Will be curious to see how many levels of pressure. Wacom Intuos pro claims 2048 levels. Dynamic range is important.
I've spent several thousand hours writing visual synths on top of various Wacom tablets, which feels amazing! Have only had a few hours with Apple Pencil, but feels promising.
Tilt is also very expressive. Imagine a joystick with 5 degrees of freedom. Couple that visual targets on the pad to instantly change contexts.
Wacom tablet also supports multiple stylus's, in which case you have two semantically assignable 5dof joysticks. I don't know if multiple Apple Pencils are supported.
- archagon 11y agoI noticed that pushing down too hard with the Pencil causes distortion in one spot of my iPad's screen, presumably where a chip is just a little too close to the surface. So it's probably not a good idea to press (nearly) as hard as you could a Wacom stylus. As an aside, what kinds of visual synths have you worked on? I just added (basic) Pencil support to my iPad sequencer[1] and it works quite well! (With a few caveats[2]...)

- musesum 11y agoLooks pretty cool. Will check it out. Oddly, I have an App that crashes only on the iPad Pro, so I cannot return the favor. :( Have you posted on stack overflow? I have a question, but that may be a better place to ask. Here's is my app, circa 2005: https://www.youtube.com/watch?v=hXlkzZubHnM https://www.youtube.com/watch?v=hXlkzZubHnM I used to VJ a lot. Here's the app in action at Thump Radio, circa 2001 (for a clear view, goto 0:40 sec): https://www.youtube.com/watch?v=5W1jmovV5SM https://www.youtube.com/watch?v=5W1jmovV5SM EDIT "only"
- archagon 11y agoOh, I see! I didn't realize that "visual synths" were a thing — I thought there was a musical component to it. That's fascinating! Are you planning to release something like that for the iPad Pro? "Have you posted on stack overflow" — do you mean regarding my slow motion issue?
- musesum 11y ago>> "Have you posted on stack overflow" — do you mean regarding my slow motion issue? Yes. Was wondering if you tried capturing UITouches on a nil view to get global coordinates. Just a stab in the dark, since I'm fully occupied on an Apple Watch project. > Are you planning to release something like that for the iPad Pro? Short answer is Yes! I'm starting from the ground up by rewriting the underlying functional ontology, called Tr3, which will be open sourced under MIT license.
- logicallee 11y ago>Imagine a joystick with 5 degrees of freedom. why 5? all six - substituting pressure for z - minus roll?
- tenfingers 11y agoyou have both roll and pitch.
- logicallee 11y agoThe reason I said roll isn't counted is because I meant rolling the pen along the long axis (like the way it would roll off of a table)[1] - that I presume isn't being tracked? (If you hold its orientation and pressure and location of tip constant, but kind of roll it between your fingers, that wouldn't cause a detectable change would it?) Is that what musesum meant though by 5 axes? namely x/y on the screen, pressure on the screen, and 2 of the 3 of pitch, roll, and yaw?....

- musesum 11y agotranslated to cartesian coordinates. position x, y; tilt x, y; and pressure. No yaw, which would be twisting the pencil.
- logicallee 11y agothanks - what you call yaw I called roll, by analogy with the shape of a pencil versus airplane.
- tenfingers 11y agoThere's also twisting (yes, it's a true 5 axis). But you have to buy the more expensive "art pen". See: https://www.wacom.com/en-us/store/pens/art-pen https://www.wacom.com/en-us/store/pens/art-pen Notably, some pens support additional pressure axes (for example, the "brush pen"). These are general-purpose sensors can be mapped freely. I'm not aware though of any pen that supports truly 6 axes, but I suspect it's not a technical limitation. [edit] I actually dislike the art pen because of the way it's handled: it's too fat.
- hderms 11y agoWhat do you mean by writing visual synths? I've never heard those words combined together and I'm curious.
