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 →

Trinket FM Synthesis with Mozzi

Having played around a little with the Adafruit Trinket M0 I'm now starting to spend some time learning about the SAMD21 processor on board as part of an investigation into 32-bit ARM processors and their possibilities for synthesis. In a follow-up post I add MIDI host support via the built-in USB port. In a further … Continue reading Trinket FM Synthesis with Mozzi →

DIY MIDI Interfaces

This page is a mixture of beginner and advanced, DIY options covering MIDI in (receive), MIDI out (send), and USBMIDI to MIDI conversion for non-Arduino like microcontrollers. Here are some other pages of interest: Ready-Made MIDI Modules - a range of modules for "ready to go" MIDI IN and OUT for both 5V and 3V … Continue reading DIY MIDI Interfaces →

Pi Pico PIO Poly Tone Step Sequencer – Part 2

In this project I've added some basic IO to the Pi Pico PIO Poly Tone Step Sequencer. https://youtu.be/a5Mkd0wnbzs 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 tutorials for the main concepts used in this project: MIDI, MicroPython … Continue reading Pi Pico PIO Poly Tone Step Sequencer – Part 2 →

Pi Pico PIO Poly Tone Step Sequencer

In the next part of my messing around with the Raspberry Pi Pico PIO polyphonic tones, I've paired it up with my Pi Pico Keypad MIDI Step Sequencer using my Pimoroni RGB Keypad. In part 2 I add some MIDI controllers. https://youtu.be/JJSOUhSP038 Warning! I strongly recommend using old or second hand equipment for your experiments. I … Continue reading Pi Pico PIO Poly Tone Step Sequencer →

Pi Pico PIO Poly Tone MIDI “Pack”

This is a simple "pack" design for the Pi Pico PIO Poly Tone Keyboard providing 8-note tone-style polyphony with MIDI in functionality. 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 … Continue reading Pi Pico PIO Poly Tone MIDI “Pack” →

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 →

Arduino Top Octave Generator – Counter Experiments – Part 2

This is an incomplete experiment, but I wanted to test the principles from Arduino Top Octave Generator and Arduino Top Octave Generator – Counter Experiments in practice a little more. You may recall the basic idea here is to generate 12 tones using an Arduino and then use binary counters to divide them by 2 several … Continue reading Arduino Top Octave Generator – Counter Experiments – Part 2 →
