I’m still having this problem in 2025. The H9 will just stop reverbing at all.

I can see by the meter on the H9 and in the app that it is getting signal.

But no reverb, pitch or any other kind of effect.

I do not have MIDI connected at all. It’s just an aux send on a mini mixer for somesynths.

1 input, 2 output.

Seems to pop up after a preset change.

But not every preset change.

The last time this was driving me crazy I found some fix that involved changing the bypass mode or something.  It had to do with using the app to change settings one way or another.

But now I can’t find that solution anymore.
