Minimalist Lo-Fi Minimalism

Whilst I'm not an ardent fan of Philip Glass, (more like an amateur enthusiast), there are certain pieces of his that I do really quite like. The violin concerto goes without saying - some parts of that are wonderful. And I quite like the Low Symphony based on the music of David Bowie. But the … Continue reading Minimalist Lo-Fi Minimalism →

Remotely Analysing a Keyboard Matrix

I've been having a conversation on discord helping someone to try to work out the keyboard matrix of a keyboard in order to eventually use it with a microcontroller. But discord being discord, its fine for chat, but we're both starting to lose track of where we're at in the analysis, so I thought I'd … Continue reading Remotely Analysing a Keyboard Matrix →

Duppa I2C MIDI Controller – Part 1

I've had my eye on Duppa's rather neat looking I2C LED rings and rotary encoders for some time and finally pushed "go" on getting a couple. I want to use them as the basis for a MIDI controller but this post is just my "getting to know them" post. Part 1 - getting to know the … Continue reading Duppa I2C MIDI Controller – Part 1 →
