Hi Beepster,
I did get a chance to take Lexington out for a few runs.
At first glance, it was indeed snappier then Kingston (whoo hoo) and played nicely.
I haven't had any problems with midi, aux tracks, take lanes or the likes.
That's NOT to say I didn't have any crashes...
Had two -the second one was on purpose to see if I could repeat the first one.
It appears that one of my plugins (eventide ultrachannel) doesn't like it anymore if I change the track it's on from stereo to mono. When I mix, I typically change the Master bus from stereo to mono and pan to the left. This continues to work fine in Lexington. Sometimes though I want to check a track out for phase or whatever. Tried this out with the ultrachannel on it and it immediately crashed SP. Didn't do that in Kingston.
Didn't file report yet cause during the holiday, I would probe the forum to see if anyone else was having issues.
This post let me know some have (most haven't). I'll submit it and see if they've got a fix for it.
