Hi Noel,
Thank you for the quick response. It seems to be working now but I'm not sure why... I haven't changed anything. Here are the answers to your feedback but at this point it might be for academic purposes only.
I'm using M_BZ128.STY
1) The Piano row in the mixer is blue (1886:Piano, Solo-Accompaniment Bluesy 12-8John Sw 060) and the Bass and Drums are yellow.
2) The Piano line of my Plugins tab looks just like yours and all the others say ->[Default Synth]:None
I do have 818 update installed.
Thanks again for the suggestions. I'll start by checking these things if it stops working again.
Joe
