Hi Ed,

More information would be helpful such as what sound source are you using. So I am going into this blind but here is what I suggest.

You don't use the Mod wheel (CC1), you use the pitch bend wheel. I hope that is what you are using and not the Mod Wheel. If you can set the range you want to pitch bend to be in your software, usually a semitone or whole tone will do. Set the pitch bend wheel to zero, all the way down, play the note then quickly raise the wheel to the mid point. Subtle moves of the wheel after reaching the mid point will add a little vibrato to the note, something most guitarist do after a bend.

I hope this works and good luck.

Doc-take it easy John this is just a sharp scalpel. It will not cut deep so don't worry.
Me-I'm not John
Doc-I know, I am!
