Donny: the specific 'rootless chords' voicings I outlined over the years here works fine, and in all 12 keys.
These are 3 note altered versions of the most commonly understood & played by jazz pianists II-V-I '4 note' rootless jazz chord voicings (both A & B variety)
of which I've repeatedly outlined in detail, and now supported on Technics, Yamaha, Ketron and Korg arrangers.

Of course there will probably be other variations of rootless chords that aren't recognized, but until an arranger manufacturer adds a custom 'user definable' chord recognition palette feature,
I seriously doubt these will be added to the existing palette, especially if the chords already serve a duo function recognizing the chord voicing as something far more commonly understood. Because of this limitation, the addition of a "Chord Sequencer" is a good way to get around that problem. - Scott
