The KFC1 keyboard chord finder and its database of 2000 keyboard chords is just so useful to have around. All you do is press a button and input the chord's name to get a graphic display on the LCD keyboard. Press the INV button and you can see different inversions of the selected chord. The FIND function lets you search for chord names.

There's a BASIC display of rudimentary chord shapes and for beginners, four-note chords can be abbreviated and shown as three-note chords. The AUTO POWER OFF extends the battery life.

The KCF1 - possibly the ultimate chord book that fits in your pocket.
