I can no longer access my midi on usb. It worked well on earlier OS, it has been sketchy since I moved over to W10, it would lose my midi ports or they would lock up with a memory problem. I could fiddle around with things sometimes and get it back but I can no longer do that even. The ports it 'sees' are the wavetable and MIDI Mapper, but not either of the cables I have been using in the past. This occurs on my scoring program and on the VanBasco player as well. Please help, and thanks.
