Hello, Sorry but I think that you have the big job of registering all of your voices. I found this in the earlier stages. Pick a registration which, through the speakers, sounds quiet even at 127. Concert Guitar is one. Then adjust your main volume so this sounds good. After that, through all the reg buttons 1 to 8 adjust the sliders to try to equal the volume sound of your first button. Sadly you have to go through ALL of your regs if you want them to be of reasonable matched volume. I gave up on most of that, especially with the TTT Theater Organ voices, they are high volume sound and some of them need to be down to 30 or so to balance. I use my FC7 pedal to control the volume. Hope this does not deter you. Regards, Denn.
