I can't seem to be able to use both Midi 1 and 2 at the same time. I am playing a midi sequence and playing SD40 lead over it. When I choose Computer and sequencer, the midi is great,but I get no voice from the keyboard until I switch to "Standard" midi config.,and no sequencer sound. It seems either/ or. The midi jacks are in the right place.

I couldn't reach AJ,and thought someone might know.
