Press the SETUP key 3 times, until you see the following 4 softkeys:
midi external dump nextprog
the layout may be a bit different as I'm on the H8000.
What we need is that [external] menu!
Press its softkey to enter the assign 1 setup page. Now set mode : high, using the knob. On the left bottom of the page you should see a bar filled up to 100% once "high" has been selected. Go back to Arkham Distortion and check that menu I described in my previous email.
Do you get sound now?
