Grassi Box – Analysis

July 23, 2014 · Posted in Uncategorized · Comment 

The Grassi Box is a MIDI-to-relay piece of hardware (built by Dan Wilson of Circitfied) based on an Arduino teensy and some accompanying software tools built in Max. The idea is to be able to control a variety of my ciat-lonbarde instruments from a computer.

In this video the audio from the guitar is being analyzed (in real-time) to find the nearest preset/combination/permutation from a set of 6884 pre-analyzed presets.

LegoTechno 2.0 – Sliding Puzzle Sequencer (littleBits Synth + Arduino + CV + NI Maschine + Lego)

June 15, 2014 · Posted in Uncategorized · Comment 

A Lego Sliding Puzzle Sequencer Controls NI Maschine to sequence three littleBits Synth Kits through control voltage (CV) from an Arduino.
Also sends out OpenSoundControl OSC and audio to control reactive visuals on different computers.

Interacting with rythmic patterns through a tangible sliding puzzle allows for some interesting polyrythmic adventures.

What’s going on there?

Lego bricks can be placed on a eight transparent Lego base plates (16×16) to create rhythmic beat patterns.
Each of the eight baseplates holding the patterns can be moved around on a transparent surface. Whatever pattern (or part of a pattern) is placed in the center of the surface is filmed from below using a Webcam. The image of the brick pattern is analyzed and converted into Midi and OSC Messages that are sent to an Ardunio board, the Maschine Software (and another computer that generates dynamic visuals from the OSC Messages and the audio). An Arduino board turns the Midi Messages into control voltages to control three littleBits Synth kits that generate the sounds. Additional sounds can be injected from the Maschine software.

Made at Music Hack Day 2014 at the Sonar Festival, Barcelona.

8 step sequencer module with reverse, random, and offset — Sagittronics

March 5, 2014 · Posted in Uncategorized · Comment 

This is a sequencer that Charlie Slick built with an Atmega arduino chip.

The chip basically replaces the CD4017-or the like-but adds a few features like gate controlled reverse and random. The modules also has an offset input so you can use it like an arpeggio. There is no gate output but it does have an externally trigger reset.

Peff: Tesla Coil Samples

February 28, 2014 · Posted in Uncategorized · Comment 

oneTeslaburnout-1200

Peff has a new item out – a pulse wave oscillator called the oneTesla, here’s what he has to say about it:

For those who follow my social media streams, you may have already seen the various DIYAudio, DIYSynth, DIYrepair projects going on around here for the past year. One of these projects is the oneTesla Musical Tesla Coil kit. In “synth speak” it’s essentially a pulse wave oscillator. The oneTesla incorporates an arduino brain that receives MIDI note information, and the sparking plasma threads emitting from the coil oscillate at musical pitches. I certainly recommend the kit if you’re looking for a fun weekend project, however it may require some debugging and may also require the need for a function generator and oscilloscope. Over the past year it seems that the development team has ironed out the kinks in the design and even novices generally have great success in their builds.

The link below is an archive of the multisampled notes generated from the oneTesla. I’ve provided the archive as a folder containing an NN-XT patch. The audio was recorded at quite a distance from the Tesla coil, mainly because I didn’t want the coil to discharge through the microphone, but also because the output is incredibly loud. The recorded results aren’t as impressive as having the real-time audio-visual experience, so get a better “feel” of the actual sound, it’s recommended that you run the sampler output into a peak limiter and push the gain up 3dB to 9dB, and play the samples back at very high levels. The coil is sampled note-by-note from MIDI C0 to C5, and you will hear “spark” artifacts and a few obvious loop edits.

Groovesizer Alpha: infinite random, accents, pattern chaining

September 25, 2013 · Posted in Uncategorized · Comment 

http://groovesizer.com
A demo of infinite random mode, accents, and pattern chaining on the Groovesizer Alpha.

The Groovesizer (pronounced groove-a-sizer) is a DIY 8-bit audio platform. It’s a musical chameleon that can take on a number of different roles from sequencer to synth, drum machine, or midi controller. Exactly what the Groovesizer is at a given moment depends on the firmware it’s running. Existing firmware can be freely hacked, or new firmware developed using the beginner friendly Arduino IDE. Firmware is loaded to the board directly from the Arduino IDE, either via an AVR ISP programmer, or by flashing the Atmega chip on an Arduino board and swapping it out.

The Groovesizer is based around a custom PCB that features 6 potentiometers and  5 rows of 8 tactile switches and leds  (4 rows for the sequencer / trigger buttons and 1 row dedicated to control functions). It features an integrated Arduino clone, an 8-bit DAC option, an LM386 amp output, MIDI in/out/sync and is configurable to work with some of the most popular existing Arduino audio projects.

Furthest along in its development is the Alpha firmware which features a 3 oscillator monosynth attached to a 32-step sequencer with 112 memory locations to store patches and patterns.

Groovesizer Alpha & Doepfer Dark Energy: random patterns
