Intro 2 NIME

Instruments for the disabled

「NIME-01」那些为身障人士设计的乐器

每次在电视里看到身障人士强扭着原本就不太方便的身体去演奏乐器，然后被媒体宣传成催人泪下的励志故事，我总会想，为何就不能为他们打造一款特制的乐器呢？ ♬ 本文为NIME (New Interfaces for Musical Expression) 即音乐表达新接口系列的第一篇文章♬ ...

• Soundbeam - 1989
Soundbeam
Soundbeam assistive music technology used by people with special needs including PMLD, Cerebral Palsy, Autism, disability and in aged care. Special needs music. Music in Special needs. Music SEND. Special needs music. Music in Special Education. Disability. inclusion.

• inspired by Theremin
• multiple ultrasonic wave sensors → specific timbre
• distance → pitch

• Eye Conductor
Eye Conductor
Eye Conductor is a musical interface that allows people with physical disabilities to play music through eye movements and facial gestures. Using a $99 eye tracker and a regular webcam, Eye Conductor detects the gaze and selected facial movements, thereby enabling people to play any instrument, build beats, sequence melodies or trigger musical effects.

• focus → pitch, expression → timbre

• one handed bass
Making the one-handed bass
Accessible instrument design with Bela In this post Jacob Harrison introduces the one-handed bass, an instrument that mechanises the fretting hand of a bass guitarist using Bela and an array of solenoids. In summer 2016 we worked with the One-Handed Musical Instrument Trust ( OHMI) on a design project concerned with adapting the bass guitar for one-handed playing.

• foot sequencer → pitch

Making Instruments

• ink sysnth
Make A Paper Synth
With conductive ink and Bela In this post Nicolas Lewis talks us through making a simple and great-sounding synthesiser with conductive paint and Bela. I've been using Bare Conductive's electric paint for a few years now in various interactive projects as a way of controlling MIDI through capacitive touch.

• using conductive electric paint → connected with wire → potential meter → length of strip → change conductivity →continuous change in voltage
• different strips → different control in amplitude and frequency

• Sound map
Aural Fabric
An interactive sound map made with conductive textiles In this post Alessia Milo introduces Aural Fabric, a captivating interactive sound installation consisting of a textile map which plays back field recordings when touched. Aural Fabric is an interactive textile map allowing you to listen to selected field recordings by touching areas of the map that can sense touch.

• potential usage for visually impaired

• ceramic tile percussion
Making a percussion instrument with Bela
How low-latency makes beautiful percussion possible In this post we'll discuss building percussion instruments with Bela. Bela is a great platform for making self-contained digital musical instruments and particularly well suited to percussion instruments due the low levels of action-sound latency that can be achieved with the platform.

• ceramic is not conductive! so how?
• pressure sensor → voltage change
• this is targeting at the process of “sensing signals → sound signals”

• Chandelia
ChandeLIA
Sound, light and brass The ChandeLIA is a suspended musical instrument created by Lia Mice that transforms a chandelier into an audio-visual performance instrument. The performer creates a tone by striking or tapping the ChandeLIA (using their hand or a ChandeLIA baton), and can make changes to the tone, such as microtonal pitch shifts and adjustments to audio effects, by swinging, tilting and spinning the ChandeLIA.

? this doesn’t make too much sense to me....

• Sketches to sound!
Sketch Synth
Study to evaluate Sketch Synth, a sound synthesiser that is controlled through a visual sketch input.

• Steps for instrument makers!
• choose sensors: pressure, light, speed, distance, conductivity, touch(playtronica)
• read in sensor signals: Arduino, Raspberry Pi, BeagleBone(Bela)
• map signals to sound parameters: amplitude, pitch
• design timbre: Pure Data, SuperCollider, Max/MSP

Why Piano Rocks?

• What makes a piano piano?
• keyboard, keys → hammer(below) → hit strings → dampers(above) stop sound
• one key → 3 hammers?
• bass ( low pitch, long string, low frequency)
• treble (high pitch, short string, high frequency)
• complex sound by: resonance from soundboard, strings, sustain pedal(stop dampers)
• timbre: material, piano frame shape, height of keyboard, depth of keys, hammer size, diameter and tension of strings
• dynamics: forte, mezzo, piano

• What does tuners do?
• adjust keys and strings → so that each key matches to pitch name
• adjust hammers hardness and elasticity → remove noise, emphasize tonic, balance timbre

• audio engineering detour

Cicada

CICADA Sound Design Instrument | Physical Synthesis | New York

CICADA ACOUSTIC SYNTHESIZER Play with the building blocks of sound Tip-Surface Modulation At the core of Cicada is our patented tip-surface interaction between the bridge and the soundboard. Vibrations generated by the voice-coil motors in the actuator are transmitted and amplified by the bridge, causing intermittent interaction with the soundboard.
