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 →

Arduino Mozzi FM Synthesis with MCP3008

I'm always on the look out for new ways of building control modules for my Arduino synthesizers, so when I discovered the MCP3008 SPI 8-channel analog to digital converter, I thought I'd give it a go with my Arduino Multi-pot Mozzi FM Synthesis. https://youtu.be/A5if3Y4u8aM Warning! I strongly recommend using old or second hand equipment for your … Continue reading Arduino Mozzi FM Synthesis with MCP3008 →

JC Pro Macro (V2) MIDI Controller – Part 2

Following on from the JC Pro Macro (V2) MIDI Controller as a step sequencer, this project shows how it can be used as a generic MIDI controller. https://youtu.be/LjU9QdAnlJg 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 previous projects … Continue reading JC Pro Macro (V2) MIDI Controller – Part 2 →

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 →

“Bare Metal” Raspberry Pi Synth

The Raspberry Pi is an "SBC" - a single board computer, whilst the Arduino (and the Raspberry Pi Pico for that matter) is a microcontroller. Simplistically a single board computer is, well, what most people would think of when they think about a computer - a board (with or without a case!) that you plug … Continue reading “Bare Metal” Raspberry Pi Synth →

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 →

Arduino MIDI Rotary Encoder Controller

I've finally gotten around to having a play with rotary encoders. It has been on my "to do" list for a while, so I thought I'd start with a rotary encoder version of my Arduino MIDI Button Controller which can select a voice and send the corresponding Program Change message out over MIDI. https://youtu.be/uxT_RQs1MXM Warning! I strongly … Continue reading Arduino MIDI Rotary Encoder Controller →
