I have a problem when I play constantly on the sound "KRONOS German Grand" ,after a few minutes of playing, the volume suddenly reduce by half, and return back to normal after i change to another sound and back to "KRONOS German Grand"?
Any idea what could be a problem?

The same happened to me, and i couldn't for the life of brian understand why, until i realized that my iPad, which i had on top over the display, came in contact with one of the sliders...

I had somewhat a similar experience but with a brand new PA3x...My iPad was also just sitting on top of the keyboard (at no time it came to contact with any of the knobs or sliders at all). Also, there were no physical connection between the two....As soon as I removed the ipad it came back to its normal state. Some kind of electrical/magnetic interference? When I put it on its own stand which holds the ipad by few inches above the keyboard, then everything works fine here.

Is your keyboard connected to anything? Does it only do it to that particular sound?

Is your master level up half way and could the vibration of playing the keys knock back the volume to half way?

it's the master level moving..

The Vector Joystick is also a prime culprit, although I'm not sure what it's set to control on SGX-1 patches (I disabled it on my usual piano sounds).

Same problem here since yesterday.

After 5 minutes aprox the volume fade out. I took away the IPAD and discconected expr pedal :s

Any suggestion?

It seems that the Midi Keyboard Controller that I had connected to Kronos was sending a cc07 message. So I think the problem is solved now.
