Larry, yes I had that problem with my 6500. I also found that if I activated the demo button everything worked fine. I found the root of the problem. Some others had experienced this also and I helped them out. The problem lies in the expression pedal. When the sequence was saved to disk the expression pedal was set to zero volume. Therefore when reset, it turns off the volume as it was saved originally. The demo button resets the volume to the on position. The disk that gave me this problem was a professionally done product by, if I remember right, Dennis Awe. After I found the problem some of the old organ guys that could not play unless they always used a swell pedal had the same problem when they would save things. They would turn there swell pedal off or down and could never get any sound or very little. The first thing out of their mouth was my board had a bug or it was broke. The easiest way to fix the problem is to press the demo button get it working and then re-save to disk. No more problems. You can also go into the operating guts of the board and adjust the volume but you still have to re-save it. I always like to take the easiest road to my destination. I’m almost positive it aint broke, just a glitch in the way things were done by the operator. Man, I sure enjoy your playing!

Another problem these old organ players and also others is that they regulate the volume by the Acc/Sequencer volume slider. If they save the sequence with that slider turned down they go nuts with their volume doing all kinds of crazy things. Always be sure that slider is turned to full before you save.
