PT 31 by DAVID RAMOS “Darwin” on Flickr.
The only difference between the PT-30 and this beauty is the colour. The former was released in the classic Casio off-white shade. This little guy lacks some of the qualities of the Casio VL-Tone and PT-1 but it does have single-finger chords so you can select a chord by name and press one key. One other thing this Casio sports is 18 preset rhythms including a white noise cymbal sound. I’d love to get my hands on one of these… of course, don’t I say that about every Casio?
