  3. Folks, please pardon my ignorance, but what exactly is a MIDISpeak, what is it for, and why is it important to electronic musicians and hackers?

    Chances are, I have overlooked something painfully obvious here, but I have never heard of this particular gadget before.


    • Hi Daniel,

      The MIDISpeak is a MIDI retrofit for the Speak & Spell and similar toys. It allows you to trigger sounds in the Speak & Spell using any MIDI controller.
