Hi everyone.
I’m happy to share with the first version of my MIDI sequencer / looper.
It’s a 4 channels monophonic MIDI sequencer / looper, with up to 128 steps, made with an Arduino Nano. And I use it a lot for building music from scratch.
I did a small video about it, how it works … etc …
I put the design and all the explanations on my website.

I’m working on a second version now, with an OLED display, a SD card reader for saving/loading sequences … and without pull-down resistors (something I learned recently, thanks to the nice people from this incredible forum).
