well if you don't want to hit something drawn to the screen you could use pxl-test

Ok, I got some trouble now, my Digital Potentiometers arrived and i set them to the exact same resistance value as the master channel of my sound mixer, i measured the resistance to make absolutely sure it matches the one of the analog resistor. And when using the digital one there is no sound coming out at all!
the digital pots are MCP42010

The power supply of the controlling unit (arduino + digital potentiometers) and the sound mixer (OP-Amps) is a different one.

Do you store each frame or do you somehow calculate them on-the-fly?

Love the animations!

Ok fixed it now in the dev build, the reason for that bug is rather stupid, lol.
Expect it to be live, soon!

EDIT: AAaaaaand, the fix is live! Thanks for reporting!

Welcome!
I hope Tapatalk can insert peanuts.

Yes, it can, only shows on the webpage, though as tapatalk has its own set of smileys

I like this custom font a lot

what if you use some asm lib for custom fonts?
