Making MIDI Music with my electric piano and iPad

I've played piano for a long time, but only recently discovered that my electric piano has a MIDI port at the back! Using it is a lot of fun: By connecting the piano to my iPad, I can play music through the iPad. This allows me to change instruments, and record and arrange music.

Here's how arrangements looks like in the GarageBand app:

Of course, some instruments (such as oboe or violin) sound bad, but percussion and plucked instruments generally have a good sampling quality.

Here is an example song making use of different keyboards, drumpads, and effects:

Encouraging People to Be More Careful in Situations With High Infection Risk

2022-03-21 · 18 minute read · university stuff

As you might have noticed, we are currently in a pandemic. Luckily, there are several steps you can take to protect yourself and others: You can get vaccinated, wear a mask, avoid large groups of people, regularly ventilate when being indoors with others, etc. Some of these measures are easier to follow than others. Getting vaccinated is a one-off action, but remembering to open the window every few minutes is a lot harder if you also concentrate on something else, such as working or studying.

In the context of the Sonic Thinking and Neurodesign lectures at our university, I developed an app that continuously evaluates the current infection risk and turns it into music.

The aspirational goal of the project is to enable scenarios like these:

  • You walk into an office that hasn’t been ventilated for a long time. As soon as you step inside, scary music starts to play, like you're in a horror film.

  • Over one hour, your study room gradually fills with people. An alarming tune slowly fades in and gets more dissonant the more people there are.

The Coronoise app takes incidence rate, number of people, and CO₂ levels as inputs and produces sounds.
