Casio Chord

From SoundClubLibrary

Casio Chord is Casio's simplified system for playing chords on the accompaniment keys (usually the first 18 keys on the keyboard) of their keyboards.

In Casio Chord or fingered chord mode, these keys produce a bass sound and an organ-like sound, rather than the currently-selected patch. When Casio Chord mode is selected, pressing one key elicits a major chord in that key. While holding this key:

• Pressing any one key to the right of it changes the chord to a minor chord,
• Any two keys to the right produce a major 7th chord, and
• Pressing any three keys to the right produces a minor 7th chord.

[edit] Variations of the Casio Chord system

Some models also feature "variation keys", allowing for complex chords to be played with two keys (i.e. F# + min7 variation key for F#min7).

Also varying between models is a "latching" behavior mostly present on newer Casios (the oldest known by the maintainers to behave in this fashion is the Casio CTK-150, but little information is available about this). Originally, pressing (for example) C and any key to the right of it would produce Cm, and releasing the key to the right would cause the keyboard to immediately return to playing C major. However, on many newer Casios, pressing a key to the right of the fundamental causes the chord to change until all keys are released. Additionally, there seems to be a slight lag, such that releasing (for example) the bottom C and pressing the G above it immediately after will sometimes elicit a C minor chord rather than the expected G major. This behavior seems to be present primarily in those members of the CTK series marketed for home use.
