Hi, I'm looking for suggestions to do this simply. Thanks for any tips.
I want to build a metronome that has a ring of 16 LEDs, each representing a 1/16th note. Together they would constitute one measure in 4:4 time, and the LEDs would loop around the circle repeatedly. Looks like this is an 'LED chaser' type application, and I've read the posts about chasing LED's to arbitrary counts using the CMOS 4017, with special tricks to sequence which 4017 is enabled to light LED's.
I'm wondering if there's an opportunity to do this more simply, given that I have 16 LEDs? Kind of a digital magic number. Doesn't need to use the 4017.
Thanks for any suggestions.

In case you're interested in the application, I'll mention that not all the LEDs will have the same color. The upbeat and downbeat LEDs will have unique colors, and the quarter note LEDs will share a different color (less bright), and the rest of the 1/16th note LEDs will have another color, even less bright. I'm a drumming student and so far I'm working in only 4:4 time and this project will help me coordinate fills with the beat. I'll drive it from my function generator so I can easily change the beats per minute. I may add a BPM indicator once I get the metronome working. And maybe a bar counter that counts to 12 for 12-bar blues.
