Hi Brad,
Please consider the following suggestion for inclusion in a future OS update (and also in future Casio arranger-type keyboards)
Current functionality:
Fingered 1 and Fingered 2 modes permit playing chords in any inversion. The bass pattern follows the root of the recognized chord.
Fingered 3 mode, also known as "Fingered on Bass," recognizes the lowest played note as the bass note, and alters the bass pattern of the accompaniment accordingly.
It's not clear from the manual whether the chord recognition mode can presently be selected or changed by pressing a foot switch.
Therefore I would like Casio to add a new function to the footswitch menu. This would be a MOMENTARY function (i.e., like Sustain)
When you press the footswitch, and for as long as you hold the footswitch down, Fingered 3 mode is in effect
When you release the footswitch, chord recognition reverts to Fingered 1 (or perhaps, whatever fingering mode was selected previously)
Having this functionality would make it much easier to play songs that have mostly "normal" chords and the occasional slash chord. Most of the song's chords could be played in their familiar, comfortable inversions with a minimum of hand movement. When the odd slash chord arises, you could press the foot pedal, play the chord in a specific inversion to specify the bass, and then release the pedal to continue the song.
Glad to discuss this proposal further via private message or here on the forum.
Thank you in advance for considering this suggestion!
