Apple Pen Utilized as Synthesizer Fat Size and 3D Image Editing Control

As the Apple Pen was created like a drawing device for innovative experts, MacRumors audience Simon Gladman has generated three Swift demo apps that display the item getting used for three unusual reasons — like a fat size, managed synthesizer and 3D control for image-editing.


PencilScale, centered on Goodmanis Plum-O-Meter, is definitely an experimental app that runs on the homemade funnel to turn the Apple Pen into an electric size that’s highly-sensitive, although not extremely precise.

The test functions by subtracting the contactis pressure from the foundation fat, that will be “established whilst the present touch pressure once the ‘zero’ switch is pushed,” and spreading it by 140 to get a really tough weight in grams.


PencilSynth is definitely a AudioKit-driven synthesizer that may be managed from the Apple Pen based on its alignment and placement.

  • Apple Penis outside placement about the display regulates regularity
  • Apple Penis straight placement about the display regulates the modulating multiplier
  • Apple Penis elevation position regulates the provider multiplier
  • Apple Penis azimuth position regulates the modulation catalog


PencilController is definitely a fresh image-processing app that employs the Apple Pen like a control for that good environment of guidelines on Primary Image filters.

The demonstration has three picture selection settings:

  • Color/Saturation – Apple Penis azimuth position handles hue and its elevation position regulates the saturation
  • Lighting/Distinction – Apple Penis elevation position along Northern/South regulates distinction and the position along West/East regulates brightness
  • Gamma/Publicity – Apple Penis elevation position along Northern/South regulates publicity and the position along West/East regulates gamma

Gladman describes that “the app uses routine was loaded by a spring, therefore the person must hold among the mode secrets within the bottom-left of the display down in which to stay the style that is selection.”

The source code for several three tasks can be obtained on GitHub.
