I think, we had this kind of issue handled earlier sometime, or at least something similar… have to search the forums.
I know i had to correct it via GP-Script. I just tried on Blue-3 and there are two problems that occur with the chorus/vibrato button:
in the plugin, it’s an endless button (at least in Blue 3)
That parameter starts counting with 0 on “V1”, but this position is on 4 o’clcok, while the first position 0 of a widget is at 8 o’clock, while the plugin is already at “C2”.
So we have to send the widget the corrected values so that the sequence will be V2, C2, V3, C3, V1, C1
that way the position and setting would be “in sync” again.
EDT: Got it! Maybe this is helpful…
