Tried with Matrix12 and MS20 and a few others but suspect its a system wide problem with the new browser: Windows 11. Fire up Komplete Kontrol and select a patch via the Kontrol browser - works as expected, the instrument loads up with the correct preset; also other presets can be selected in Kontrol as expected. BUT now select a patch via the Arturia browser within the instrument - patch loads OK but now presets cannot be selected/changed via Kontrol anymore (they are still auditioned ok) until the instrument is removed and reloaded into Kontrol.
