Hello, Several years ago already the Tuna knobs arrived on the market. These are knobs made for touchscreens to add a real sense of touch on visual programs such as Lemur. Sadly only rotating knobs are proposed whereas I would like to have linear sliders. However I think it shouldn't be too difficult to take the DIY road with some 3D printing. Basically one needs an electrically conductive cursor/wiper touching the surface and some kind of rail or slider that guides the movement and bond to the screen. Any suggestion on how to design or build such sliders?
Edit: here's a visual representation.

So you want the feel of real faders but the flexibility/ functionality of lemur?
But Didn't see anything like the tuna knobs as faders yet Sorry.
I have a side project I fooled with using BCR2000 controller I was about to throw out, but felt sorry for it, then I found a special manual showing how to program the BCR by midi ports
So I managed to create a callable script that talks same programming lang as Behringers BCR2000 and I guess with a tiny mod to script it would work with the BCF2000 to.
So with that I can now assign different settings for each different tab or interface and once it switch to one of them, lemur will run the script that reprogram all the knobs n buttons to match what the current interface wants it 2 control.
So now my lemur n bcr2000 works as one unit. And Lemur is the midi brain instead of presets.
Then I took next step and Frankensteined my bcr2000, so only the top panel is under the iPad working as a LCD screen for the 8 knobs and rest of BCR2000 is hidden away.

Here's the second iteration.  Colors are just there to help separate the two parts (wiper and guide). The real parts would be totally transparent to see as much possible the screen beneath. The hole in the wiper would be filled with electrically conductive materiel. I haven't found a printable materieal both transparent and conductive yet, otherwise the whole wiper would be made in this material. The remaining question ia on how to tie the slider to the screen. Tuna knobs have suction cups but this wouln't function with linear sliders. As I need a whole row, maybe I could glue the guides together and have surfaces on the sides for this purpose. |

A block of 5 sliders could look like this...  |

That is awesome. Best thing imo is to find a local hackerspace to help you print the faders.
