Pitch bend wheel works on SI bass. As does drawing them. I've been checking these things as I talked to you.
How did you insert SI Bass? I usually click the + button in the Browser, choose "Insert Soft Synth" "SI Bass" etc. You then get a dialogue box, and can choose (amongst other things) "Simple Instrument Track" or "MIDI Source" and a choice of "First Synth Out" etc. etc..
Anyway, for now, click on a note in the PRV of the SI Bass track and look in the "Events Inspector" in the control bar at the top of X1 or X2. What channel is it showing? If it is not the same as the channel you drew the wheel controls in, then that is the problem.
It's nearly 2 A.M. here, so need to head off to bed soon. If I don't hear back tonight, I'll check in tomorrow. P.M. me, if you want.
