People building stuff #2

Here’s the Arpeggiator made by Klaus Onnen. Pretty clean! 😀 Thanks to him for sending me these pictures, that is super nice.

Also I discovered this upgrade of my MIDI looper :

Everything is explained in French, but basically this upgrade is 4 notes polyphonic & brings note length recording, which is awesome. This one is made with a Arduino Mega though, because the Nano doesn’t have enough space to store all the notes available.
