    Greetings,

    I am very grateful for the help received so far.

    I am curious if it is possible to connect or play one keyboards sounds to another keyboard.
    Let's take two toy keyboards for example. The circuits are so simple, that the answer must
    be yes. Are there any variations here? Also, what if I wanted to take a toy keyboard and
    hook it's sounds up to a larger inexpensive keyboard? I'm not talking about MIDI. These
    toy keyboards would have pitch resistors which could be replaced with pots. I am thinking
    that one could take the lines that go to the toy keyboard's keyboard and wire them into the
    place where the larger keyboard's keyboard connects to its sound producing circuits.

    Yes that should be possible. Each keyboard will have circuitry to generate the signal, and circuitry to amplify that signal to drive a speaker. You need to take the signal from keyboard #1 and feed it into the amplifier of keyboard #2 by mixing it with the signal generated internally in keyboard #2.

    Start by uploading some photos of the circuit boards from the keyboards.
