Arduino Euclidean LED drivers

[CubuSynth]

Hi,
I made a eurorack PCB to the Arduino Euclidean code.
The first channel is working fine, the Gate out and the controls work on all, but the LEDs on channel 2,3 and 4 are have a strange behaviour.. Hope you can see in the video.
I can't find a solution myself, I couldn't spot any difference to your schematics or code... Maybe something wrong with the LED drivers?

Your help would be very apreciated.
Greetings,
Ruben

Hi Ruben, Nice work! Would love to see the completed module.  This looks to me not like an issue with the led drivers, but with the GPIO expander. It is likely misreading the encoders, and causing weird changes. Have you used the latest version of the firmware? I updated it some 2 weeks ago to make the encoder reading a bit more robust.  Cheers,  Tim

Nice, Thanks for your fast reply!
I just realized that the MCP23017 library wasn't installed properly. It works now!
And thank you for the amazing work on the code!

Glad you got it working, have fun with it!
