Superior Drummer no longer recognizes TD12 midi

[zv yoda]

Hi folks,

I'm on PT 9.0.5 on a 2011 i5 Macbook Pro. I use a TD12 to trigger SD2.2.3. Everything was working swimmingly until tonight. I suspect it's because I recently installed Lion (although I'm not 100% certain).

Basically, SD no longer seems to see the midi from the TD12. It's not a hardware issue from what I can make out. The TD12 is fine when I use it's now brain/sounds. I checked the midi cables (they're fine). My Digi 003 rack sees the midi signal (the green "midi in" light is illuminated). I can trigger SD using my Axiom keyboard.

Any ideas? I'm stumped. Maybe it's something obvious, but I've been working with this setup for 18 months & it's always been rock solid. The only recent change I can think of is the Lion upgrade - but maybe that's just coincidence? Is is possible Lion has messed up the internal midi files or something?

Any help greatly appreciated!
