I recently saw a post on the VI-Control forum where an AudioSwift user shows his custom design skin for the Magic Trackpad. It helps him with positioning the fingers through the different controller modes in AudioSwift. The design divides the trackpad into equal parts; it uses colors and line weights to visually differentiate the zones. He produced the skin using the site SlickWraps, where you can upload your custom design and they send it to you for about $20.
I like it because it covers the different types of controllers: 4 sliders, 16 trigger pads, many XY pad configurations and even the jog wheel in the Mixer Mode. Brian Norris (a.k.a MichiganMan on VI-Control) designed it, and he kindly shared the templates with me. You can download the zip file for free in the link below and tweak them to your taste. They are in PSD, AFPHOTO, TIFF, JPG and PDF formats.
SlickWraps only makes skins for Magic Trackpads generation 2 and 3, not the 1. There are other similar sites that do the same thing. I found this one DecalGirl that makes skins for generation 1.
I’m not affiliated with SlickWraps or DecalGirl, but maybe this is something you would be interested to use with AudioSwift. If you make a custom trackpad skin for AudioSwift, it would be great to see it and maybe you can also share it with the community. Tag me on either my Instagram or X (Twitter) profiles.
