@ therion - see wtreppler's post above. He got Win7 to work with J-Edit.
 
As I posted - J-Edit worked in Win8 as well for a while. Now it can't find a midi connection. My workaround is to use a Vista loaded laptop for J-Edit.

Therion, I don't have much to offer as I'm not at all familiar with your midi interface. All I can suggest is the following troubleshooting:
1) To make sure the program is installed and running as above, uninstall j-edit and re-install (and run) using the method in my previous post.
2) make sure that the j-station's midi in and out is connected to the same midi port (if you have more than one)
3) run only the j-edit program with no other programs that might use the midi interface. Make sure to "Run as administrator"
4) Make sure the in and out on your midi interface are (is?) enabled.
5) Double-check your settings on the j-station to make sure the midi is set up right (I don't have mine hooked up right now, so I'm not sure what they may be. Consult the manual)
6) Make sure your midi interface has the most up-to-date drivers for Win7 64bit
7) double-check both of your midi cables to make sure they're working properly
8) and any other troubleshooting you can possibly think of.
 
Try it with a different midi interface. Maybe you have a friend or acquaintance who has one you could borrow. I have a MOTU Midi Express and the j-station with j-edit work just fine.
 
Also, I know that when you launch j-edit it cycles through all the midi ports to find the one the j-station is connected to. It sends a "midi send" command to the j-station out of the port, then waits for input on the same port. That process can take a while sometimes.
 
Best of luck and I hope you get it working. I'm using mine in our Church worship band direct into the board with a Behringer FCB 1010.

Installing and running as an Administrator (which as sole owner/builder/user I am) allowed me to install and run the programs, but it failed to find the J-station via my M-audio/delta Audiophile sound card's hardware midi connection. (I can use my Yamaha keyboard connected to the same midi port with no problem).
 
I then bought and connected a USB midi cable, which windows says is working fine.  It shows up in the J-edit midi settings, I can select it and it still does not find the J-station!!!  I'm about ready to buy a new "J-station like" device, but I would rather not as I love the sound of the J-station, and have no way of knowing if any other device would be found by my ****ed windows 7 64 bit system....
 
If anyone has any new suggestions please post them here.

Quick note - J-Edit is working again with Win 8... or actually I should say Win 8.1. Over the past few months I noticed hard drive issues, the hard drive failed (replaced the drive). I believe part of my Win 8 OS was corrupted and causing various problems. So loading Win 8.1 over top of Win 8 tonight must have corrected whatever was stopping J-Edit from seeing the midi ports. Now all is well. And of course I will also send out a big thumbs up to the 8.1 OS. Everything works and works well. 

Hey musicroom,
Thanks for posting your results.

No problem Wally. Wouldn't have it going at all except for your helpful post. 

ok guys, anyone tried this with windows 10 ? I would think that this would go smoothly, having navigated through xp and windows 7 successfuĺly, but it would be nice to hear that it worked ok on 10 as well. certainly not a windows 10 deal breaker, but I just love some of the j station's models and working with j edit makes everything SO much easier than the "deep edit" mode on the front panel. I know it's asking a lot of something that has been out of support for a decade and a half, but hey...
