I think store amp-module saves the amp to browse-mode. But I‘m not sure. Search for it in browse-mode.
It is normal behaviour. Any tweeking in particular performance has to be saved as a whole performance.
this is normal behaviour. I believe store Amp Module would create a preset rather than a rig
Yes, you are storing your amp volume modifications in amp presets instead of the Performance.
As Burkhard said, saving the Amp module saves a preset for *just* the amp module. That preset is saved outside and completely independent of the performance.
The only way to save your changes in the performance is to save the entire performance. This goes for making as little as 0.1 value change to one parameter. You will always save the entire performance.
That may sound like overkill, but to me I like it that way. ONE way to save changes in a performance...instead of various ways you need to remember.
Ok - got it! Thanks for clearing this up for me
