DynamoGenesis posted a pic of his new 10 step sequencer on LiveJournal. The circuit uses a 4017 decade counter IC with some small variations. A 555 clock oscillator is still needed to keep the sequence from going haywire as seen in the video, but I think its kind of cool to have random notes like this. This unit is going to be sold on eBay very soon, we’ll see what it brings.
