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 →

Arduino Light Mozzi Generator – Part 2

I've spent a fair bit of time playing with the Control_Echo_Theremin example and finally committed it to stripboard. I was originally aiming for a fully self-contained module, speaker and all, but after a day or so trying to find a simple amplifier that works well with a PWM output, I've put that on hold for … Continue reading Arduino Light Mozzi Generator – Part 2 →

Auduino Light Controller

For the last in this series about using Light Dependent Resistors (for now), I'm having another look at the Auduino Granular Synthesis project. These are the key Arduino tutorials for the main concepts used in this project: Arduino Analog Input Auduino Granular Synthesis If you are new to Arduino, see the Getting Started pages. Parts list Arduino … Continue reading Auduino Light Controller →

Arduino Light Mozzi Generator

Now we have our simple LDR circuit there are a number of other experiments we can try. This page suggests a few more ideas based on the examples provided with the Mozzi synthesis library. In part 2 I build this up on stripboard. Tutorials used in this project: Sounds from Sensors with Mozzi Mozzi Library … Continue reading Arduino Light Mozzi Generator →

Arduino Light Tone Generator

Having played a little with my 556 Timer Light Theremin I thought it time to get an LDR attached to an Arduino. A common extension to the Arduino Tone Generator is to replace the potentiometer with a light dependent resistor (LDR) to give a fun instrument that responds to light in a way similar to how a … Continue reading Arduino Light Tone Generator →

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 →

Auduino Granular Synthesis – Part 2

After having an initial look at the Auduino project, I was very interested in finding out more about how it worked, but the Internet seems somewhat mute on the subject and I've not found any information from the original author. If you know of such a link, be sure to let me know (at the … Continue reading Auduino Granular Synthesis – Part 2 →

Auduino Granular Synthesis

The Auduino project (not a typo - AUduino as in "audio arduino") by Peter Knight has been around a while (over 10 years!) and is many people's introduction to digital synthesis on the Arduino, so inspired by reading about someone else's recent build I thought it was time to take a look myself. In part … Continue reading Auduino Granular Synthesis →

Ready-Made MIDI Modules

This page collects together any "ready to go" MIDI interfaces that I've used for any of my projects. It will be updated as I discover and try new ones. If you want to build your own, there are plenty of ideas on the Arduino MIDI Interfaces page. Note: I have no affiliation or interest in … Continue reading Ready-Made MIDI Modules →
