Hello Rich

did you ever try to feed your external audio signal directly to a
standard module like e.g. A130 VCA or A138 Mixer How does the A100
signal compare to the original signal there The A138 should be the best
possible signal an A100 can produce with your audio. The A130 should
provide the average possible signal quality.

Maybe you expect too much from a modular system like the Doepfer A100.

And still the output impendance of your external signal might cause the
trouble. What exactly is the source of your external audio - I mean, to
which device belongs the socket which is connected to the input of the A100
