I’m sure that somewhere, someone has commented on this but I think it is worth a try to say again. When I reopen a project in N6 that had channel and rack configuration presets, the presets are gone. If I re-create/save one preset then the others all come back. Reopening has then disappear again.
Also please make it so that the mixer doesn’t have to be in focus in order to recall a preset. This is a needless mouse click especially because the mixer presets are exclusive to the mixer. I hope this fix is on the list already.
