For the course MCT4045 - Interactive Music Systems, I built a wearable drumset. The wearable drumset consists of a piezo-element placed on one hand, a force-sensing resistor on the other and a accelerometer on the fot. These sensors are then used to trigger one file each. In my case I used a kick drum sound for the foot, snare drum sound for the piezo element and a hi hat sound for the FSR. Then when these sensors are triggered, the sound that are mapped to the sensor will be played. For example if I stump my foot, the kick drum sound will be played.
The three sensors are connected to Bela, with processing and playback of audio files in C++. The playback of audio files will be played from the analog audio output of the Bela. Below you can see a picture of the Bela and the connected sensors. On top left you see the force-sensing resistor, top right is the piezo element and bottom right are the accelerometer.
