I think the OP is talking about an FC switch. The FCs don't send midi. They have specific functions for scenes.I must misunderstand your question because I don't know why people are saying "no". I have a momentary midi switch right in front of me set up to do just what you're asking for. A momentary midi switch that sends the CC value for scene 8 when down, and the CC value for scene 1 when up, seems to me does what you want.
Well, actually, rereading your previous reply, your answer is not quite a "momentary scene switch". In my mind, that would momentarily change to a designated scene and then return to whatever scene you were on before pressing the switch.True, it can't be done with an FC, if that's what he meant to say. But couldn't a midi switch still be the answer to his question?
Or Scene Toggle on the FC... Basically the same thing except I don't think that's capable of being momentary.The closest you can come is what I described above.
