matrix6 no sound out

I was playing with my matrix 6,used it to control a drum machine,when i went back to
play the keyboard no keyboard(sound out),local control is on,stereo is on,unit still will
control another unit and display all info,patches,edits etc,i can here a hum on the output
when i turn the volume up and down . I also reloaded all the patches(thanks Matt) still
nothing....any ideas or more ideas also who owns oberheim
now??pgoeltz@earthlink.net

If you had a volume pedal in before using the drum machine and it's now out , try putting it back in and make sure it's not zeroed. Or if it was in all the time try taking it out. Remember not to touch anything while powering it up because it does some calibrations at that point. Just shooting in the dark--I have the module but if it's a system problem it sounds like a conflict on the MASTER page.

**Gibson now owns Oberheim. And there is one less dealer as they apparently have ticked off Musicians Friend. Good luck.mn
