Thanks. I think first of all I should update the OS and resources from Korg website.

I also want to know if the sustain pedal does what the joystick does or not.

According to this video: http://www.youtube.com/watch?v=XJZc8XI2uxk it looks it can only make a tap sound.

Also, can I connect Guitar stuff, like amplifier and processor (Digitech RP350 which has a pedal) to PA500?
