PICO MIDI CheeseBox Version 3

I’ve spent the last day or so writing code. Which has been great fun. The focus of all the effort has been my PICO MIDI Cheesebox which has had something of a makeover. I’ve now got a PCB based version which has an OLED screen in the middle. I’ve added messaging so that you see what you are doing when you press a button. I’ve also added full setting save and restore so that you can create a pattern and store it in the device. And this afternoon I spent some time making an arpeggiator. Such fun. I’ll put it on on GitHub once it works.
