Nano Audio Experimenter Sheild PCB

This takes the Arduino Nano Mozzi Experimenter Shield PCB and swaps out three of the pots for the optional use of the following: MCP4725 DAC. SSD1306 display. IO links for an analog multiplexer. This is in addition to the remaining three potentiometers, the MIDI interface and the audio filter output. Warning! I strongly recommend using old … Continue reading Nano Audio Experimenter Sheild PCB →

Analog IO Board PCB – Part 2

This is the build guide for the Analog IO Board PCB. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments!

Arduino MIDI Multi MUX Step Sequencer

This applies the same extension from the Arduino MIDI Multi MUX Controller to the Arduino MIDI Mux Step Sequencer showing how it could be expanded to support 32 potentiometers or more in a MIDI step sequencer. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage … Continue reading Arduino MIDI Multi MUX Step Sequencer →

Arduino MIDI Multi MUX Controller

This project revisits my Arduino MIDI Mux Step Sequencer showing how it could be expanded to support 32 potentiometers or more in a MIDI controller. 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 Arduino tutorials for the … Continue reading Arduino MIDI Multi MUX Controller →

Arduino USB MIDI Mux Pot Controller

The other application I wanted for my Arduino USB MIDI Mux Step Sequencer is as a general purpose MIDI controller. In this case with 16 potentiometers mapped to MIDI CC messages. This is building on the following previous projects: Arduino USB MIDI Mux Step Sequencer Arduino and USB MIDI “Bare Metal” Raspberry Pi Synth – Part … Continue reading Arduino USB MIDI Mux Pot Controller →

Arduino USB MIDI Mux Step Sequencer

This post revisits an older project - the Arduino MIDI Mux Step Sequencer. Or more specifically, part 2 of that project that used an off-the-shelf 16-potentiometer shield for an Arduino Uno. Except this time, I've paired it with the "upgrade" to my Arduino Uno to make it USB MIDI compliant. https://youtu.be/amagp7ANns4 Warning! I strongly recommend using … Continue reading Arduino USB MIDI Mux Step Sequencer →

Arduino LDR MIDI Piano

I always meant to go back to my Arduino LDR Pianola and extend it to more notes, but so far haven't quite got there. But this projects uses a multiplexer to link up eight LDRs to an Arduino and use it as a simple "keyboard" MIDI controller. https://youtu.be/Ne6J-a7ACwE Warning! I strongly recommend using old or second … Continue reading Arduino LDR MIDI Piano →

Auduino Slider Waveform Granular Synthesis

Now I have a version of the Auduino that will use a wavetable as the grain for the granular synthesis, I can start some alternative experiments, so first of all I thought I would try to use my slider potentiometers to build the wavetable. https://youtu.be/HABkDbIHvO8 Warning! I strongly recommend using old or second hand equipment … Continue reading Auduino Slider Waveform Granular Synthesis →

Arduino MIDI Slider OLED R2R Waveform Generator

This project moves on a step from my Arduino MIDI Slider R2R Waveform Generator and adds a small 0.96" OLED I2C display. https://youtu.be/MGwdu017e00 Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments!
