Bendit_I/O: A System for Extending Mediated and Networked Performance Techniques to Circuit-Bent Devices

Circuit bending—the act of modifying a consumer device\u27s internal circuitry in search of new, previously-unintended responses—provides artists with a chance to subvert expectations for how a certain piece of hardware should be utilized, asking them to view everyday objects as complex electronic instruments. Along with the ability to create avant-garde instruments from unique and nostalgic sound sources, the practice of circuit bending serves as a methodology for exploring the histories of discarded objects through activism, democratization, and creative resurrection. While a rich history of circuit bending continues to inspire artists today, the recent advent of smart musical instruments and the growing number of hybrid tools available for creating connective musical experiences through networks asks us to reconsider the ways in which repurposed devices can continue to play a role in modern sonic art. Bendit_I/O serves as a synthesis of the technologies and aesthetics of the circuit bending and Networked Musical Performance (NMP) practices. The framework extends techniques native to the practices of telematic and network art to hacked hardware so that artists can design collaborative and mediated experiences that incorporate old devices into new realities. Consisting of user-friendly hardware and software components, Bendit_I/O aims to be an entry point for novice artists into both of the creative realms it brings together. This document presents details on the components of the Bendit_I/O framework along with an analysis of their use in three new compositions. Additional research serves to place the framework in historical context through literature reviews of previous work undertaken in the circuit bending and networked musical performance practices. Additionally, a case is made for performing hacked consumer hardware across a wireless network, emphasizing how extensions to current circuit bending and NMP practices provide the ability to probe our relationships with hardware through collaborative, mediated, and multimodal methods

An Investigation into Non-linear Distortion Pedals with a Focus on Establishing a Lexicon to Accurately Describe Them.

This thesis attempts to identify and investigate the auditory impact distortion pedals impart on the source signal and consequently, how best to define, discuss and classify their individual, and collective, sonic signatures. This includes establishing a specialist lexicon with recontextualised descriptions for the specific adjectives of focus through means of both qualitative and quantative experimentation. This information is then visually represented by a ‘distortion wheel’ based in principle off the SCAA’s Coffee Tasting Wheel and how that allowed for the accessible retrieval of specialist terms within the contextual field. This is achieved through a series of etymological and audio-based analysis and experimentation. Qualitative experimentation was used to discover the initial descriptor list, critical sonic variables, and to subsequently define the words; quantative to match respective audio and signal analysis to the linked adjectives. The results showed ‘crunchy’ to be the most commonly used distortion descriptor. Through further analysis, it can be concluded that the Ibanez TS-9 is the crunchiest distortion pedal as its sonic features match closest to the defining traits of ‘crunchy’. Distortion pedals are subsequently successfully classified and descriptions for each adjective created to give the completed distortion lexicon

Sistema de Laboratorios Remotos para la práctica de Ingeniería de Control

For the development of laboratory practices, students work in physical devices or remotely, in person or remotely using Remote Laboratory Systems (SLR). However, current solutions do not have support or are proprietary, making it impossible to implement them for the development of Control Engineering practices in the Cuban Educational System. The present investigation describes a solution to the problematic one raised from the development of a System of Remote Laboratories that allows the development of practices of laboratories of Control Engineering. The proposed system allows the identification of systems, tuning of controllers and the execution of practices in real devices.

J-WAH : projeto e implementação de um Auto-Wah em Plataforma Teensy 3.6

O projeto tem como objetivo implementar uma versão digital do pedal de efeito conhecido como Mu-tron III. É realizado inicialmente um estudo do circuito do Mu-tron III, sendo este dividido em três blocos, chamados de blocos de Préprocessamento, Detector de Envoltória e Filtro de Variáveis de Estado. A placa de desenvolvimento Teensy 3.6 é utilizada para reproduzir de forma digital as etapas de processamento do bloco Detector de Envoltória e do bloco do Filtro de Variáveis de Estado. É elaborado um circuito que possibilite a leitura e escrita do sinal de áudio pela placa, onde é reproduzido o bloco de Pré-processamento do circuito original. Os algoritmos de processamento são elaborados inicialmente no software MATLAB R○ R2012b, e após são implementados no Teensy 3.6. É desenvolvido um software para a escrita dos algoritmos de processamento na placa de desenvolvimento, onde são determinadas as configurações de taxa de amostragem e resolução de leitura do sinal. São realizadas medições nas etapas de hardware e software do projeto, que são comparadas com medições realizadas em simulações do circuito original. São medidas as saídas dos blocos de Pré-processamento do circuito original e do circuito implementado para uma entrada senoidal, para os valores mínimo e máximo de ganho. O bloco Detector de Envoltória do circuito original e do projeto implementado têm sua resposta medida para uma entrada senoidal para seus dois modos de operação. O bloco do Filtro de Variáveis de Estado, tanto do circuito original quanto do projeto implementado, tem sua resposta em frequência medida nas suas três saídas para valores mínimo e máximo do fator Q. Ao realizar a leitura das medições realizadas, concluiu-se que o método proposto possibilitou uma reprodução satisfatória do efeito para valores baixos de ganho na etapa de Pré-processamento. A etapa de Pré-processamento proposta no projeto não apresentou êxito pleno na reprodução da etapa do circuito original devido à sua faixa limitada de valores de ganho de operação, constituindo-se na principal limitação do projeto implementado.The project has as its main objective to build a digital version of the effect pedal known as the Mu-tron III. Initially a study of the Mu-tron III is realized, with it being divided in three blocks, known as the Preprocessing block, the Envelope Detector block and the State Variable Filter block. The Teensy 3.6 developing board is used to reproduce digitally the processing steps of the Envelope Detector and the State Variable Filter blocks. A circuit that makes the reading and writing of the audio signal from the board is built, and there the Preprocessing block of the original circuit is reproduced. The processing algorithms are made initially in the MATLAB R○ R2012b software, and later are implemented in the Teensy 3.6. A software for the reading/- writing process in the developing board is made, where configurations like sampling rate and reading resolution are determined. Measurements are made in the project’s hardware and software steps, and these measurementes are compared with measurements made in simulations of the original circuit. The outputs of the Preprocessing block of the original circuit and of the implemented circuit are measured for a sinusoidal input, for minimum and maximum gain values. The Envelope Detector block from the original circuit and from the implemented circuit have their responses measured for a sinusoidal input for both of their operating modes. The State Variable Filter block, from the original circuit and from the implemented circuit, have its frequency responses measured in the three filter modes and for minimum and maximum Q factor values. Analysing the measurements made, it’s concluded that the proposed method made possible to reproduce successfully the original pedal for low Preprocessing gain values. The Preprocessing step that is proposed in the project have not been fully reproduced the original block due to it’s limitations in the operational gain, being the main limitation in the implemented project
