Raspberry Pi Pico MIDI Channel Muter

This project uses a Pimoroni RGB Keypad with a Raspberry Pi Pico to create 16 "mute" switches for MIDI, one for each MIDI channel. https://youtu.be/8KiXT91sSk8 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 … Continue reading Raspberry Pi Pico MIDI Channel Muter →

Arduino Analog Keypad Mozzi Synth

Back when I was messing about with LDRs I made the comment that there are many different kinds of sensors you could use to replace potentiometers in a synth. Having now had a play with analog keypads, I thought they'd be a fun thing to try. The conclusion - it works, but I'm still deciding … Continue reading Arduino Analog Keypad Mozzi Synth →

Pico MIDI Keypad Mini Tenori-On

I'd love to have a proper Tenori-on. It is a pretty unique kind of electronic instrument with a 16x16 grid of buttons that allows you to draw patterns that are then played in sequence. But as that is very unlikely to ever happen, I have to be content with making my own! Here is a … Continue reading Pico MIDI Keypad Mini Tenori-On →

Analog Keypad Tone Controller

I've picked up a couple of cheap 3x4 keypads so thought I'd look at its potential as a music controller. https://youtu.be/C1n5NBVvfLg 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 Analog Keypad Tone Controller →

Vintage Phone USB MIDI Controller

This is the USB MIDI controller version of the Vintage Phone MIDI Controller. As the USB MIDI support is much easier in CircuitPython than MicroPython, this is also a version of the keypad controller code for CircuitPython too. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for … Continue reading Vintage Phone USB MIDI Controller →

Vintage Phone MIDI Controller

I happened across a pretty dirty Doro x20 push-button phone in some very 70s colours in my garage as part of a clear out and thought it might make a fun MIDI controller. My first experiment uses a Raspberry Pi Pico (in "sawn-off" mode - see later!). In this follow-up post, I turn the phone … Continue reading Vintage Phone MIDI Controller →

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 →

Keyboard MIDI Matrix Decode

Following on from my Keyboard Matrix Decode I've now added MIDI out! So I have a full sized MIDI controller keyboard for the cost of a cheap Arduino Nano clone and a couple of passive components! https://youtu.be/kqcfxiKIzi4 Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for … Continue reading Keyboard MIDI Matrix Decode →

Keyboard Matrix Decode

I found an old keyboard, a "KSP970" which is a sub £20 keyboard with full size (non touch sensitive) keys, that was being thrown out as battery acid had corroded away most of the circuit board inside, but the keyboard itself was still intact so I thought it would make an interesting project to attempt … Continue reading Keyboard Matrix Decode →
