My custom paper (N)overlay (and how to improve it?)

Custom Overlay Designs and DIY Projects

Hello all, for my CataRT performance instrument, I use a quadratic area of the morph without overlay (since the magnets are not strong enough to hold one in place when doing expressive gestures), and two control strips for up to 4 fingers for modulation and other trigger modes. It worked quite well to separate them with a paper overlay (with a little fold in between the two strips):

However, after a year of use, the paper is worn out, producing ghost touches, and starts to tear apart (see below). The advantage of being able to put marks on the paper is actually moot since I’m playing this without looking anyway, so I wonder what better alternatives there would be to separate the 2 strips haptically? Two sticky threads/very thin tape? Should not leave a residue, ever, of course…

Thanks for your insight, cheers! Diemo

I did make a silicone overlay that had some gaps in, so that you could have a few controls on it but also a good sized open area for proper gestures. I don’t have it to hand, but can share photos/STL files for moulds in a bit.

Is it just two large strips on the left? I could do a quick STL for that if you feel like doing some 3d printing/silicone casting with magnets?

Hi @mo-seph, thanks for the offer. The ideal design would just be 2 strips as thin as possible (< 2mm) to separate the 3 touch areas.
I wonder if I coulnd’t just wrap two threads around the morph, and keep them in place with tape on the underside.
Cheers!
