I love my Piano Morph keyboard, but still long for something more. What could be better than a 4 octave Morph with full-size keys? If 4 octaves is too large then 3 octaves is still better than 2 for two hand playing and wider range of pitch.
The 4 octave keyboard should be a solidly constructed and it would be nice to carry the keyboard around without the overlay falling out.
I like the design of the Roli Seaboard keyboards, but I’m not a fan of the wave-like key shapes. I find it is easier to slide from note to note on the nearly flat Morph surface
