I am using the Mod Duo X in the send/return loop of my amplifier, using input1/output1 of the MD X. This setup has been working perfectly since I got the MDX.
Now I have not used my MDX for a couple of weeks, and when I now try to use it, there is no sound. Just when I hit the strings of my guitar very hard, there is some crunchy sound audible, much like some volume is set to almost zero.
There is a perfect (bypassed, clean) sound when I use the bypass1, so I think the problem must be in the MDX settings or pedalboard. But even when creating a empty new pedalboard, with just one purple cable between input1 and output1, there is no sound (just the crunchy sound when hitting the strings very hard).
Device settings: Input gains are both set to 10%, stereo link is off. Master vol is set to 100%, ouput1 and 2 vol are both at 100%.
I have just upgraded to version 18.104.22.1685, but the problem was also there before the update.
What could be the problem?
