I’m very curious if such a thing is possible, if so how?
I’m currently using Playtronica as a midi controller with objects. However Playtronica requires you to make a closed electrical circuit with your body to generate the sound (one wire touching you, one wire touching the object). This makes it a bit awkward for live sound installations, having to drag an extra wire with me every time I approach an object.
I have a friend that worked with arduino in the past, where she generated sound by touching objects. She has long forgotten how to do this.
example sketch from MIDI library can generate tones without any object. so, if you elaborate some input, you can convert it in midi command (note or control change).
i recommend Sparkfun Pro Micro board aka Arduino Pro Micro.
Capacitive touch sensors can detect touch without touching a ground wire or making a complete circuit. Adafruit sells a cap touch board with holes for gator clips if that is what you are looking for.
Some processors have built-in cap touch sensor inputs and USB MIDI. For example, SAMD21.
Ok, so I have the arduino leonardo connected to the adafruit shield which uses the MPR121. The arduino recognises that the MPR121 is connected, however, I am not sure how to get the MPR121 to work as midi, I installed the midi code as suggested above, but my computer is not recognising arduino as a midi device. What are the next steps?
It seems I have the arduino leonardo recognised in my DAW. However, it is not recognising the MPR121 as the midi messages. I created a new topic for discussion of that distinct subject:
