My apologies. I have limited computer time and this stuff... which would take 5 seconds with a 'pro' in the same room, takes -ages- online. This PC is not the one I DAW with so from faulty memory:
What I mean is that, I put in a keyswitch at bar -1 for, say, perf legato. I hit 'Play' and off we go to the next -two- keyswitches at bar 50:
1. C#1 Switch to the 'Articulations' matrix
2. F# Switch to the 'Pizz' patch
At bar 55, I hit 'Stop' and use the mouse to go to bar 47.
I then hit 'Play' and... I still have Pizz... even though this is 3 bars before the keyswitch. That's what I call 'chase failure'.
I see in your sig you use Nuendo. Maybe it's different somehow?
