I´m glad to hear that. Could you be kind to write what driver you use and I think PA 4 and PA 3 use the same USB midi connection and driver software. Maybe it has something to do with the tablet. You use a Surface, I use a Samsung TabPro, but both tablets are running win 10. Weird...
Best regards,

I think you are correct when you say it depends on the computer. I have no problem connecting the Pa4x to the Surface Pro its recognises it most times (sometimes I have to reboot, but rare) in fact I did not load the Korg USB-Midi Driver the surface Pro it just recognised the Pa4x and shows up in connected devices as "Pa4x".

However on my desktop where I have to use the Korg Drv Tool (1.15r18) to connect to Cubase after a lot of exploring found that the desktop only connects when I plug into a specific USB port!  A lot is written on the Korg Forum about this topic if you search under USB-Midi you might want to try some of these tips/tricks

Sorry I cannot be more specific but I think the problem is the Samsung TabPro not recognising the Pa3x connection, not MobileSheets (Win 10)  as from my prospective it works very well

I use Korg´s Drv. Tool 1.15r18, I think this is the only one intended to all of Korgs USB-midi connections. On my Samsung TabPro it is present on the Device Manager and it works well in Sibelius and Cubase. But it dosn´t shows up in MSP. Furthermore I tried all 3 apps on two of my win desktops and the result was the same. With MSP in Android the connection works fine withoult any driver.
