Tried preliminary Owlware firmware V22.5.rc4 on Witch

When I push the buttons the patch freezes and doesn’t process any inputs anymore.

Thanks for giving it a go, hopefully @mars will be able to resolve this soon enough if there’s some problem with Witch firmware build.

Which version was previously installed? You might try erasing patch storage and flashing patches again as there may be incompatibilities between reading and writing patches on different firmware version. There’s been no recent Witch-specific updates recently, so I’m not sure if this issue will end up reproducible easily.
