[JW Lua] JW Lua to change pitch wheel value

[Harald Schollmeyer]

I would also suggest you first have a look into the MIDI standard  
concerning pitch wheel data -
it's up to the sound producing unit (which can be software or hardware)  
what is being changed
by which amount if it receives pitch bend.
On a lot of sound units, you would get a bend of +2/-2 semitones up or  
down, but this is far from
being universally true. It's hardly possible to predict/determine exact  
frequencies or pitches when
sending pitch bend data.

Just my thoughts...
