Found the problem:
Apparently the only way to initialize this puppy is to hold down the demo AND the last white note while starting up.
Results--it initialized and brought the vol up and the sound is much much improved. I think maybe with some tweaking I can now get the voices to sound something like the demo and hopefully Simons Stereo.
One of the reasons for buying the the Yam speakers is I like monitor/s in my face it lets me hear what I'm doing much better, and don't like ear monitors. But I know they're not getting a good rating, so torn between giving them a try, or taking the Z5500 system and custom build the 5 speakers to mount on the hardware bracket that I built for mike stand, laptop stand, mouse pad arm. This bracket lays between the keyboard and the L7 stand. and thought about mounting in front of the keyboard 4 speakers 2x to each side facing forward and the center speaker being a monitor facing me.
I still have a second z5500 system with Gary's (Travl'n Easy) setup with the stands etc. for playing outside the studio when needed.
To each and everyone who responded, I thank you very very much.(Whether the suggestions are the correct answers or not It makes a person think and between all of us we got it) I'll sleep tonight...
(be dream'n of being a big tyros 2 rock star..with young ladies hang'n all over me)
