Pocket Gamelan: Tuning Microtonal Applications In Pd Using Scala, Greg Schiemer, M. de Coul 2010 University of Wollongong

Pocket Gamelan: Tuning Microtonal Applications In Pd Using Scala, Greg Schiemer, M. De Coul

Greg Schiemer

Microtonal tuning has been a characteristic common to many musical traditions yet despite a growing awareness of these traditions among many musicians today, a single system of tuning based on the twelve-note equal division of the octave continues to dominate development of multimedia applications. This paper describes a new software tool developed to export and document microtonal scales for use in computer music and multimedia composition. The tool was developed as a command script written by the first author using an editor, librarian, and analysis tool for musical tunings known as Scala, written by the second author. The tool called ...


Spatial Grains: Imbuing Granular Particles With Spatial-Domain Information, E. Deleflie, Greg Schiemer 2010 University of Wollongong

Spatial Grains: Imbuing Granular Particles With Spatial-Domain Information, E. Deleflie, Greg Schiemer

Greg Schiemer

Granular synthesis techniques have been appropriated for 3D sound spatialisation in a number of ways, such as the spatial encoding of individual grains. This paper proposes a new technique that aims to use the spatial information already encoded in ambisonic signals, the principle hypothesis being that this encoding is actually retained at the granular level. This opens up exciting new possibilities for spatial sound. The paper outlines some of these possibilities but focuses primarily on the synthesis of non-point sources of sound which forms the basis for a second hypothesis, involving functions that relocate spatially encoded grains in time.


Pocket Gamelan: Interactive Mobile Music Performance, Greg Schiemer, Mark Havryliv mh675@uow.edu.au 2010 University of Wollongong

Pocket Gamelan: Interactive Mobile Music Performance, Greg Schiemer, Mark Havryliv Mh675@Uow.Edu.Au

Greg Schiemer

In this paper, we discuss how mmobile phones have been used as devices for actively making music, how mobility can enhance the quality of sound, and how communication between moving sound sources can be integrated into the framework of a new genre of interactive performance involving groups of musicians. We identify some of the design limitations that stand in the way of developing new musical applications for mobile phones discussed against a background of performance works developed so far using this technology and point the way to future developments.

Greg Schiemer

In this paper, we describe the musical development of a new system for performing electronic music where a video-based eye movement recording system, known as Oculog, is used to control sound. Its development is discussed against a background that includes a brief history of biologically based interfaces for performing music, together with a survey of various recording systems currently in use for monitoring eye movement in clinical applications. Oculog is discussed with specific reference to its implementation as a performance interface for electronic music. A new work features algorithms driven by eye movement response and allows the user to interact ...


Haptic Carillon: Sensing And Control In Musical Instruments, Mark Havryliv, Greg Schiemer, Fazel Naghdy 2010 University of Wollongong

Haptic Carillon: Sensing And Control In Musical Instruments, Mark Havryliv, Greg Schiemer, Fazel Naghdy

Greg Schiemer

This paper discusses the proposed design of a hapticrendered practice carillon clavier. This instrument will produce a haptic feedback coupled with a responsive bell synthesis algorithm in order to replicate the authentic playing ‘feel’ and sound of a conventional mechanical carillon. An original classification scheme for haptic devices is presented with two principle goals: 1. to forge a conceptual understanding of the nature of a haptically-enabled version of a traditional instrument, and 2. to identify which existing haptic projects contribute towards a technical roadmap for the haptic carillon. Devices surveyed include both musical instruments and other applications that clarify the ...


Pocket Gamelan: Swinging Phones And Ad Hoc Standards, Greg Schiemer, Mark Havryliv 2010 University of Wollongong

Pocket Gamelan: Swinging Phones And Ad Hoc Standards, Greg Schiemer, Mark Havryliv

Greg Schiemer

In this paper, we discuss how mobile phones have been used as devices for active music making, how mobility affects sound and how communication between phones has been integrated into the fabric of a new genre of interactive performance by groups of musicians. We identify some of the issues that stood in the way of developing two new musical applications for mobile phones, discuss aspects of performance works developed so far using this technology and point the way to future development.


The Microtonal Legacy Of The Pocket Gamelan, Greg Schiemer, Mark Havryliv mh675@uow.edu.au 2010 University of Wollongong

The Microtonal Legacy Of The Pocket Gamelan, Greg Schiemer, Mark Havryliv Mh675@Uow.Edu.Au

Greg Schiemer

This paper examines the origins and motivation for the Pocket Gamelan, a performance interface for mobile phones where musical interaction between players is facilitated via bluetooth. The performance scenario for mobile phones has its origins in two works composed more than 25 years earlier. Mandala 1, composed in 1980 and Mandala 2, in 1981, were the first in a series of works in which an ensemble of players swing mobile sound sources while Mandala 3 and Mandala 4 were composed to be performed using bluetooth-enabled mobile phones. The Mandala series all have a common feature related to microtonal tuning. While ...


Orbophone: A New Interface For Radiationg Sound And Image, D. Lock dnl463@uow.edu.au, Greg Schiemer, L. Ong 2010 University of Wollongong

Orbophone: A New Interface For Radiationg Sound And Image, D. Lock Dnl463@Uow.Edu.Au, Greg Schiemer, L. Ong

Greg Schiemer

The Orbophone is a new interface that radiates rather than projects sound and image. It provides a cohesive platform for audio and visual presentation in situations where both media are transmitted from the same location and localization in both media is perceptually correlated. This paper discusses the advantages of radiation over conventional sound and image projection for certain kinds of interactive public multimedia exhibits and describes the artistic motivation for its development against a historical backdrop of sound systems used in public spaces. An account of an exhibit using the Orbophone is given together with description and critique of the ...


Pocket Gamelan: A Blueprint For Performance Using Wireless Devices, Greg Schiemer, Mark Havryliv 2010 University of Wollongong

Pocket Gamelan: A Blueprint For Performance Using Wireless Devices, Greg Schiemer, Mark Havryliv

Greg Schiemer

Mobile phone handsets have introduced new possibilities for musical interaction between multiple performers, as we reported in previous papers. Wireless communication between handsets now extends these possibilities even further. This paper describes development and implementation of a new performance scenario that involves remote instrument control using a Bluetooth connection. The paper proposes a low-level functional control protocol designed primarily around the current state of the mobile phone handset. The protocol makes provision for extended musical functionalities developed around tuning systems that are not adequately served by existing musical performance interfaces based on twelve equal divisions of the octave. Development is ...


Pocket Gamelan: Tuneable Trajectories For Flying Sources In Mandala 3 And Mandala 4, Greg Schiemer, Mark Havryliv 2010 University of Wollongong

Pocket Gamelan: Tuneable Trajectories For Flying Sources In Mandala 3 And Mandala 4, Greg Schiemer, Mark Havryliv

Greg Schiemer

This paper describes two new live performance scenarios for performing music using bluetooth-enabled mobile phones. Interaction between mobile phones via wireless link is a key feature of the performance interface for each scenario. Both scenarios are discussed in the context of two publicly performed works for an ensemble of players in which mobile phone handsets are used both as sound sources and as hand-held controllers. In both works mobile phones are mounted in a specially devised pouch attached to a cord and physically swung to produce audio chorusing. During performance some players swing phones while others operate phones as hand-held ...


Pocket Gamelan: A Pure Data Interface For Mobile Phones, Greg Schiemer, Mark Havryliv 2010 University of Wollongong

Pocket Gamelan: A Pure Data Interface For Mobile Phones, Greg Schiemer, Mark Havryliv

Greg Schiemer

This paper describes software tools used to create java applications for performing music using mobile phones. The tools provide a means for composers working in the Pure Data composition environment to design and audition performances using ensembles of mobile phones. These tools were developed as part of a larger project motivated by the desire to allow large groups of non-expert players to perform music based on just intonation using ubiquitous technology. The paper discusses the process that replicates a Pure Data patch so that it will operate within the hardware and software constraints of the Java 2 Micro Edition. It ...


Synthesising Touch: Haptic-Rendered Practice Carillon, Mark Havryliv, Fazel Naghdy, Greg Schiemer 2010 University of Wollongong

Synthesising Touch: Haptic-Rendered Practice Carillon, Mark Havryliv, Fazel Naghdy, Greg Schiemer

Greg Schiemer

This paper describes the design and construction of a prototype haptic carillon baton, and mathematical modelling of the carillon mechanism. Other research which haptically renders the grand piano mechanism inspires analysis of the kinematic constraints of the carillon mechanism. Analysis is used to construct a physical model using Simulink. This is then implemented numerically in a Java application. A microcontroller is programmed to interface the prototype’s motor and force sensor with a desktop Java application, allowing realtime simulation of the computational model in conjunction with the prototype. A strategy for containing all physical model computations on an AVR Microcontroller ...


Enabling Musical Applications On A Linux Phone, Greg Schiemer, E. Chen 2010 University of Wollongong

Enabling Musical Applications On A Linux Phone, Greg Schiemer, E. Chen

Greg Schiemer

Over the past decade the mobile phone has evolved to become a hardware platform for musical interaction and is increasingly being taken seriously by composers and instrument designers alike. Its gradual evolution has seen improvements in hardware architecture that require al-ternative methods of programming. Dedicated I/O in-struction sets for dealing with the idiosyncracies of vari-ous embedded peripheral devices are gradually being overtaken by I/O control using generic software that behaves more like operating systems developed for mainframe computers over three decades ago. This paper looks at the Neo FreeRunner, an open source mobile phone programmed using Linux. Its ...
