I updated my pa4x today and now I have no mic volume. It is dead. It worked fine before the update. All my switches are on including the Phantom power under the global setting. Volumes are up. Has anyone had this problem or might know what it could be? Thanks Ron

Sorry I just got a response from korg...it is a problem with the update and they are working on a solution. They said will be releasing a update soon...I hope sooner then later....thanks Ron

New version, 3.01 released yesterday, and it did address the phantom power problem, along with some others.

I finally updated. Went directly to 3.1.
Everything seems to work great. Screen is certainly different.
Some new sounds and styles. . .

Don did you mean OS V 3.0.1? I can't find the V3.1 on the Korg Website. This is for the Korg PA4X right?

Yes, 3.0.1
Sorry.
For 4X.
