mu128 / mu100 plg bank access ?

just curious if anyone here owns either unit with PLG's installed...I have a 128, do you have to assign the bank numbers on the unit itself for the slots or can't I just access them like before by a simple bank number ?

I have 2 cards a plg-an1x (in slot 1) and the plg-pf (in slot 2)

I have seen instrument def's here for sonar somewhere.. but previously when I was using the an1 in my sw1000xg card.. I could just put the bank in as 4608 / 4609 and it'd access the an1x.. I can get the normal XG playing, but neither of the plg's given the bank 36..

also I'm getting a midi buffer overflow on the unit, using both midi in's / outs.. on the 2nd 

cheers..
