@David-Healey Thanks. Once I removed IsPluginParameter from all sliders the interaction is gone. Before I removed it from all it interacted with the next one. As I understand, this will eliminate writing DAW automation for the controls. I guess I can start this way and hope for a fix in the future. Should I report it under bugs?
In any case thanks for the help. I did enjoy your Bootcamp and hope to use HISE successfully and start scripting soon.
