Will two KP3's keep time with each other without midi?

[robosardine]

Hi - I know there are midi clock issues with them. But will two keep time with one another. E.g. Feeding drums machine patterns into one and sequenced synth parts into another. I am guessing they should. And what about when you are switching on and off the eight mute/ button things- can you do this freely on both with no timing issues- or will it soon drift into mush?
Thanks
