Scottyee,

The following is my finding about your chord recognition on Korg I-30, Roland G-1000, and Solton X1 (OS level: 3.0a):
X1 I-30 G-1000
----- ----- ------
F-C-E FMaj7 FMaj7 FMaj7
F-B-E FMaj7b5 Fmaj75b Fmaj7b5
E-A-D Asus E7sus4 Asus
B-F-A B5b7 B7b5 F5b
X1 I-30 G-1000
(Eb - A - D) (G - C - F) F13 EbMaj75b EbMaj75b

Unless Solton has changed chord recognition in their later OS software for X-1, the X-1 does not satisfy your rootless chord requirement. There are only 3 chord types in Solton X-1: Easy1, Easy2 and Fingered. I tried all 3 and none of these recognizes your specified rootless chords.

Good luck in hunting for your next keyboard.

Thanks,
