Display screen piano keys - Help!

Hello everyone!

Long time lurker, first time poster.

I have been making my first patch (currently titled Diatonic, Anti-Gravity Bouncing Ball… but perhaps I needs something snappier) and I am really happy with the audio.

I have been experimenting with different interface options and happy with knobs, aux etc but the one thing that I am struggling with is the screen. I would like to experiment with the piano display (like in Punchy, Pow Pow’s Polybeats etc. I particulary like the one octave size one for maximum clarity.)

However upon opening up the above patches for reference my brain has instantly melted. Is there a resource for explaining how the piano display works? Or a patch with a simple implementation that is easily followed? Or can someone explain it to me?

Sorry if this has been asked before, couldnt find anything on the forum or otherwise about this…

Thanks in advance!

That’s what I use as reference when doing screen stuff

This is exactly what I was looking for, thank you!
