Hi,
Thanks for the suggestions,
Shift&click Ctrl&click Alt&click all have no effect
Piano and guitar window both work which at least gives me a work round, thanks for that, but it doubles the input for adding a note.
1-peg hot key works
Delete function works can also move existing notes about using the mouse.
I have unplugged both the keyboard and the mouse and put them in different usb ports with no effect.
I am only running Real band on its own.
Many thanks for your help so far , there is obviously something happened between my computer and Realband but at least I now have a way forward,
Regards
John
