By modern standards, the Quadra is definitely an odd instrument - sort of a combination of several incomplete instruments. But it wasn't considered so odd in it's time, but more of a convenient combination of things under one panel. It's musical personality comes through, seemingly regardless of who's playing it. I'd be happy to take it exactly as it is, in the tradition of having individually unique instruments, rather than generic ones. But what I equally like about the Quadra - and what would keep it from ever being re-issued - is its size. I realize that's easy for a guy in his home music room to say. I just love large instruments, and the Quadra definitely qualifies as large, with it deep and wide panel and long keyboard. There's just something about being bent over a single large synthesizer until the wee hours of the morning, with a single desk lamp, that's full of charm and inspiration.
