"I would love it if my T2 understood my rootless voicings. Being able to play in full keyboard mode and play jazzy voicings would be a blast." quote montunoman

You can play rootless chords on the T2. Yamaha has been doing that at least 10 years. There is a slight difference in the notes used on some chords.

But try:

Dm9 play FCE.

G13 play FBE.

You'll be able to see it in the chord display as well as hear it.
