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 →

AD9833 MIDI Signal Generator

This project adds MIDI receiving to the AD9833. In part 2 I add a second oscillator. In this final part, I add multiple oscillators. https://www.youtube.com/watch?v=E7y-fDsf5tE&feature=youtu.be Warning!

AD9833 Signal Generator

I've picked up some cheap AD9833 based signal generator boards which look particularly interesting as they are programmable frequency generators capable of generating a sine, square or triangle wave at frequencies up to 12.5MHz and are controlled using the SPI bus from the Arduino. In part 2, I add some simple controls. In this part, … Continue reading AD9833 Signal Generator →

WS003 – Drums and Touch

This is the next of my worksheets collecting together a number of related projects with a single list of parts and a suggested "building order". This time all relating to touch interfaces or percussive projects. This worksheet links together the following projects: Arduino Relay Bolero Arduino MIDI Relay Drumkit Arduino MIDI Relay Servo Drumkit Instant … Continue reading WS003 – Drums and Touch →

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 →

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 →

OLED MIDI Display – Part 2

As I mentioned in my previous post, it should be possible to connect multiple displays to the same microcontroller. This projects looks into that in a bit more detail. Spoiler - it almost works, but has software limitations! Read on for details. Warning! I strongly recommend using an old or second hand keyboard for your MIDI … Continue reading OLED MIDI Display – Part 2 →

OLED MIDI Display

Following on from my experiments with colour TFT displays, this project takes a cheap monochrome OLED display and puts it to use with MIDI. In Part 2 I almost manage to get two displays working! https://youtu.be/Ayp-f-wmYkE Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for … Continue reading OLED MIDI Display →
