ARDUINO MIDI looper / sequencer

DIY STUFF

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).

Awesome!! I already looked at your code some time ago, but it’s great to see a more ready version now! One question: can you sync it to another sequencer? If not, would it be hard to add that?

There’s 3 way for syncing an other sequencer :smiley:

  1. there’s an analog sync output for CV sync clock
  2. there’s also a gate output (it sends a gate a each step, I use it to sync my DIY modular)
  3. there’s MIDI clock signal (start, stop & sync) send trough MIDI

Also it receives MIDI clock signal. So you can build 2 box and connect them together by MIDI and they will be synced.

So, it is MADE to be synced! haha

Very nice! Thanks for sharing this.

I recently found an unused enclosure box which I bought years ago, and I didn’t know what I should make with it, but now I do! :smiley:. I have all the parts I need to build this, so I will start building it very soon.

I also took a look at your code which looked nice and clean :+1:

Looks useful and versatile =) subbed and added to the build list.

Thanks for sharing!

Looks fantastic. I will probably attempt to make something like this at some point when I have some synth voices working to play with and when I have bought a suitable midi controller that has MIDI out.

Hi everyone and thanks for your feedbacks!

I just updated a new version of the circuit as the last one had some issues (I always invert MIDI pins … shame on me).

If anybody started to build it, my sincere apologies. I just have triple checked my blueprint!

It’s not yet functional, but I feel observed…
