New member, apologies if this is an old topic.
I've been using a Roland XP-50 since 1997, and have bought the Classical expansion card and just this month the Keyboards of the '60's and 70's card. I can't figure out how to use controllers 1 and 2 to work the Rotary EFX, and I know they did this on the "Expansion" demo CD. What do I do? I was almost ready to buy a Roland RT-20 pedal, but they're $150+ USD and why, if I don't need it? This is a terrific expansion card; I'm really happy about it.
Thanks in advance for the expert advice!
