This is the first design I made from scratch on my own. It is a simple idea, but I think the result is awesome. Six 555 timer circuits that flash variable rate LEDs and DIY vactrols trigger the keys on the keyboard. You can get a lot of weird patterns and play the keyboard faster than any person's hands could. I have yet to box it and put on the knobs, label the notes, etc. But functionality is fully there. Let me know what you think!

I had that keyboard as a child, it was my first one!
It's nice to see you butchered it into a musical doohickey and not a noisey ear-destroyer Smile

Nice triggering concept on this! To reduce the chip count, you should be able to get one 40106 to do the same job as the 6 555s - it has 6 oscs so would be ideal. You can also feed the input from an osc into a 4016 to trigger keys and buttons, the DIY vactrols can be saved for controlling pots Smile You would need two 4016 chips as each has 4 gates.
