AD9833 MIDI Poly Signal Generator

Here are the details of how I added MIDI to my six-way AD9833 Poly Signal Generator shield building on the code that enabled the pots and switches from AD9833 Poly Signal Generator – Part 2. https://youtu.be/gnYn5I3gP9I Warning! I strongly recommend using an old or second hand equipment for your experiments. I am not responsible for any … Continue reading AD9833 MIDI Poly Signal Generator →

AD9833 Poly Signal Generator – Part 2

Following on from having built a six-way AD9833 Poly Signal Generator shield, its time to play with the pots and buttons. https://youtu.be/px4RQnccjmg Warning! I strongly recommend using an old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments or amplification! These are the key Arduino tutorials for … Continue reading AD9833 Poly Signal Generator – Part 2 →

AD9833 Poly Signal Generator

Something I wanted to do right from first getting hold of some AD9833 Signal Generators was to set several of them up on a single shield. This project shows how to drive four of them from an Arduino Uno. In part 2 I start to experiment with the controls. In the final part, I add MIDI. … Continue reading AD9833 Poly Signal Generator →

Arduino Tone Polyphony – Part 5

Ok, I thought I’d done with Arduino Polyphony for the time being, but something else came up today that I wanted to try. My post got a mention on the Hackaday blog and one of the comments has led me to a tweak that helps the tuning a little. https://youtu.be/lEaZhnjikfs Warning! I strongly recommend using old or … Continue reading Arduino Tone Polyphony – Part 5 →

Arduino Tone Polyphony – Part 4

In this final (for now) part of my Arduino Tone Polyphony project I'm returning to part 2 which was creating a stand-alone, full 12-note polyphonic tone keyboard with an Arduino Uno and committing it to an Arduino Shield using a proto-shield. Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino Tone Polyphony – Part 4 →

Single Pin MIDI Channel Selector – Part 2

As I mentioned in the Single Pin MIDI Channel Selector it would be nice to use a "DIP switch" on a small circuit board to give me my MIDI channel selection switch. Here is a small board that can plug directly into an Arduino's headers. Warning! I strongly recommend using old or second hand equipment for … Continue reading Single Pin MIDI Channel Selector – Part 2 →

Arduino MIDI 7 Segment Controller – Part 2

As mentioned in my previous post, the Arduino MIDI 7 Segment Controller is ripe for turning into a self-contained module. To keep it all relatively small, I opted to build an add-on board for an Arduino Nano. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any … Continue reading Arduino MIDI 7 Segment Controller – Part 2 →

Arduino Light Mozzi Generator – Part 2

I've spent a fair bit of time playing with the Control_Echo_Theremin example and finally committed it to stripboard. I was originally aiming for a fully self-contained module, speaker and all, but after a day or so trying to find a simple amplifier that works well with a PWM output, I've put that on hold for … Continue reading Arduino Light Mozzi Generator – Part 2 →

Auduino Granular Synthesis – Part 2

After having an initial look at the Auduino project, I was very interested in finding out more about how it worked, but the Internet seems somewhat mute on the subject and I've not found any information from the original author. If you know of such a link, be sure to let me know (at the … Continue reading Auduino Granular Synthesis – Part 2 →

LOLShield MIDI Lighting Effects

This project goes back to the LOLShield and uses it to trigger some LED animations in response to MIDI events. https://www.youtube.com/watch?v=Hu4hc7NGaGI&feature=youtu.be Warning!
