I understand what you are saying that havingthe Pro as master means that it cannot possibly drift.... Its science right!!
I still have a theory tho, call it conspiracy theory if you like, that the Pro and KP3 internals, ie clock timing and audio loop timing are not accurate. This would lead to the audio playing drifting from their own clocks!!
Have a read on the innerclock system website. Its very interesting.

There is a page on it where they use a modified midi cable to convert clock clicks to audio, then examine the audio and check the sample count between clicks to determine a units accuracy.
I bet if you recorded a Pro audio output running standalone, and similtaniously recorded the clock output as audio, you would see the timing drift within the unit.
Anyways, I got a reply from Korg. They said that shouldnt happed and are looking into it. I will post the findings.
Keep up the good work Bowmoney.
