JQ6500 MIDI MP3 Player Module – Part 2

Having played with my JQ6500 a little now, I just wanted to finish the project by building a shield to support the module's use with an Arduino Uno. 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 JQ6500 MIDI MP3 Player Module – Part 2 →

JQ6500 MIDI MP3 Player Module

As I mentioned last time, I want to turn m JQ6500 into a MIDI-driven sample player. This project describes how to do that. In part 2, I turn this into a simple shield. https://www.youtube.com/watch?v=_mvTisAVe5o&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 … Continue reading JQ6500 MIDI MP3 Player Module →

JQ6500 MP3 Player Module

I was given a JQ6500 MP3 Player Module to play with so I immediate saw the potential here to repeat my MCP4725 Sample Player experiment. In the next part, I add MIDI control. The JQ6500 module is designed to be the basis of a simple MP3 player, supporting the following features: Mono or stereo MP3 playback. … Continue reading JQ6500 MP3 Player Module →

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!

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 →

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 →
