For this week’s project, Nick and I decided to create a cover for one of our favourite songs, “Shooting Stars” by the prominent Disco/Tech group Bag Raiders. Our project was divided into two parts, the beat (using Servos) and the melody (using Tone).
In total, we had three percussion-like instruments. The first, being a cork attached to a wooden stick, banging on a piece of wood, functioned as the underlying drum that would provide the 1/4 beat. Next, we had two metal rods attached to two different Servos hit glass cups to create clinking sounds that would harmonise with the Tone produced by the buzzers.
Our Tone had 4 buttons, namely four sounds (E-flat, E,B,A-flat). Each button would make the sound designated for 300 milliseconds, and with code we just had to make sure that we were using F-sharp, for example, the different name of A-flat since those weren’t registered in the library.
So below is the result of what we have created, since midnight yesterday when we first joined forces. Hence the name “Midnight Band”. Enjoy!
