Here is a screen recording from my iOS app, Verti-Chord Pro v7.7.7 (beta), which transforms a Casio PX-5S to emulate the FULL functionality of a pedal steel guitar (i.e., full portamento).
Guitarists, notice that the left hand is not playing piano chords. It is ‘fretting’ guitar barre chords.
Also notice that the right hand is not playing piano notes. It is ‘plucking’ fretted guitar strings.
Enjoy. Feedback welcome.
