I had a similar problem w/ korg legacy collection.

Try opening a stereo/ instrument track.
I was not able to find my instruments while using a mono instrument track.

Once I used a stereo instrument trk. there they were on the drop down.
Prior to that I was only using mono to record audio.

Might work. I dont know if you tried this yet, sometimes the simplest things are the problem.

Best of luck. Bill
