PS I'm not quite sure how I did this, but I eventually succeeded in getting my new song Opened, but what I hear is not what I hear on my PC. I have the melody disabled in this version of the song, and use the _JWALTZG style.

What is played on the iPad is only the drums and the (MIDI) melody - no bass or guitar.

I appreciate that this isn't an expensive product, but I don't expect to be having to do the beta-testing.
