Hi, I just purchased a Pa500 and I' m using it with MOTU DP4. I have a really hard time figuring out how to insert Bank select + patch # . With the is4 I had a choice of 2 contr. #( ex 56 + 0 + prg# for GM sounds or 0 +1,2,3 +pgr# . (MSB vs LSB) Can somebody help me or tell me how to download pa500 total banks and patch list ? Thank you
