SAMD 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 SAMD 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

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”

Arduino Tone Polyphony – Part 5

Ok, I thought I’d done with Arduino Polyphony for the time being, but something else came up today that I wanted to try. My post got a mention on the Hackaday blog and one of the comments has led me to a tweak that helps the tuning a little. https://youtu.be/lEaZhnjikfs Warning! I strongly recommend using old or … Continue reading Arduino Tone Polyphony – Part 5

Pi Pico PIO Poly Tone MIDI Keyboard

Following on from the Pi Pico PIO Poly Tone Keyboard here it is combined with one of the DIY MIDI Interfaces to give an eight note polyphonic MIDI tone module based on the Raspberry Pi Pico. In a follow-up post I develop a "pack" MIDI interface. https://youtu.be/uscUlgJ-NBk Warning! I strongly recommend using old or second hand equipment … Continue reading Pi Pico PIO Poly Tone MIDI Keyboard

Arduino Tone Polyphony – Part 4

In this final (for now) part of my Arduino Tone Polyphony project I'm returning to part 2 which was creating a stand-alone, full 12-note polyphonic tone keyboard with an Arduino Uno and committing it to an Arduino Shield using a proto-shield. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am … Continue reading Arduino Tone Polyphony – Part 4

Arduino Tone Polyphony – Part 3

Having achieved my full 12-note polyphony both over MIDI and using built-in keyboard encoding, the last part of this experiment was to see what range was possible using this method for tones.  This project manages four octaves with 12-note polyphony and tuning that, whilst isn't perfect, isn't too bad either. https://youtu.be/Vf4GcZHLVJQ Warning! I strongly recommend … Continue reading Arduino Tone Polyphony – Part 3
