Arduino MIDI Multi MUX Step Sequencer

This applies the same extension from the Arduino MIDI Multi MUX Controller to the Arduino MIDI Mux Step Sequencer showing how it could be expanded to support 32 potentiometers or more in a MIDI step sequencer. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage … Continue reading Arduino MIDI Multi MUX Step Sequencer →

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 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 →

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 →

Arduino MIDI LED Step Sequencer with MCP3008

Having now experimented with an SPI eight-way analog to digital converter in the shape of the MCP3008, I wanted to build a step sequencer where the type of analog input was configurable. This project allows you to choose between the following options for controller the steps of the sequencer: The native analog inputs on the … Continue reading Arduino MIDI LED Step Sequencer with MCP3008 →

JC Pro Macro (V2) MIDI Controller

I was exchanging some messages with Jeremy Cook on Twitter about Arduino tones on Leonardo compatible boards (i.e. those driven by the ATmega32U4) and that lead to a conversation about his latest crowd-funding effort for a Pro Micro-based "Macro" keypad and rotary encoder. One thing led to another and he very kindly sent me one … Continue reading JC Pro Macro (V2) MIDI Controller →

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 →
