Pi Pico PIO Poly Tone Step Sequencer – Part 2

In this project I've added some basic IO to the Pi Pico PIO Poly Tone Step Sequencer. https://youtu.be/a5Mkd0wnbzs 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 tutorials for the main concepts used in this project: MIDI, MicroPython … Continue reading Pi Pico PIO Poly Tone Step Sequencer – Part 2 →

Arduino MIDI 7 Segment Controller – Part 2

As mentioned in my previous post, the Arduino MIDI 7 Segment Controller is ripe for turning into a self-contained module. To keep it all relatively small, I opted to build an add-on board for an Arduino Nano. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any … Continue reading Arduino MIDI 7 Segment Controller – Part 2 →

Simple Potentiometer Breakout

I've been using potentiometers quite a bit in recent projects and now have two boards that include options to link out to potentiometers to control boards too, so thought it useful to have another, smaller, breakout to make experimenting easy. Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Simple Potentiometer Breakout →

Arduino MIDI VS1003 Shield – Part 2

Having left a good half of a proto shield free in my Arduino MIDI VS1003 Shield I thought it would be useful to add in some potentiometers, a MIDI link and an optional indicator LED. This documents the build process continuing where the previous project left off. Warning! I strongly recommend using an old or second hand … Continue reading Arduino MIDI VS1003 Shield – Part 2 →

Arduino MIDI Mux Step Sequencer – Part 2

By way of completing this initial look at multiplexing potentiometers, this is how I used a Sparkfun 16 port multiplexer in my Arduino MIDI Step Sequencer. https://youtu.be/MiPyJrPlmVs Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino … Continue reading Arduino MIDI Mux Step Sequencer – Part 2 →

Arduino MIDI Mux Step Sequencer

If you keep using single IO ports of the Arduino for your controls you reach the limits pretty quickly. In terms of analog IO that is six inputs for an Uno and eight for a Nano. The solution is relatively straightforward however, use a multiplexer. This project inserts a 74HC4051 eight port multiplexer into the Arduino … Continue reading Arduino MIDI Mux Step Sequencer →

Arduino MIDI Step Sequencer

This adds MIDI out capability to the Arduino Tone Step Sequencer. Here it is driving a Roland MT-32 paired with the Arduino Light Mozzi Generator – Part 2. https://youtu.be/nOx_mO8V0uY Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! These are the key … Continue reading Arduino MIDI Step Sequencer →

Arduino Tone Step Sequencer

I've been meaning to build a step sequencer for a while. This is device that you can use to repeat a simple sequence of notes over and over and build up interesting patterns. In the next part I'll be adding MIDI out. https://youtu.be/oCHl-sRMuUM These are the key Arduino tutorials for the main concepts used in … Continue reading Arduino Tone Step Sequencer →

556 Timer Light Theremin

I found this "Atari Punk Light Theremin" circuit which uses a 556 timer chip but haven't been able to find out much about it on the Internet ... at least under that name... But I did find quite a lot about the "Atari Punk Console" which appears to have taken on an Internet life of … Continue reading 556 Timer Light Theremin →

Simple Synth IO Shield

I have a range of synthesizer chips and modules and some of those come on shields but I needed a way to hook up some potentiometers in a simple manner for testing and playing around. To date I've build separate modules (some examples here and here). One thing I often find is that music shields … Continue reading Simple Synth IO Shield →
