I tried opening both a .SEQ and a .SGU file and there was no indication on the Input VU's of any activity.

I also tried several songs from the Samples folder.

Incidentally, what do you have connected to the inputs? If it's an external sound source, is it the same if you completely disconnect?

I'm running 2017 (7) Release 1
