I like my MIDI USB keyboard. But unfortunately, it does not have a sustain pedal jack. That is why I built an adapter, which translates the pedal input into MIDI messages. All it took was an Arduino Leonardo (Pro Micro module with ATmega32U4), a breadboard, a 7-segment LED display, two resistors, 2 toothsticks, a 6,3mm mono… Continue reading A piano sustain pedal to MIDI USB adapter

I finally got my very first VR headset this weekend, a Gear VR. Since I needed a new cellphone and liked Samsung’s idea of getting a Gear VR with your Galaxy S7 for free, I decided to go for it.
If you are anything like me, you are curious about the current state and the future of Web Audio. So I asked one of the Web Audio API spec editors, Mozilla’s Paul Adenot, if I could shoot some questions. He said sure, and was so kind to take some time and answer them elaborately. Here are… Continue reading Interview with Paul Adenot, Web Audio Spec Editor
Did you come across digital clipping in web audio apps? I certainly did several times (mostly in my own apps though). This undesired effect occurs when you play several sound sources at the same time, which results in a signal that is louder than the maximum of 0 dBFS.

A song consists of multiple… Continue reading Beatsketch
