Is there any after market software that would work with this controller since it is no longer supported??

That I'm aware of.....no

But if you write to PC DJ or Virtual DJ
They might add support if they get enough requests.

Will American dj make a midi driver software (not a dj software) or a game controller link software/firmware/driver (it's like when you setup up your game controller in the control panel) for the hardware so we can use the hardware with other software. PLEASE, PRETTY PLEASE.

I doubt any of those things will happen since there was such a low volume of units produced. I have personally owned one of these gems for six years. If anyone is looking for the factory softwware(since ADJ no longer supports the file) you can email me and I will send you the link.
