nw2s (November Whiskey Two Sierra) Arduino Eurorack Modular Platform

Note this is the first nw2s post. Videos below.

"The nw2s::b is an open, Arduino-based modular synthesis development platform for the Eurorack format with 55 independent interface points including CV and digital input and output jacks, knobs, buttons, and even audio. Yes, this module will allow you to emulate almost any existing sequencer, LFO, envelope generator, arpeggiator, quantizer, control voltage processor, hybrid oscillator, or other insane source of uncertainty.

More importantly, it will allow you to build nearly anything you can imagine.

The platform itself is a combination of hardware and software. The software provides a framework which allows you to configure the behavior of the module in a declarative syntax that should be relatively easy to pick up even for those with minimal programming experience.

The framework can easily be extended to provide a consistent development experience or it may be bypassed completely for access to the raw hardware.

Expansion possibilities are provided through the standard Arduino expansion ports which have been exposed via pin headers including I2C, SPI, GPIO, USB, and UART. Additionally, serial communication with a host can be established over Bluetooth."

nw2s::b modular control framework demo 01 Published on Oct 16, 2013 Scott Wilson·9 videos

"I've been developing a framework for algorithmic composition using microcontrollers such as the Arduino or Beagle. The code is currently supported on the Ardcore which runs on the Uno as well as the Due which is the board I'm using in a multi-output design.

The goal of the framework is to provide a number of modular building blocks on which you can design custom sequenced and algorithmic compositional tools.

This is a demonstration of a fixed ADSR generator and gate output that are based on a regular clock. The sound source is a Morphing Terrarium with the Z position modulated by the decayed gate output and the VCA modulated by the ADSR output. The X/Y position is unmodulated, but sent to a bubblesound SEM20 with the cutoff frequency modulated by an LFO.

Obviously, the ADSR is nothing in and of itself, but with any framework, the work to get to this point is mostly unseen. This is as much a POC of the framework concept as anything else.

I'm in the process of building a prototype that will be able to generate all of the control signals at once. Having all of them together makes a framework that much more significant.

And for a few more details... Outputs are digitized using a Radial DI amplified by a Daking preamp into an Avid HD IO. There's some Lexicon Random Hall, Valhalla Ubermod, and Soundtoys Crystalizer processing added afterwards.

For more information on the code, please see https://github.com/nw2s/b. I'll have some more information on the hardware prototyping soon. Just getting some details together."

nw2s::b probability triggers demo

Published on Dec 30, 2013

"This is another quick demo of what you can do with just a few lines of code in the nw2s::b. The probability trigger sequence is a sequence whose values are a set of percentage chances of a particular trigger event happening. Each sequence can be modified by an input value which reduces or increases the probabilities by a factor that varies from center.

In this specific demo, the clock is variable from 60 to 240bpm.

The triggers are hooked up to a Delptronics LDB-1e and the recording is dry.

I'm still running an acrylic cover. Preorders are on, and I'll be ordering the aluminum panels and production PCBs as soon as I get 30 pre orders. For more information, please see http://nw2s.net"
