I have a Korg M50 and also found this issue with 64bit DAW (Cubase 8 Elements) on a 64bit W10 machine
I can run the Korg M50 in an older 32bit machine running Cubase 4 on W7 and so I have interconnected these two PC’s together through MIDI, but it’s starting to get too complex to keep all the connections alive.
Has anyone found a good way to keep older VST’s working for older equipment? with either multiple Cubase machines or virtual O/S, or anything similar?
I have this same issue too on my Roland Fantom XR.
