Hello, I have a PX5 and have a few questions. Please note, that I use AP on my gigs, and am starting to use the PX5 on certain situations, so excuse my lack of knowledge and procedure with this machine. First, I got this awhile ago, I have only updated the firmware once, so I think its at V 1.2 or something, its not in front of me. I want to load new sounds, like the new eoads mark amp. What version firmware do I need to bump up to to load .zpf files? Why is the ALL File a .ZAL file? And can I load this with the firmware version Im at?? Im thinking I should update the firmware version to the present V1.13 ??, then do the ALL FILE if the sounds r that much better, then add the roads mark amp???? Im looking for instruction on how to properly do these things, and the order in which I should do them, so I would greatly appt any help and guidance I can get here. Thank you, greatly appt for your time and help. A.
