Logic Noise: Sequencing in Silicon | Hackaday

Logic Noise: Sequencing in Silicon | Hackaday

In this session of Logic Noise, we’ll combine a bunch of the modules we’ve made so far into an autonomous machine noise box. OK, at least we’ll start to sequence some of these sounds. A sequencer is at the heart of any drum box and the centerpiece of any “serious” modular synthesizer. Why? Because you just can’t tweak all those knobs and play notes and dance around at the same time. Or at least we can’t. So you gotta automate. Previously we did it with switches . This time we do it with logic pulses. The 4017 Decade Counter The featured chip this session, the one that gets it all done, is the 4017 Decade Counter. It’s a strange chip, left over from the days when people wanted to count things using IC logic chips instead of just running the input into a microcontroller. But therein lies its charm and usability. At its simplest, you input a clock signal and one of ten differ...
