Maybe I'm trying the wrong thing in the Realband Piano Roll.

What I would like to do is generate or play on my Yamaha keyboard (no Pitch Wheel),a midi guitar part and then be able to bend the notes (or "strings") ala BB King blues or using a whammy bar in certain parts.

I thought Pitch Bend was what I wanted but maybe not?
Don't have the USB/MIDI cord yet so have to use Realband to generate the MIDI for now.

Generated a Midi Solo (Barney K Blues Guitar) using a Distorted Midi Guitar Patch
Opened the Piano Roll, selected Pitch Bend from the View Edit.
Went to the bottom window and drew all sorts of curves (using Control+Shift pen tool )below a variety of notes.
On playing them back I could notice no bending effect?

Are the Midi Solos blocked from changing them?
Do I have to remove or zero out some number somewhere to allow the Pitch Bend to work or am I using the wrong Edit selection?
Do I need to use a variety of selections to get that string bending sound?

Thanks for your patience,
Carkins
