Hi --
One more suggestion. Please take advantage of Michael B's StyleDump program and study Yamaha factory styles.
You'll see that chord note and type are associated with a Section overall, not the low/mid/high note ranges.
The most common use for low/mid/high note ranges is Mega Voice. An electric guitar may be defined in the following way:
Low: Root Fixed, Chord/Bass On
Middle: Guitar, Guitar Arpeggio/Bass On
High: Root Fixed, Bypass
High must not be transposed (Bypass) in order to handle special effect notes correctly.
Hope this helps -- pj
P.S. Thanks Michael and Peter!
