Well I certainly hope that the "Give All Keystrokes to Plugin" and the Fast Bouncing of time/tempo based effects are fixed in X2.
I've been pulling my hair out (stupid me !) with these two things for the last two days.
If I remember correctly, both of those were fixed in X1c, and are broken again in X1d.
It's caused me so much frustration, I've been tempted to roll back to X1c at times, but then you lose all the fixes in X1d ... Arrgh !.
Here's hoping
