Vintage Rotary Phone MIDI Controller – Part 7

Having built my adaptor into a small box, I've gone back to add a mode button so I can include all the different applications into a single sketch. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the rotary … Continue reading Vintage Rotary Phone MIDI Controller – Part 7 →

Arduino Timed Relay

I've an idea for a project that needs to wait for a certain length of time and then trigger a relay. So whilst this isn't a specifically musical post at present, this is the detail of how I got that part of the project ready to go. Warning! I strongly recommend using old or second … Continue reading Arduino Timed Relay →

Arduino Slider Phased Rhythms

There is an interesting video going around social media of someone playing a simple drum beat at 120bpm, 119bpm and 121bpm and you can hear the rhythms going in and out of phase, so I thought it perhaps time to update my Arduino Mux Slider Phased Relays to actually play a rhythm. https://youtu.be/hpoJ7eNfn_8 Warning! I … Continue reading Arduino Slider Phased Rhythms →

Arduino USB MIDI Mux Pot Controller

The other application I wanted for my Arduino USB MIDI Mux Step Sequencer is as a general purpose MIDI controller. In this case with 16 potentiometers mapped to MIDI CC messages. This is building on the following previous projects: Arduino USB MIDI Mux Step Sequencer Arduino and USB MIDI “Bare Metal” Raspberry Pi Synth – Part … Continue reading Arduino USB MIDI Mux Pot Controller →

Arduino USB MIDI Mux Step Sequencer

This post revisits an older project - the Arduino MIDI Mux Step Sequencer. Or more specifically, part 2 of that project that used an off-the-shelf 16-potentiometer shield for an Arduino Uno. Except this time, I've paired it with the "upgrade" to my Arduino Uno to make it USB MIDI compliant. https://youtu.be/amagp7ANns4 Warning! I strongly recommend using … Continue reading Arduino USB MIDI Mux Step Sequencer →

Arduino and USB MIDI

I've been dabbling for a while with USB MIDI on an Arduino, but I've never really walked through all the options available or pulled together in a single place all the projects I have, so this post looks at all that in a bit more detail. Warning! I strongly recommend using old or second hand … Continue reading Arduino and USB MIDI →

“Bare Metal” Raspberry Pi Synth – Part 4

I wanted to revisit my "Bare Metal" Raspberry Pi Synth as I only really just got started. But having left it some five months since last having a look, I had a bit of updating to do! But then this post describes how I built and tried out the "minisynth" application from Rene Stange (rsta2) … Continue reading “Bare Metal” Raspberry Pi Synth – Part 4 →

Vintage Rotary Phone MIDI Controller – Part 6

In this final (for now) post, I'm just tidying up the circuit and using a Pro Mini to embed all the electronics I need into a nice small box. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the … Continue reading Vintage Rotary Phone MIDI Controller – Part 6 →

Pi Day MIDI Sequencer

If you write your dates month first, then 14th March is recognised as Pi day i.e. 3.14.(2022) in this case. I've long had the idea of doing something MIDI or sequencer related to number sequences. I'd like to do something with the Online Encyclopedia of Integer Sequences (OEIS) at some point, but as it is … Continue reading Pi Day MIDI Sequencer →

Vintage Rotary Phone MIDI Controller – Part 5

In this post, I describe how to use my rotary phone as a simple random-note MIDI "sequencer" of sorts. The triggering of the notes is driven from the pulses of the dial. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 … Continue reading Vintage Rotary Phone MIDI Controller – Part 5 →
