Hi ,
For any pa4x owners who may not be aware
If you come across any original old pa1x , pa800 styles etc
and they only have the original 2 fills instead of 4.
A simple way of fixing it is
Choose style( even appears to work in direct mode)
Hit Record Button
Choose record/edit Current Style

Pop up
Fills and guitar mode have been converted

Press ok


Drop down menu
Write style
Ok saves it.
Press record button again
Press Yes to the pop up( you 've already saved it)

You now fave 4 fills instead of 2
And any guitar mode 1 tracks have been converted to guitar mode 2.
