Yamaha does a great jb with 3+ dinger chords - even jazz, rootless chords. The simple method I prefer works like this. Using just 2 fingers, I get Maj/Min/7th - all else requires 3 or more.
If I press:
C - I get C major
C+Eb - I get C minor
C+Bb - I get C7

This relates to the theory practices of building chords, and makes more sense to me. Sounds like you use 3 notes or more, and that's terrific. Probably very common for a pianist, or organist. I was a bass player before I was a piano player! LOL
