Windows 7 - hooking up midi keyboard over jostick port in windows 7

Hi I've just switched to Windows 7 from xp, and i used my yamaha CS2X keyboard hooked up over midi joystick port on my Audigy LS to control and play music in Reason 4.0 and it worked great in XP. Now in win 7 i cant even select the midi in port i want to use, so i was wondering how would i get midi to work in reason with my keyboard?

I had to use Daniel_K's driver pack (There are links on these forums) to get my Audigy 2 ZS working in win 7 64bit and it now works a treat. Infact when i first put the Audigy in Windows installed it's own basic driver for the midi port and WDM drivers for the card. I just prefered having some proper drivers running.

In the process of trying to find the solution i was told many times that Microsoft had stopped support for the old midi interface once Vista was released but i refuse to believe that seeing has i have mine working.

Oh i also run a XFi Xtreme Music card as my main output device
