I recently purchased a used Ti keyboard, and have had very few problems.
In hardware mode I got satan's saw once, when flipping through patches very quickly while playing (I think I stacked up like 30+ releases)
Virus Control was worthless with Live 5, noise, sound cutout, etc.
So I hooked it up to my friend's comp with SX3, and it works good, only notes locking up here and there. I was actually amazed at how well the Ti integrated with Virus Control, sound card functionality etc. when it was connected to a configuration it liked.
I'll be purchasing SX3 very shortly.
