without going into a 20 page description, if you have 2:3:3:2 pulldown on your VTR (like the Panasonic AJ-HD1200A, or the Sony JH-3), your program will play out at 59.94 into the FCP system, so you will NOT edit in 24p mode, and you DO NOT need tri level sync. You only need tri sync if you are working in 23.98 or 24p mode, and unless you are finishing for theatrical release, I see no reason to do this. A nice boring black generator will work just fine, as long as you keep your material at 59.94, and not 23.98.
The Multibridge Studio WILL have tri level sync. The only times I have been forced to use a tri level sync gen (like the Evertz 7750, or the Ensemble or the Astro Systems) is when someone ACCIDENTALLY wound up with 24p tapes and
a VTR like the HDW-M2000/10, which DOES NOT HAVE 2:3 pulldown as an option. THEN you need tri level sync.
