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 →

MCP4725 and Mozzi – Part 2

So, ignoring the delirium that turned out to be MCP4725 and Mozzi this is using the built-in I2C "TwoWire" support in the Mozzi library to talk to the MCP4725 and generate audio. https://youtu.be/xtVi1blvt1c Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive … Continue reading MCP4725 and Mozzi – Part 2 →

MCP4725 Digital to Analog Converter – Part 2

This is a short post showing some of the steps to take the dividing/filter circuit from the MCP4725 Digital to Analog Converter to stripboard or protoboard. If you know how to solder, this is fairly straightforward. If you are not sure, find a good tutorial and then come back and have a go. Recall, both … Continue reading MCP4725 Digital to Analog Converter – Part 2 →

MCP4725 Digital to Analog Converter

After my experiments with Mozzi, one thing I wanted to try was using a dedicated digital to analog converter (DAC), which is something the common Arduinos lack. After some searching I found the MCP4725 which links up to the Arduino using the I2C bus. From the datasheet: "The MCP4725 is a low-power, high accuracy, single … Continue reading MCP4725 Digital to Analog Converter →

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 →

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 Mozzi String Synth

This project uses a specific configuration of the Arduino Mozzi Additive Synthesis project to create a "synth strings" type sound based on detuned sawtooth waves. https://youtu.be/lHMRKDDTzUc 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 tutorials … Continue reading Arduino Mozzi String Synth →

Arduino FM MIDI Synthesis with Mozzi – Part 2

This builds on Arduino FM MIDI Synthesis with Mozzi but bases the code on a different example from the Mozzi library and adds a third potentiometer! Once again, if you are just using the code "as is" this is a beginner project. To get into the detail of the code though takes it into "advanced" territory! … Continue reading Arduino FM MIDI Synthesis with Mozzi – Part 2 →

Arduino FM MIDI Synthesis with Mozzi

This project takes the Mozzi library a bit further and combines the Mozzi example code for potentiometers, FM synthesis and MIDI into one. If you are just using the code "as is" this is a beginner project. To get into the detail of the code though takes it into "advanced" territory! In Part 2 the … Continue reading Arduino FM MIDI Synthesis with Mozzi →
