Tony, I'll second your comments on the KN7 against the Tyros3. The KN7 is still the 'tops' for me.

I have always used the panel memories as I play mainly for dancing and singalongs and because of this I tend to set up medleys of 3/4 tunes set to the same rhythm but using the variations and pads.

By pressing and holding down the blue button in the middle of the PM wheel, you will be taken to the 'Expand Mode Filter' (2 pages)
On page 2, there are different options and one of them is to have the Pads in the 'on' or 'off' mode, so when I am setting up my song/tunes I include whichever Pad option I need, plus anything else that is relevant i.e: R1/R2 octave ON/OFF.

Finally, my 2 or 3 songs/tunes are saved together with their particular variations into the panel memories. (Job done and saved all in one go, no messing about like the T3 setups)

For example: I have a Country Medley in Bank 'A' named "ACT NATURALLY - MED"
PM 1-3 holds the sets for 'Act Naturally'.
PM 4-6 holds the sets for 'All I Ever Need Is you'
PM 7 - 8 holds the sets for 'Oh Lonesome Me'

all are played to the same rhythm but with individual variations, pads, voices, transpose and octave changes, which keeps it interesting (I hope ha! ha!)
