So I hooked up my Casio CTK-4000 via USB, followed all the setup steps, but the "MIDI Track In Indicator" box doesn't even light up when I play -- no communication.

In Preferences > MIDI Sync: "Track" is On for "Input: CASIO USB-MIDI".

The In/Out in the MIDI track should all be right.

Any ideas? Thanks!

bump -- nobody has any idea? Should I contact Casio?

Last try, does anyone have a list of things I should check?
