Hi Flyer,
Ialso use PADs in this way and here is how I do it.
If all my PM settings are to have the same PAD, I Press and hold the SET button until the PANEL MEMORY MODE page comes up.
Press DISPLAY HOLD.
Make sure EXPAND MODE is highlighted.
Go to PAGE 2, right hand side of FILTER TYPE, scroll to bottom 'PAD BANK' use the button underneath to switch it to 'OFF'
Set up your PMs including the chosen PAD, name and save in usual way.
If my PM settings are to include different PADS, I first switch off the AUTO SETTING button directly under the PERFORMANCE PADS
(lefthand side of keyboard).
I then do the same as above making sure the keyboard is in the EXPAND mode and that the PAD BANK is switched to 'ON' but this time I set individual PMs with the choice of PAD included in the settings, name and save to Bank (if using them).
The reason for saving each PM individually is because if the Music Style Arranger, Music Stylist or Custom Stylist is used, they have their own settings including relevant Pads and therefore when you change to the next PM, you will get whatever Pad was used with that PM which can be very embarrassing when playing 'live' believe me I've been there, and got the'T' shirt, as they say ha! ha!
Hope this helps.
