MT32 Clumsy MIDI Simple MIDI Filter

My MT32 Clumsy MIDI Program Changer and Filter was a little disappointing, in that it didn't seem to be able to keep up with the MIDI stream for my Lo-Fi Orchestra, so I thought I'd try for a simpler version using the 5V/16MHz Arduino Pro Mini without the extras for selecting the MT32Pi voice to use. … Continue reading MT32 Clumsy MIDI Simple MIDI Filter →

Lo-Fi Orchestra – Saturn from The Planets

Inspired by the legendary Tomita, the Lo-Fi Orchestra presents Saturn from Gustav Holst's Planets Suite. This is using the same Lo-Fi Orchestra setup as Jupiter, which is detailed in full here. There is a lot of dynamic nuance in the original, but unfortunately the Lo-Fi Orchestra doesn't really do nuance, it is mostly "on" or … Continue reading Lo-Fi Orchestra – Saturn from The Planets →

Universal Microcontroller MIDI Module

It's been a while since I built a MIDI module... actually, I need the "raw electronics" from a MIDI In/Out interface for a project I'm planning, and wanted it to support either 3.3V or 5V microcontrollers, so this little project was the result. While I was at it, I thought I'd add in a low-pass … Continue reading Universal Microcontroller MIDI Module →

Toy Keyboard Matrix Decode with the Pi Pico

I'm always on the look out for discarded music keyboards that I might be able to do something with, so when I came across this thrown out in the street I claimed it to take a look. This shows how I used a Raspberry Pi Pico to decode the keyboard part and turn it into … Continue reading Toy Keyboard Matrix Decode with the Pi Pico →

MT32 Clumsy MIDI Program Changer and Filter

Having used my MT32-Pi (in fluidsynth mode) with an updated Arduino MIDI Filter in the Lo-Fi Orchestra – Jupiter from The Planets I decided to combine them with my Arduino MT-32 Program Changer try to create an add-on board for my Clumsy MIDI interface to allow a self-contained unit that: Can set the patch number (voice) for the MT-32 … Continue reading MT32 Clumsy MIDI Program Changer and Filter →

Lo-Fi Orchestra – Jupiter from The Planets

Inspired by the legendary Tomita, the Lo-Fi Orchestra presents Jupiter from Gustav Holst's Planets Suite. There are 11 Arduino Nanos, 6 Arduino Unos, 1 Arduino Pro Mini, 1 Adafruit Feather 32u4, and a Raspberry Pi using the following projects from this site: On brass: Arduino Multi MIDI Tone Module. On high wind: Arduino MIDI R2R Digital Audio … Continue reading Lo-Fi Orchestra – Jupiter from The Planets →

Arduino MIDI Filter – Revisited

This is a minor update to my Arduino MIDI Filter to allow it initialise patches as well as filter MIDI if required. 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 are the key Arduino tutorials for the main … Continue reading Arduino MIDI Filter – Revisited →

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 →

Lo-Fi Orchestra – Sky Toccata

The Lo-Fi Orchestra presents the Sky interpretation of Bach's Toccata in D minor (BWV595), first released on their Sky 2 album back in 1980. The famous opening features the newly configured "triangle wave" of the Arduino Multi-pot Mozzi FM Synthesis. As you might expect there is also a strong presence from the guitar and bass from … Continue reading Lo-Fi Orchestra – Sky Toccata →

Lo-Fi Orchestra – March to the Scaffold

The Lo-Fi Orchestra presents The March to the Scaffold. This is the fourth movement from the Symphony Fantastique by Hector Berlioz, describing a dream whereby an artist thinks they have killed their lover and are now being marched to their execution! The Arduino MIDI Relay Servo Drumkit provide the military accompaniment, to the Arduino Multi MIDI Tone … Continue reading Lo-Fi Orchestra – March to the Scaffold →
