Toy Keyboard Tone Piano – Part 4

I'm continuing my series of posts seeing what I can do with a toy keyboard. This post looks at some possible uses of the additional IO pins I freed up in part 3. Part 1 provides all the details for adding an Arduino to the original toy keyboard. Part 2 demonstrates the toy keyboard running … Continue reading Toy Keyboard Tone Piano – Part 4 →

Toy Keyboard Tone Piano – Part 3

This post looks in a little more detail at the keyboard matrix decoding for the toy keyboard to see what is possible with less IO pins. Part 1 provides all the details for adding an Arduino to the original toy keyboard. Part 2 demonstrates the toy keyboard running the Oskitone "Scout" firmware. Warning! I strongly … Continue reading Toy Keyboard Tone Piano – Part 3 →

Toy Keyboard Tone Piano – Part 2

Having now plugged an Arduino into my Toy Keyboard, it is time to start experimenting. The first thing I really wanted to do, was build an Oskitone Scout, but not having a 3D printer or the funds to purchase one, I thought I'd have a go at getting the code to run on my toy … Continue reading Toy Keyboard Tone Piano – Part 2 →

Toy Keyboard Tone Piano

I have a few old toy keyboards kicking around that I've wanted to put an Arduino in, so I finally pulled one apart and had a go. I was "live tweeting" it as I went in this Twitter thread, but thought I'd gather everything so far together into a single post. Further posts in this … Continue reading Toy Keyboard Tone Piano →

The Lo-Fi Orchestra Explainer

I've had a few queries asking what some of the different sections of the Lo-Fi Orchestra are and whilst there is a bit of explanation in the post Introducing the Arduino Lo-Fi Orchestra! it doesn't really break down the projects in an easy to see way. And the orchestra as grown a little since then … Continue reading The Lo-Fi Orchestra Explainer →

Arduino RF24 MIDI Interface – Part 2

Having got the basics of "wireless MIDI" working with my nRF24L01 radios, I wanted to take advantage of the inherent "broadcast" nature of radio and see if I could transmit to a number of receivers at the same time. It turned out to be quite a bit more involved than I was expecting! But I … Continue reading Arduino RF24 MIDI Interface – Part 2 →

Raspberry Pi Pico Multi MIDI Router – Part 2

One thing I've wanted to do since building my Raspberry Pi Pico Multi MIDI Router is build a board a bit like ones DeftAudio produces for the Teensy. This posts describes a DIY version of a 4+2 IN, 4+2 OUT MIDI board for the Raspberry Pi Pico. Warning! I strongly recommend using old or second hand … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 2 →

Arduino RF24 MIDI Interface

One thing I've wanted to try is wireless MIDI. I know you can get MIDI over Bluetooth (there are some rather neat commercial "wireless 5-pin MIDI" adaptors you can buy) and I believe people have used MIDI over Wi-Fi by using ipMIDI ("MIDI over Internet Protocol"). But I've had some cheap nrf24L01 radios for a … Continue reading Arduino RF24 MIDI Interface →

Raspberry Pi Pico MIDI Pedal Keyboard

Quite a number of years ago, I found an old set of organ pedals and MIDI'd them up by the crude method of wiring the pedal switches onto the connectors for the keys of an old Amstrad MIDI keyboard... It was the technology and expertise I had at the time! I stumbled across them a … Continue reading Raspberry Pi Pico MIDI Pedal Keyboard →

Arduino MIDI Channelizer

This project kicked off from a comment in the "Audio/Midi/DMX using Arduino" Facebook group, where someone wanted to know if an Arduino could receive messages on one channel and change the channel number and send them back out. The answer is yes and this is how it could be done. I've based it on my Arduino … Continue reading Arduino MIDI Channelizer →
