" The PAIA Stringz n' Thingz was PAIA's answer to the ARP String Ensemble. Jon Simonton used a top-octave chip with octave dividers to create an affordable polyphonic synthesizer in kit form in the late 70s. While it doesn't have all of the richness of the ARP/Solina string synthesizer, this PAIA unit is in some ways better -- it included a piano(ish) polyphonic sound that was fully mixable with the strings; the violin/viola section could be separated from the cello sound at two different keyboard split points, and probably best of all, the modulation for the string sound (sort of a phaser/flanger effect) was fully controllable by the player, unlike the ARP sound, which was fixed to their idea of a good string sound. There are two outputs, one for the piano sound alone, and one for a piano/string mix, the balance of which is controlled by a pot on the control panel."
