Oscillator Framework part 2: Variable Sample Frequency Wavetables

Oscillator Framework part 2: Variable Sample Frequency Wavetables

Who doesn’t love a wavetable synth? Who in their right mind doesn’t immediately think of a wavetable synth when cataloging the possibility tied up in an Arduino? Quite a few seem to be like minded as there are numerous blog posts and even a fairly in-depth article in Wired about implenting a wavetable synth on […]

DAC output circuit

DAC output circuit

While I was working on another post, I made a few recordings of the signal straight off the Due DAC and then recorded the same through the output circuit. I just thought I might share the sounds and screeenshots of the waveforms. The DAC output circuit is shown above. It’s basically a bandpass filter. But […]

A Generalized Oscillator Framework

A Generalized Oscillator Framework

One of the goals of this project is not only to provide a flexible hardware platform, but also to provide a framework around which you can develop patches more quickly with most of the boilerplate taken care of. A good opportunity for such a framework is a generalized voltage controlled digital oscillator. Generally, they all […]

Uploading a Sketch with the IDE

While we’re working on setting up some tools that will allow non-tech folk to upload preset-based sketches, here’s a brief tutorial on how to upload a sketch using the Arduino IDE over Bluetooth. Before you start this tutorial, please make sure you’ve set up the IDE correctly and that you’ve gotten Bluetooth pairing working correctly. […]

IDE Setup and Installation

If you’d rather upload binaries directly, please see this post. If you want to tweak and play, then you’ll need to set up the IDE. This page explains how to do that in a few steps. Prerequisites IDE You will need an nw2s::b which is based on the Arduino Due SAM microprocessor. If you are […]
