PSR-E343: Set key signature?

Unread post by herecomestheflood »

Is it possible to set the key signature for this keyboard? Like, if I'm playing in A, I'd like G# to show on the staff display as G#, but it's showing as A flat.

(Experienced sight readers might think "but G# *is* Aflat!" But when you're new to this and using the display as a tool to confirm what you're reading from the score, it's enough work to keep the key signature straight as it modifies notes, without having some notes appear on different lines on the display than on the score.)

I don't think you can do anything or set anything to change whether black keys are displayed as flats or sharps on the LCD display, except possibly when you're playing specific chords in the auto accompaniment section.

With the black keys, my guess is that the keyboard most likely gives preference to using one name or the other for a given black key based on the circle of fifths:

Starting at C and going up a fifth: C, G, D, A, E, B, F#, C#, G#, D#, A#, E#, B#
Starting at C and going down a fourth: C, F, Bb, Eb, Ab, Db, Gb, Cb, Fb

Notice that Ab occurs in fewer steps (down 4 fourths from C) than G# does (up 8 fifths from C).
