Reptilian Feline Posted January 3, 2007 Report Share Posted January 3, 2007 I'm making a chord generator and the scematics call for one 50240, and those are hard to find. I know the top octave divider 50240 can play all the notes at the same time, so it's the perfect tool... but... I need to put together a modern day version that doesn't depend on an obsolete part so here is my idea...I use one IC 555 for each note in a chord, so if I make the cords with 3 notes, I need three 555s. If I choose to make the chords with 4 notes, I will need four instead. If I understand it correctly, I devide the notes by adding resistors in a chain. (At least that what it looks like for the FutureKit 13-tone organ.)Is this possible? What parts do I need? Any suggestions on how to wire it?
