Raspberry Pi v1 Model B Synth Board – Part 2

This is a bespoke PCB design for my Raspberry Pi v1 Model B Synth Board which I was using with my "Bare Metal" Raspberry Pi Synth. Update: Build Guide here: Raspberry Pi v1 Model B Synth Board – Part 3 Warning!

“Bare Metal” Raspberry Pi MiniDexed DX7 – Part 2

This is a continuation of my exploration of MiniDexed.  In part 1 I built a basic breadboard version.  In this part, I've built a DIY "MiniDexed HAT" for a 40-way GPIO Raspberry Pi. Update: There is also now a custom PCB too: MiniDexed Raspberry Pi IO Board. https://youtu.be/7gKDfDWLHzw Warning! I strongly recommend using old or second … Continue reading “Bare Metal” Raspberry Pi MiniDexed DX7 – Part 2 →

“Bare Metal” Raspberry Pi MiniDexed DX7

One project I've had my eye on for some time is Dexed: "Dexed is a multi platform, multi format plugin synth that is closely modeled on the Yamaha DX7". More specifically I noticed there was a version for the Teensy called microDexed that I really wanted to try; that it is also one of the synth … Continue reading “Bare Metal” Raspberry Pi MiniDexed DX7 →

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 →

Raspberry Pi Zero PWM Audio Interface

The Raspberry Pi Zero (I'm talking about V1 here, with no wireless.  At the time of writing, V2 has just been released and I've yet to have a play with that!) has capabilities on par with the first generation "full" Raspberry Pi, so I was keen to try my “Bare Metal” Raspberry Pi Synth on one. … Continue reading Raspberry Pi Zero PWM Audio Interface →

“Bare Metal” Raspberry Pi Synth – Part 3

This project uses an off-the-shelf analog IO board for the Raspberry Pi for my "bare metal" Raspberry Pi v1 (model B) synth. Full index of posts in this series: Part 1: The basics of setting up an environment to build a “bare metal” Raspberry Pi synth application. Part 2: Adding potentiometer controls via an MCP3008 … Continue reading “Bare Metal” Raspberry Pi Synth – Part 3 →

“Bare Metal” Raspberry Pi Synth – Part 2

This post builds on part 1 and starts to add some IO handling code and simple synthesis code to the bare metal Raspberry Pi experiments. Full index of posts in this series: Part 1: The basics of setting up an environment to build a “bare metal” Raspberry Pi synth application. Part 2: Adding potentiometer controls … Continue reading “Bare Metal” Raspberry Pi Synth – Part 2 →
