AIY Voice HAT and MiniDexed

Someone asked on the MiniDexed forums if the Google/Raspberry Pi AIY Voice HAT could be used with MiniDexed. This reminded me that I had V1 of the kit tucked away in a corner somewhere, so decided to finally take a look at it! Warning! I strongly recommend using old or second hand equipment for your … Continue reading AIY Voice HAT and MiniDexed →

Arduino Euclidean Gate Sequencer – Part 2

I covered all the theory and main functions of the code for my Arduino Euclidean Gate Sequencer in my previous post. In this one I look a little more at some hardware that hopefully lets me use this to actually control something useful! Part 1 covered all the theory and main functions of the code. Part 2 … Continue reading Arduino Euclidean Gate Sequencer – Part 2 →

Arduino Drum Trigger to MIDI

After playing with my Arduino Euclidean Gate Sequencer I started to think about how to turn that into MIDI. One option, naturally, is to add MIDI to the sequencer itself, but I thought the more versatile approach would be to build a second Arduino that took trigger pulses and turned them into MIDI drum messages. This … Continue reading Arduino Drum Trigger to MIDI →

Arduino Euclidean Gate Sequencer

I've always liked the idea of mathematics, algorithms and their application to music, so a Euclidean Sequencer has been on my list of things "to do" for a while. This is my take on how to build one from an Arduino. This post focuses on the code and algorithms - some more useful hardware will … Continue reading Arduino Euclidean Gate Sequencer →

Proto Pedal PCB Design

One (other) thing I was toying with experimenting with is the whole world of DIY guitar pedals. I don't know much about them but wanted a platform I could use for experimentation. Part 1 - PCB Design and Introduction. Part 2 - PCB Build Guide. Part 3 - Proto Pedal Usage and Application Notes. I … Continue reading Proto Pedal PCB Design →

“Baby8” Discrete Logic MIDI (ish)

I've wanted to create a non-microcontroller, discrete logic MIDI circuit for some time. I thought it would be interesting to have a few chips that could generate a specific sequence of bytes corresponding to a MIDI message. Note: I'm still talking individual chips here, not just gates and definitely not individual transistors, so perhaps "discrete … Continue reading “Baby8” Discrete Logic MIDI (ish) →

Educational DIY Synth Thing meets Korg Volca Modular

When designing my Educational DIY Synth Thing I always had in mind that I might be able to hook it up to my Korg Volca Modular. This post looks at the implications and possibilities. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive … Continue reading Educational DIY Synth Thing meets Korg Volca Modular →
