Why can't you use it with Win 10?? I'm using a MUCH OLDER SC-8850 (and a lot of other stuff with NO USB plugs at all XV-5080, Alesis QS8, QSR, Nanosynth, ...)

You MIGHT not be able to use it OVER USB (but with a little hacking you might be able to - you might want to do some "googling" on it) BUT it still works over 5-pin DIN MIDI.

That aside - if you only want a GM compliant plugin then it's fairly limited: TTS-1, Coyote Forte, the IMO the pricy ($125) Roland Sound Canvas VA, and some others that require a little effort to make "GM-like" (like IK SampleTank 2 with Omnisynth add-in, I'm probably forgetting a few but there really aren't that many that you install and use like a GM module VSTi)

If you don't mind assigning your instruments by picking the patches manually ANY VSTi softsynth: Kontakt, Rapture Pro or Dimension Pro, Sample Tank 3 (or 2) , Garritan, UVI, Xpand!2, or any SFZ, ...


Good Luck
