MiniDexed Raspberry Pi IO Board – Part 2

This is the set of build notes for the smaller of my MiniDexed Raspberry Pi IO Boards. Update: There is a newer version of this board: MiniDexed Raspberry Pi IO Board V2 Design. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These … Continue reading MiniDexed Raspberry Pi IO Board – Part 2 →

MiniDexed Raspberry Pi IO Board

I've been toying with the idea of some kind of IO board for my MiniDexed experiments for use with a Raspberry Pi. I initially wanted something fully self-contained - i.e. just pop it on a Raspberry Pi and you're good to go. But then it was pointed out that having all the IO connections on … Continue reading MiniDexed Raspberry Pi IO Board →

Zynthian Revisited – Part 2

Having prototyped the idea of a hardware user interface with my Zynthian in Zynthian Revisited this posts develops a DIY IO board for use with a Raspberry Pi to make connecting everything a little neater. If I like it I might see if I can turn it into a custom PCB. Eventually I'd like a … Continue reading Zynthian Revisited – Part 2 →

Zynthian Revisited

After having a quick play with Zynthian just over a year ago, I've always had it in the back of my mind to make a "proper" Zynthian box with its own interface and controls. This is the first part of that project, hooking it up to a touchscreen and some rotary encoders. In Part 2 … Continue reading Zynthian Revisited →

“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 →

“Bare Metal” Raspberry Pi Synth – Part 4

I wanted to revisit my "Bare Metal" Raspberry Pi Synth as I only really just got started. But having left it some five months since last having a look, I had a bit of updating to do! But then this post describes how I built and tried out the "minisynth" application from Rene Stange (rsta2) … Continue reading “Bare Metal” Raspberry Pi Synth – Part 4 →

Raspberry Pi v1 Model B Synth Board

If you've been following along, you'll know I've been playing around with an original Raspberry Pi v1 model B as the engine for some digital sound synthesis. This is a slight project tangent to build an analog IO and MIDI add-on board. Note that this does not conform to any standard for Raspberry Pi add-ons … Continue reading Raspberry Pi v1 Model B Synth Board →

“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 →
