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 →

MozziByte Output Board

I ordered myself a MozziByte board to make playing around with Mozzi a little simpler and it works really well. This details the updates to the Arduino PWM MIDI Synthesis with Mozzi project required to use the new board. These are the key Arduino tutorials for the main concepts used in this project: Mozzi Synthesis Library … Continue reading MozziByte Output Board →

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 VS1053 Synth – Part 2

I'm planning a use of the VS1053 shield but need to be able to pre-select which instruments to play and which channels to respond to. This revisits the Arduino MIDI VS1053 Synth and adds that functionality. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any … Continue reading Arduino MIDI VS1053 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 MIDI R2R Digital Audio

With all the excitement of experimenting with Mozzi, I never really finished my R2R digital audio series. This final part adds MIDI to the R2R shield I built in Arduino R2R Digital Audio – Part 3. https://youtu.be/i6Y9QiTxTeQ Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for … Continue reading Arduino MIDI R2R Digital Audio →

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 →

Simple Passive Audio Mixer

I have a project coming up where I'm going to want to combine several audio outputs together. This would typically require the use of a mixer and a number of circuits are available to perform a nice mixing function. But I've gone for the cheapest, dirtiest solution possible that fits my requirements. It is just … Continue reading Simple Passive Audio Mixer →
