That is strange. Now it works as it should....
I will be observing the issue and let you know if the issue is back.
Nevertheless If someone who use MSP and Korg could confirm above I would appreciate it.

Hi Pietia,

I use a Korg PA4X with MSP and have experienced the same problem. It was also intermittent. Sometimes it worked and other times not. Sometimes it would load from MSP - other times from the keyboard. After lots of experimenting with software  options  I finally traced the problem to a faulty cable. I used and adaptor cable from the tablet, to a printer cable attached to the Korg. The adaptor cable was very weak around the plug area and I had several fail. I eventually got a much more robust cable adaptor and it has been going well for some months.I can't remember the brand of the adaptor and as I'm overseas at present I can't check. I will be home in a few days and will let you know then.
Cheers,
Rod
