Gary,
Missed your calls - played multiple gigs today. There is no Aux line out on the KMA. I'll keep experimenting with the various options until I get a good setup. I tried again today using the headphone output and using three different record levels from 25%, 50% and 75% and all three were distorted. The real challenge is most of the styles have different volume levels and it is tricky to get the record levels set for a gig. I tested it on my T4 it worked perfectly - really strange.
