I think I have found a bug with the new Dyami-Comp models.
This can be recreated with a new preset with only an Input Block, Comp Block and Output Block.
Best way I can explain is when switching between channels in the Comp Block, if there is a Dynami-Comp type in there the volume jumps up or down depending on the compression level, but at a level it isn't actually set or saved to.
Say you are using channel A with Dynami-Comp-Classic selected and then you switch to another channel, lets say channel B with another instance Dynami-Comp-Classic or any other Dynami-Comp type, the volume may now be much louder or quieter than you previously set or saved that channel to.
The graph in Axe Edit also shows this. If you now click on the same channel selector letter in Axe Edit (we are on channel B, click B again) you see the graph line revert to the position it should be to correspond with the settings and also the volume return to the level it was also supposed to be set or saved at.
This can also be triggered by clicking on the active Comp Block on the grid in Axe Edit after selecting a channel with a Dynami-Comp type present, the volume will revert to what should be the correct set or saved level
I have firmware 28.0 Beta 4 installed and the correct Beta version of Axe Edit (1.14.10) installed to match.
