If I had to guess, the cartridge with the ribbon cable probably did attach to the piano keyboard...but the cartridge that had the DIN was likely a MIDI input cartridge; I'm not a musician or anything like that, and only briefly played with real MIDI stuff in high school (circa 1990-91) - but I seem to recall that everything MIDI back then (and probably still today) used DIN plug cables. So the cart with the ribbon cable was just a basic kind of keyboard interface, but the keyboard wasn't MIDI; but I bet at some point (again, pure guessing) that Speech Systems either did away with the the "raw keyboard" design, and found a keyboard that output MIDI, or they put circuitry inside the raw keyboard to turn it into a MIDI output keyboard, or they just stopped selling the keyboard with the cart, making it optional (if they didn't drop it completely). The latter seems really possible, as it would be more likely that anyone who wanted a MIDI cartridge for the CoCo likely already had a keyboard with MIDI output, or full MIDI (IE, both input and output/pass-thru ports; IIRC, MIDI is a daisy-chain I/O bus?).
