First product is (finally!) a 3-axis tablet controller with changeable graphic overlays for various uses. The overlays appear to have buttons/sliders molded into the surface. V nice esp for software use. Output is USB MIDI or good-luck-making-it-work Bluetooth. The control/assignment app only works on Windows 10 and MacOS. Draw your own controller layout if you don’t like what they offer. Can even use it as a typing keyboard.

It doesn’t seem to be heavily promoted or I would have noticed it earlier. So buy one.

(And if you find a USB host converter that will output at least 3 CVs plus a trigger, tell us. The ability to control analog would be a biiig plus. Also beg them to make a bigger control surface.)
