively thought that the Yamaha sites would have this info.

I kind of panicked as I have now got used to using just the Tyros now that there is a "fudge" to display lyrics which are not part of a Karoeke file.

I will probably be getting a Tyros 2 so I will no doubt be experiencing a few of it's teething problems......

Incidently, there are hard factory reset instructions for all other Yamaha keyboards and clavinovas on their site - it's just not up to date. Most of these need B1 or F0 being held down during power up although the PSR9000 is an exception and uses the demo button. However it is safer to use the test procedure as the last page of these gives the option to do a reset.

Thanks again all

Keith
