Scene change not seamless

[posssu]

I have one track containing two audio loops with warping on in session view. Then I have a second track containing 1 Kontakt 2 Player.

I launch the first scene so the first loop plays. Then I play some stuff over it. Now I launch the second scene containing the next loop. The switch always seems to glitch and be a bit late. When I do it again right after it, this doesn't happen.

I've tried everything to make it smooth: frozen the track with the clips, clicked "RAM" on them (sholdn't this help?!! doesn't make any difference) and even put my latency to 40ms.

I don't understand what causes this delay/glitch with this kinda simple project! I guess it has something to do with playing the Kontakt 2 Player at the same time, but isn't RAM-loading samples supposed to prevent things like this?

Is there anything I can do to help it become smooth and the way it should be?
