UPDATE...

i have FINALLY figured out what's up with my Bass Guitar Dropouts
i want to APOLOGIZE for thinking or blaming the AUDYA 4's new 4.2b OS

it was not the OS
it was not a power issue
it was not an AUDYA4 hardware (bass slider) issue
it was something quite simple and non-AUDYA related

what was causing my Bass Guitar Dropouts was my Controller, my AKAI MPK61

specifically, it was my second slider which i had long ago assigned to control my Bass Volume
this slider was somehow stuck, constantly sending out Midi Channel 5, Controller 07, Data/Vol 00,
so it was dirty i assume, or stuck sending this Volume Off to my bass,
all i had to do was move the slider on my CONTROLLER a few times up and down, and all is good now

again, sorry if i scared anyone away from updating or gave the AUDYA some "negative" criticism
and sorry AJ if you wasted your time looking into this.

i'm just happy that i can go into this weekends wedding gig knowing that my bass player will show up :-)
