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 →

Keyboard MIDI Matrix Decode

Following on from my Keyboard Matrix Decode I've now added MIDI out! So I have a full sized MIDI controller keyboard for the cost of a cheap Arduino Nano clone and a couple of passive components! https://youtu.be/kqcfxiKIzi4 Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for … Continue reading Keyboard MIDI Matrix Decode →

Keyboard Matrix Decode

I found an old keyboard, a "KSP970" which is a sub £20 keyboard with full size (non touch sensitive) keys, that was being thrown out as battery acid had corroded away most of the circuit board inside, but the keyboard itself was still intact so I thought it would make an interesting project to attempt … Continue reading Keyboard Matrix Decode →

Mozzi Output Circuit – Part 2

The simple Mozzi Output Circuit is fine for experimenting but when it comes to combining signals it can really do some damage - I may have trashed the small amp I was using for my experiments - remember my warning - I strongly recommend using an old or second hand keyboard for your MIDI experiments. I … Continue reading Mozzi Output Circuit – Part 2 →

Arduino Multi Mozzi String Synth – Part 2

This projects takes another look at the Arduino Multi Mozzi String Synth and takes a slightly different approach to create a simple four-note polyphonic version of the string synth. To combine the outputs I'm using my Simple Passive Audio Mixer, but that isn't necessarily required. It also relies on (and builds in capability to support) the Arduino … Continue reading Arduino Multi Mozzi String Synth – Part 2 →

Arduino MIDI Filter

I am working on something that might allow several of my projects to come together, but one issue I'm having is the overheads of processing unnecessary MIDI traffic are causing delays in playing for some of the modules. So I thought I'd create a MIDI filter that can be used to see all the traffic … Continue reading Arduino MIDI Filter →

Arduino Multi Mozzi String Synth

This projects takes the Arduino Mozzi String Synth and combines it with the principles from the Arduino Multi MIDI Tone Module – Part 2 to create a simple four-note polyphonic version of the string synth. See Arduino Multi Mozzi String Synth - Part 2 for a development that gives a different option for passing the signal between … Continue reading Arduino Multi Mozzi String Synth →

Mozzi Output Circuit

As part of the Arduino Multi-pot Mozzi FM Synthesis project I put together a simple Mozzi output filter circuit, but it stopped working. After having a bit of a look and poke about it it turns out that the jack socket was faulty, so I ordered a different type of socket and started again. This is … Continue reading Mozzi Output Circuit →

Arduino Multi MIDI Tone Module – Part 2

So, this is a stripboard version of the Arduino Multi MIDI Tone Module. Code and functionality is exactly the same, but I've built a "holder" for four Arduino Nano boards with common power, linked RX and TX, and built-in resistors for speakers. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. … Continue reading Arduino Multi MIDI Tone Module – Part 2 →
