Hi Doc,
Korg, Ketron, Roland have similar systems. ie style tracks can be created for between 3 maj, min, 7th for (Ketron & Roland) up to
6 (Korg) different chord types for the different style parts.
Technics had it's own system, & so do Yammies.

My version of a psr/omb style it could have some flaws. ( Jorgen if I've got something wrong please correct me)

Intro's & Endings are usually a mix of melodic phrases & Chords. They are also able to have a chord progression in them. Normally you'd create maj & some minor tracks because melodic lines don't always transpose very well.

Chord track variations are created based on a maj7 chord. Have to have the maj 7th or it only plays maj or min chords no matter what type of chord you play be it a 7th or a 9th etc.
You can also have melodic phrases in the variations. Usually handy for melodic phrase to have a maj & min version.
Definately no chord changes allowed in Variations.

Fills similar to variations except they don't repeat.

Basically styles get transposed up & down.

Don't know how much help I can be. Trying to explain it isn't easy

best wishes
Rikki
