It is funny because I do believe that fourths mode is very intuitive. You get a larger span, the chord shapes in the end Are slightly easier to move around in, and from a chord progression standpoint it is highly effective. Also the familiarity for guitarists, and the chromatic mode is pretty easy to grasp.
But in thirds mode rotated, you can do a triad simply by hitting three consecutive pads in a row! It feels a lot like a piano. Inversions are very easy to constrict as, each new root row for a chord starts one up and to the right from the fifth of the previous chord. I'm slowly grasping the idea of fourths being at diagonal from lower-left to upper-right (or I think, I woke up with the notion, about to test it!). What is also fun is how it being flipped sideways, as you raise tone your finger moves upward. In some cases this feels very exhilarating! (Don't knock it til you've tried it!)
I do admit, you only get a very inefficient three octave key span.
If anyone has anything they'd like to share on the concept of playing in thirds mode, please share here
And finally, a pleasant video of the legendary Ableton presenter Huston Singletary:
