I tried following that post and got nowhere... Not to worry... 

I tried the Drivers for 8.1 but the damm thing wouldn't load for my PCR-500, I also have a SD-90 that I would, like to get workin again.

Hey got the PCR-500 to Work tested it a little seem to be good. The Sd-90 is another thing haven't had any luck with it so far. theres another post on how to set it up better explained after a lot of trial and error yahoo, if I can find it again i'll post a link

Hi there,
I just bought a new desktop for Christmas using Windows 10 professional and I was really surprised that my Roland PCR300 Controller keyboard was recognised straight away by the Windows operating system and the drivers were automatically loaded. All the connections show up in Sonar Platinum under preferences/midi in the Midi Input and Midi Output fields. Roland have no Windows Drivers for Windows 10 so I decided to connect the PCR 300 via USB before trying to load any of the available drivers and it worked straight away.
Having said that, I need to spend some time over the holiday period to see if ACT will work with my PCR 300 as it did on my older PC using Windows 7.
I notice in Sonar Platinum that the PCR 300 does not show up in the list of devices under the pull down menu for midi controllers as it did under Windows 7 and Soar X3.
Will keep you posted.

Sorry about the typo. It should read Sonar X3 which is what I have been using until recently.
