Implement chord families to be able to cycle through chord shapes while playing

[mickmister]

As I'm playing kyboard, I may be changing the settings on my keyboard, which can change the behavior/sound of each octave of the keyboard. Because of this I want to be able to change the chord shapes to adapt to the different sounds.

For example, I may switch to a synth patch that I just want root and fifth in the bass, but then switch to another synth patch where I want double triads in the mid/treble.

This is a fairly large task, but I think this is one of the most important features of what I'm looking for in jamtools.
