(Updated 22.Aug.2021) I made FR4 pcb panel using Cherry MX mechanical keyswitch! It’s so comfortable.
Make Noise Pressure Points and René (current) have very useful touch interfaces. But René (Classic) sometimes failed to recognize touch.
It’s obvious that the best way is using René (current). But I decided to modify my own René (Classic) replacing with tactile switch.
Result
It works fine!
- Pros: Operation works perfect. It also generates acoustic percussive sound of tactile switch and tactile feedback.
- Cons: Finger slide technic can’t do. Very fast trill touch technic is difficult.

Circuit
- connect one side of each switches to pin 1–18 (one by one).
- connect the other side of each switches to pin 19.
Another imaginary ideas
- Breakout panel with Arcade buttons (like Midi Fighter).
- Trackpad with MCU panel (like kaoss pad).
