GP-10- Cant change patch volume on GP-10

[JoBoss]

Hi folks!!

I tried changing the patch volume via the processor (GP-10) itself, but it jumps back to the previously set patch volume, after I write (save) the patch with the new volume setting, go to another patch and then come back to the volume setting changed patch.  Any idea how to permanently make changes to patch volume..?

Another problem of recent is that the E string (first string) gets muted in modeled patches like sitar, but not in non-modeled patches.  Haven't changed sensitivity or string distance on the GK-3.

Could that have anything to do with my 13-pin cable.  The problem is intermittent, happens only while on some rigs, not always.  Any ideas anyone ///

* backup all your gp10 patches and perform a GP 10 factory reset

* then check your GK13 cable - clean it
and or replace it

The jump in volume can also be an assign. Check your assigns. If you control patch volume from the GK vol pot, it could be an issue with the GK cable.
