Hello All
Both of mine (firmeware and HX Edit) are 2.7 ans I have the same issues.
On HX Display: All slots in grey <EMPTY>
On Pedalboard: IR is available as parameter with the right set up regarding the Patchsound
When I try to Import, the name is dysplayed in the list but looks like "desactivated", and no way for "saving" it in the list, it goes away when stop/re-start HX edit...
Cheers
Tof
