Arduino Direct Digital (Additive) Synthesis

This is actually a collection of previous projects with the code tidied up a little and combined to show a single sketch that can be configured for either PWM, an R2R ladder or the MCP4725 I2C DAC. There isn't really anything here that hasn't been talked about before somewhere, but hopefully this can act as … Continue reading Arduino Direct Digital (Additive) Synthesis →

Arduino Audio Experimenter Shield PCB – Part 2

This is the build guide for my Arduino Audio Experimenter Shield PCB. 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 main concepts used in this project: Arduino PWM Sound Output Arduino R2R Digital … Continue reading Arduino Audio Experimenter Shield PCB – Part 2 →

Arduino Audio Experimenter Shield PCB

I have a number of Arduino projects that allow for some kind of synthesis to be output via a digital to analog conversion process.  This PCB brings three of those methods together into a single shield to support a range of experiments. Warning! I strongly recommend using old or second hand equipment for your experiments.  … Continue reading Arduino Audio Experimenter Shield PCB →

Arduino MIDI R2R Digital Audio – Part 2

My Arduino MIDI R2R Digital Audio has been used, pretty much unchanged, in my Lo-Fi Orchestra performances since my first recording, but I've always had a bit of an irritating "Lo-Fi click" when starting and stopping notes.  But whilst I've tinkered a little, mostly I've just lived with it, but now I'm finally taking a look. … Continue reading Arduino MIDI R2R Digital Audio – Part 2 →

The Complete Lo-Fi Planets

Inspired by the legendary Tomita, the Lo-Fi Orchestra presentation of Gustav Holst's Planets Suite is now complete. The original Lo-Fi Orchestra project started off as an attempt to bring a range of my "Simple DIY Electronic Music Projects" together to "perform" a single piece.  After a number of initial performances, I decided to take the … Continue reading The Complete Lo-Fi Planets →

Lo-Fi Orchestra – Neptune from The Planets

Inspired by the legendary Tomita, the Lo-Fi Orchestra presents the final piece, Neptune, from Gustav Holst's Planets Suite. This features the Adafruit Feather MIDI, Music and LEDs on the celesta, the Arduino MIDI VS1053 Synth as the 'harp', and the Raspberry Pi, Clumsy MIDI and MT32-Pi using the Fluidsynth soundscape as the voices. This has been programmed … Continue reading Lo-Fi Orchestra – Neptune from The Planets →

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! These are the key projects for the main concepts used … Continue reading Arduino MIDI Slider OLED R2R Waveform Generator →

Arduino MIDI Slider R2R Waveform Generator

When I first started looking at using fader/slider potentiometers I always anticipated using it to generate waveforms for my Arduino MIDI R2R Digital Audio board.  But as that is currently part of the Lo-Fi Orchestra, I decided I'd build a new one, hence the diversion into using PWM first whilst I decided exactly what to do. … Continue reading Arduino MIDI Slider R2R Waveform Generator →
