Duppa I2C MIDI Controller – Part 1

I've had my eye on Duppa's rather neat looking I2C LED rings and rotary encoders for some time and finally pushed "go" on getting a couple. I want to use them as the basis for a MIDI controller but this post is just my "getting to know them" post. Part 1 - getting to know the … Continue reading Duppa I2C MIDI Controller – Part 1 →

EuroRack 6HP Arduino Mozzi Module – Basic VCO

This is the first project based on my EuroRack 6HP Arduino Mozzi Module. It is loosely based on HAGIWO's Arduino Mozzi VCO Module. https://makertube.net/w/hnocMAhYkajd8nX2vwuR2u 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 some previous posts for the main concepts … Continue reading EuroRack 6HP Arduino Mozzi Module – Basic VCO →

Raspberry Pi Pico Synth_Dexed? – Part 3

The story so far... In Part 1 I work out how to build Synth_Dexed using the Pico SDK and get some sounds coming out. In Part 2 I take a detailed look at the performance with a diversion into the workings of the pico_audio library and floating point maths on the pico, on the way. … Continue reading Raspberry Pi Pico Synth_Dexed? – Part 3 →

Raspberry Pi Pico Synth_Dexed?

For a while I've wanted to get Synth_Dexed up and running on a Raspberry Pi Pico. This is the library written by Holger Wirtz for use with the Teensy microcontroller, and the core synth engine used for MiniDexed. This is how I got everything up and running although it is too early to know if this … Continue reading Raspberry Pi Pico Synth_Dexed? →

Arduino OPL FM Drum Machine

I've finally returned to having a look at my Arduino OPL FM Synth. This time I'm taking a look at the drum channels. https://youtu.be/IBDu9h4716U 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 … Continue reading Arduino OPL FM Drum Machine →

Arduino and USB MIDI

I've been dabbling for a while with USB MIDI on an Arduino, but I've never really walked through all the options available or pulled together in a single place all the projects I have, so this post looks at all that in a bit more detail. Warning! I strongly recommend using old or second hand … Continue reading Arduino and USB MIDI →

Multi-Mode MIDI Step Sequencer – CDR Format

When I put together the Multi-Mode MIDI Step Sequencer it was with an eye to creating some kind of "modular" style panel format. This post documents the building of a "CDR format" (CD Rack Format) panel version. Part 1 (this post) details the build and testing of the panel. Part 2 updated and enhanced the Multi-Mode … Continue reading Multi-Mode MIDI Step Sequencer – CDR Format →
