I'm a guitar player, not a Keyboard player, but I bought this at the same time as my Model 15 to see what difference polyphony would make to what I wanted to get from synths. Itch scratched, so I ordered a P-800. Back in the 70s, someone created the 'Stylophone' who i understand are still around. Half a century later we have cigarette packet sized polyphony? Yes please. My only reasons for marking this synth down are the fiddly controls, tiny screen, and lack of reverb. The first two points are unavoidable in a package this size, but there must be room in a microchip for some reverb, surely? But for the price of three packs of cigarettes, endless fun. Make sure all of your kids get one for Christmas.
