One slight drawback

A project log for Childs keyboard from the thrift store

Found this neglected keyboard and what it took to get working

One slight drawback for this little keyboard is that it only plays two notes at a time so even a simple three note chord is not possible.

Has anyone else dug into one of these and done a bit of bending to boost the performance?? If so then please chime in :-)

Turn it into a MIDI controller? With some great sounding sound fonts you could surprise people playing it.

That certainly a possible and it sure would surprise and turn some heads ;-)

Maybe even glockenspiel or tubular bells which would give the chime sound you want. 😉

One of the output points actually does have a tubular bell quality to a degree but I need to keep messing with the circuit to raise the frequency of the oscillator a but more. I would like to gain another octave or two. These Led/CdS pairs get a bit fussy after a certain point :-)
