Editing a Midi program sound.... disabling vibrato on the Pitch Bend Bar

[Roy Howell]

Thanks for any help...here's the scenario...

My sound module has 2 separate effects possible per Program sound(piano, guitar, whatever...). I have one effect Disabled, and am dealing with just ONE effect, right?

Now, on the pitch bend bar, it can be programmed to be a WahWah when pushed forward. OR it can be vibrato. I want straight Wah ONLY(which I've set it up to do), and no vibrato, but the vibrato won't go away.
Do any of you know where I might possibly disable vibrato, given that many Midi devices are similar in this type of setup?.....

So to sum up, I've got one effect (distortion) on this Program, the Pitch Bend is set to Wah, but it also triggers Vibrato, which I DON'T want. How do I disable Vibrato?

Thanks, Roy
