Arduino MIDI Telephone Ringer

One thing I love about those vintage rotary telephones is the characteristic ring. But making them do that outside of being plugged into the PSTN isn't easy. But I wanted to see if I could make it work over MIDI, so this is my approach. In part 2 I add some BT style sockets and … Continue reading Arduino MIDI Telephone Ringer →

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 Multi MIDI Merge

I've already had a basic MIDI merge project, combining USB MIDI and serial MIDI into a single serial MIDI out (see Arduino USB MIDI Merge). This project takes that forward to provide the options for a whole range of MIDI IN interfaces merging to a single MIDI OUT. In Part 2 I develop the code … Continue reading Arduino Multi MIDI Merge →

Arduino MIDI Rotary Encoder Multi-Track Step Sequencer

Now I have the option for multiple colours for my step sequencer displays, I thought it might be interesting to start experimenting with a "multi-track" step sequencer. https://youtu.be/oQc1IVoJLeQ Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key … Continue reading Arduino MIDI Rotary Encoder Multi-Track Step Sequencer →

Arduino MIDI Rotary Encoder Step Sequencer – Part 3

I am continuing my experiments with different ways of visualising a step sequencer and this comes from from a suggestion by Twitter user @AxWax - using a NeoPixel ring. https://youtu.be/u4WNbgCWvds Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are … Continue reading Arduino MIDI Rotary Encoder Step Sequencer – Part 3 →

Arduino MIDI Rotary Encoder Step Sequencer – Part 2

In my last post, I mentioned other display options for my rotary encoder step sequencer. To be honest, I wanted an excuse to use some "LED bars" with a rotary encoder, so this post is more by way of an excuse to play rather than a serious option, but in reality it actually works quite … Continue reading Arduino MIDI Rotary Encoder Step Sequencer – Part 2 →

Arduino MIDI Rotary Encoder Step Sequencer

I'm thinking about other applications for a rotary encoder and one thought was to support a multi-step, step sequencer with just a single knob, so this takes the Arduino MIDI Step Sequencer and recodes it to use the rotary encoder and 7 segment display described in Arduino MIDI Rotary Encoder Controller. Here are some links to … Continue reading Arduino MIDI Rotary Encoder Step Sequencer →
