Bob's technique is a very good one. But it depends on how many semitones your MIDI sound source pitch bend setting: In Bob's example it is set for 2 semitones, i.e. 2 half steps. Most all of the better sound sources allow you to set the pitch bend range while many GM programs do not.

I hope this helps.
