One button Automix on Denon HC4500

[BungleBear]

Hi guys

New to the forum, well not really, was here years ago but recently came back.

I came back coz I bought a HC4500 and it wasnt working right. Dont know what the issue was, but I downloaded a new ohml file (I think thats what it is called) and now it's working great.

Thanks for whoever wrote that. (I'm guessing someone called Andy as it called +DJ Andy)

But, the question is, to automix (or just fade one song and start the next, i think that's called Automix), you have to press both "Back" buttons.
Quite often I work one handed (mixer in one hand, mic in the other), so would love to be able to do this using just one button...
Any of the five buttons across the top would be fine - i dont use video and I dont really mix much, so loosing one of them wouldnt be a disater

Thanks

Dale
