SAMD51 USB MIDI Multi-Pot Mozzi Synthesis

When I left my Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3 I had the following: Mozzi synthesis on the Trinket M0 board (that uses the SAMD21 Cortex M0+ processor core at 48MHz). Four note polyphony. USB device functionality - it can be controlled via MIDI over USB from a PC. USB host functionality - … Continue reading SAMD51 USB MIDI Multi-Pot Mozzi Synthesis →

Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3

So, I've performed some optimisations for my polyphonic Trinket USB MIDI Multi-Pot Mozzi Synthesis and think this is probably where I'll leave the code for the time being. You can get an idea of what it can do in the video below. https://youtu.be/piz4varsgXg Warning! I strongly recommend using old or second hand equipment for your … Continue reading Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3 →

Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 2

This is a first go at getting polyphony running on my Trinket M0 USB Mozzi synth. It is very much a work in progress though as I've just not managed to get the right balance of the different aspects of the system running together yet. But I thought I'd pause and report what I have … Continue reading Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 2 →

Trinket USB MIDI Multi-Pot Mozzi Synthesis

As I mentioned last time, I wanted to get my Trinket handling USB MIDI (as a MIDI host) so I could plug my Korg minikeys directly into it. This wasn't quite as straight forward as I imagined it would be, but I got there in the end. In part 2 I start to look at … Continue reading Trinket USB MIDI Multi-Pot Mozzi Synthesis →

USB-MIDI to MIDI Revisited

Ever since building my Mini USB-MIDI to MIDI I've wanted something a little more self contained. Most of these projects have been built with 8-bit microcontrollers, but the costs of more powerful microcontrollers is coming down all the time and you can now get very powerful 32-bit ARM based boards for really not very much so … Continue reading USB-MIDI to MIDI Revisited →

USBMIDI to MIDI Shield

I've been using my Korg Minikeys for testing a number of these projects, which usually means breaking out my Mini USB-MIDI to MIDI converter, but that means I need to find jumper wires, power, etc, so I thought it would be interesting to mount the appropriate components onto an Arduino pro-shield to create an entire "USB … Continue reading USBMIDI to MIDI Shield →

WS002 – MIDI In, MIDI Monitors and Effects

This second worksheet looks at projects related to receiving and processing MIDI messages, providing a single list of parts and a suggested "building order". This worksheet links together the following projects: Simple MIDI Monitor Simple MIDI Monitor - part 2 Arduino MIDI Note Monitor Arduino MIDI Channel Monitor Arduino MIDI Tone Module Arduino Multi MIDI … Continue reading WS002 – MIDI In, MIDI Monitors and Effects →

Simple USB-MIDI to MIDI

Having experimented with the Hobbytronics USBMIDI device, I always wanted to see if it was possible to build my own using an Arduino. And it turns out to be a lot simpler than I expected, as least to use the USBMIDI keyboard for MIDI OUT to another device. Warning! I strongly recommend using an old or … Continue reading Simple USB-MIDI to MIDI →

Arduino USB MIDI VS1053 Synth

This project builds on the Arduino MIDI VS1053 Synth but introduces a neat little module from Hobbytronics.co.uk that lets you use a range of USB MIDI controllers with the Arduino. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! These … Continue reading Arduino USB MIDI VS1053 Synth →
