AD9833 MIDI Signal Generator – Part 2

This project builds on the AD9833 MIDI Signal Generator and adds a second signal generator for some simple additive synthesis. https://www.youtube.com/watch?v=32NULaB28QM&feature=youtu.be 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 concepts used … Continue reading AD9833 MIDI Signal Generator – Part 2 →

PC USB to DIN MIDI IN

My PC USB MIDI interface is wired into my LoFi Orchestra at present and I don't have another one, but having already done the hard part of getting the software USB MIDI stack up and running I thought it would be fairly easy to add an actual MIDI DIN plug to create a (one-way - … Continue reading PC USB to DIN MIDI IN →

MCP4725 MIDI Sample Player

This is an update to my MCP4725 Sample Player to have it "playable" over MIDI rather than be triggered via a button. 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 MCP4725 MIDI Sample Player →

MCP4725 Sample Player

This is another chance to get out the MCP4725 digital to analogue converter module. This time I want it to play a sampled sound as a type of "effect" based on a trigger. In the next part, I add MIDI support. https://youtu.be/LtqQGB5PInM These are the key Arduino tutorials for the main concepts used in this … Continue reading MCP4725 Sample Player →

PC USB to Arduino Serial MIDI – Part 2

Having built a stand-alone PC USB to Arduino Serial MIDI link, I thought it might also be useful to have a shield that allows a direct PC USB link to the Arduino too. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to … Continue reading PC USB to Arduino Serial MIDI – Part 2 →

PC USB to Arduino Serial MIDI

Whenever I've needed to get a computer to drive my MIDI setup I've wheeled out my Roland UM-ONE PC USB MIDI interface which gives my laptop a MIDI IN and OUT DIN plug. But if I want to get my PC to drive the Arduinos I need to then plug the UM-ONE into one of … Continue reading PC USB to Arduino Serial MIDI →

TFT MIDI Display – Part 3

This display is inspired by the sound and light show at the end of Close Encounters of the Third Kind. It uses the TFT MIDI Display once again. https://youtu.be/hEpZ7Zy03Vo 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 … Continue reading TFT MIDI Display – Part 3 →

USBMIDI to MIDI Shield

I've been using my Korg Minikeys for testing a number of these projects, which usually means breaking out my Mini USB-MIDI to MIDI converter, but that means I need to find jumper wires, power, etc, so I thought it would be interesting to mount the appropriate components onto an Arduino pro-shield to create an entire "USB … Continue reading USBMIDI to MIDI Shield →

TFT MIDI Display – Part 2

Building on my previous project adding a colour display to an Arduino, I thought I'd use the graphics a little by adding one of those "show the note on the stave" displays you quite often get on modern keyboards. In Part 3 I preset an alternative visualisation. https://youtu.be/p_eLd95G4zc Warning! I strongly recommend using an old or … Continue reading TFT MIDI Display – Part 2 →

TFT MIDI Display

This project uses a cheap 1.8" colour 128x160 TFT display based on a ST7735 driver chip which is available very cheaply in the usual places. The display links up to an Arduino using the SPI bus as described here and there is a nice little library to talk to it provided by Adafruit for use … Continue reading TFT MIDI Display →
