Via the Little-Scale blog is this Teensy-based project which features 12 gate outputs that are set using note messages over USB MIDI.
Each note in the scale (C, C#, D, D# etc) corresponds to a gate output labelled G1 – G12, and will set high from a note on message and low from a note off message.
If a USB MIDI clock sync is sent, Gate 12 will output a short trigger upon sequencer START or CONTINUE. Gate 11 will output a sync signal at a rate of 12PPQN. Gate 10 will output a sync signal at a rate of 16th notes. Gate 9 will output a sync signal at a rate of 8th notes.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
