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 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!

Arduino PWM MIDI Synthesis with Mozzi

This project uses an off the shelf synthesis library to create complex sounds using pulse-width-modulation (PWM) on one of the Arduino's output pins. For further Mozzi experiments, you can take a look at Arduino FM MIDI Synthesis with Mozzi. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments.  I am not … Continue reading Arduino PWM MIDI Synthesis with Mozzi

Arduino R2R Digital Audio – Part 3

So this is where we start to get closer to some proper direct digital synthesis using the hardware developed in part 1 and moving on from the timer-driven code developed in part 2. In Arduino MIDI R2R Digital Audio I add MIDI. https://youtu.be/1MPNHMQ-2vs The essence of this project is to update the code so that rather … Continue reading Arduino R2R Digital Audio – Part 3

Arduino R2R Digital Audio – Part 2

Building on the Arduino R2R Digital Audio project, this uses the Arduino Timer functions to run our code in a more accurate and useful way.  I've now also added some potentiometers to my shield and a jack output socket. In Arduino R2R Digital Audio - Part 3 the code is developed further to support wavetable synthesis. These … Continue reading Arduino R2R Digital Audio – Part 2
