I guess the old MIDI would work, don't have a matching power adapter for the A-800 though atm.
I am not blaming MS for all these driver issues though and I bought a Roland when it was Windows "8 party and they got new drivers back then.
Also, not even owning a Nvidia, over here, their driver reputation is great on forums historically, so, I don't get it.
Sad to see excitement do sudden U-turns though at peoples houses for what ever reason especially all the problems that should, be, un-necessary, prevented etc, I read you softie.
Funny how my age cuts in half when i'm whiney and doubles when i'm serious'ness, although, Peter Pan for evah!
