Arduino “Make Your Uno” Synth – 3 – Adding GPIO

As you might have read, one of the main criticisms I had with the Synth Shield was that it didn't include an obvious way to get access to the unused GPIO pins on the Arduino.  This is a great oversight in my view as the whole point of using Arduino is its hardware interfacing opportunities! … Continue reading Arduino “Make Your Uno” Synth – 3 – Adding GPIO →

Pico Dual-core MIDI Visualisations

I started this project as I had just bought two new toys from The Pi-Hut: Waveshare RGB Full-colour 16x10 LED Matrix Panel Waveshare 4-Digit 8-Segment Display Module My initial thinking was to re-run the Pico Unicorn MIDI Visualiser and the Arduino MIDI 7 Segment Controller with these new devices and a Pico.  But whilst playing around, I … Continue reading Pico Dual-core MIDI Visualisations →

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 →

Universal Synthesizer Panel – Auduino++

One of the reasons for creating my Universal Synthesizer Panel is to port over a range of different microcontroller based synthesizer engines to allow me to play with them without having to worry about building hardware.  In this post I return to my Auduino MIDI Granular Synthesis and add a few more features. https://youtu.be/XZ8dcSQfuus Warning! I strongly … Continue reading Universal Synthesizer Panel – Auduino++ →

Multi-Mode MIDI Step Sequencer – CDR Format – Part 2

This post is the second part of my series to document the building of a "CDR format" (CD Rack Format) panel version of my Multi-Mode MIDI Step Sequencer. Part 1 detailed the build and testing of the panel. This part updates and enhances the Multi-Mode MIDI Step Sequencer code to run on the panel. https://youtu.be/YmQ7j-tDudk … Continue reading Multi-Mode MIDI Step Sequencer – CDR Format – Part 2 →

Multi-Mode MIDI Step Sequencer – CDR Format

When I put together the Multi-Mode MIDI Step Sequencer it was with an eye to creating some kind of "modular" style panel format.  This post documents the building of a "CDR format" (CD Rack Format) panel version. This part details the build and testing of the panel. Part 2 will update and enhance the Multi-Mode MIDI … Continue reading Multi-Mode MIDI Step Sequencer – CDR Format →
