Success Cases

Could you supply a little more detail on what the right hand screen does

Right screen is a totally different device. It is a capacity screen with esp32 microchip that I programmed using arduino libraries to monitor fatar 13 note pedal matrix, render screen using lvgl library and send midi notes using midi protocol that I implemented using arduino serial library. It is not necessary because fatar pedal comes with primitive midi controller that can be plugged to zynthian on the left. I thought that it would be clever to implement chord playing too that can be set with root note and a harmony mode but then I realise that you can put midi chord fx in front of zynthian instrument that can do the same.

I talked more about this pedal on this post.

Pedal Board from Aeolus discussion

I use zynthian only inside my bass pedal while playing guitar. I am very interested in organ pedal sounds. Would pedal only patch be required or it does not matter and I will be able to use organ pedal sounds by selecting some other patches? [IMG_1616]

Also zynthian on the left is using zynthian minimalistic PCB that add midi, 4 encoders and audio out to raspberry pi. I explained more about it on this post:

Encoders directly to the GPIO of the Pi 4?

You need to avoid serial pins for midi, i2s pins and audio protocol and their in and out data pins (audio in data pin is only occupied if audio card has adc capability - only few have it). If you use dsi screen you do not need to worry about pins occupied by screen. Do not forget that you will need debouncing 100n capacitor for each encoder’s switch and 10n debouncing capacitor for each encoder A and B lines (two per encoder). I have design before minimalistic zynthian rpi HUT that provides …
