Calling all my circuit benders and analog collectors!!
Casio PT-82 mini keyboard with it's original box and accompanying ROM-Pack "World Music". Everything works as it should, no major damage other than some light wear. The box has some taping on either side but the graphic is in excellent condition and is overall very sturdy. The battery case is very clean with no corrosion, it's all good and ready to go.
From the nets;
"These are very basic, monophonic, semi-toy keyboards. A choice of 12 rhythms and 8 voices is available. When playing the keyboard manually, only rhythm (consisting of 'blips' and noise pulses) is available - there is no chord accompaniment. Despite this, the ROM-Pack music is still rendered quite nicely, complete with chords and two-voice polyphony.
In common with most ROM-Pack keyboards, the four-level "Melody Guide" training feature is available. This teaches you how to play the ROM-Pack tunes by lighting LEDs above each key, and blinking the light above the key that is to be played next. White notes have red LEDs, while black notes are indicated by green LEDs. Additionally, the PT-82 and PT-87 feature a "Rating" feature, which scores your performance, based on how accurately you played the tune last. This uses the LEDs above the keys as a kind of graph - the further right the LED that lights, the higher your score for that performance. Ratings of "Try it again", "Fair", "Good" and "Excellent" are marked on the keyboard, and each rating class is associated with a jingle that plays after the rating is displayed.
Of all the keyboards I own, this is among my favorites. The simple square-wave-based voices with minimal filtering, combined with the simplistic rhythm and accompaniment, perfectly encapsulate everything I love about these old 1980s keyboards. The built-in speaker lets it down a bit, but through external amplification it sounds just gorgeous. "
