Security and Stability in Network Connected Performances Environments
Scott Hewitt and Alex Harker
Published at the International Computer Music Conference, Ljubljana 2012
In this paper we highlight security issues generated by the use of network connectivity in performance. We argue that an awareness of these issues can lead to more secure and stable software, in both a technical and a musical sense. Potential exploits which might compromise performance integrity are illustrated along with suggestions for methods that alleviate such concerns.
Download PaperNotational Approaches for Laptop Ensembles
Scott Hewitt and Pierre Alexandre Tremblay
Published at the Symposium on Laptop Ensembles and Orchestras, Baton Rouge 2012
In this paper the authors will explore the notational approaches used while directing the Huddersfield Experimental Laptop Orchestra (HELO), HELOpg and other non meta-instrument based laptop ensembles. We will discuss the different notational methods used within my own compositional practice, suggest desirable notational features and suitability of such methods based on my own practice. In comparing western notation, graphic, graph, video, code and text scores we aim to identify a notational method suitable for the transfer of compositions between diverse ensembles.

Scott Hewitt, Samuel Freeman, Julian Brooks
Published at the Symposium on Laptop Ensembles and Orchestras, Baton Rouge 2012
A review of how the Huddersfield Experimental Laptop Orchestra Postgraduate Group (HELOpg) has developed its current methodology and practice through performance and collaboration since November 2009 through a consideration of the groups chosen approach to software, hardware and sound-reinforcement strategies as developed in and informed by;
- (1) regular weekly rehearsal; (2) various performances in different settings; (3) recent recording sessions
- divergence from more common laptop orchestra approaches
- defensive methods to ensure performance capability even through device failure
HELO: The Laptop Ensemble As An Incubator For Individual Laptop Performance Practices
Scott Hewitt, Pierre Alexandre Tremblay, Samuel Freeman and Graham Booth
Published at the International Computer Music Conference, New York 2010
In this paper we seek to outline the methodology and philosophy of the Huddersfield Experimental Laptop Orchestra (HELO). Placing the ensemble in context of similar work, we discuss the Do-It-Yourself (DIY) laptop instrument design paradigm, and the incubatory benefits that arise from participant-centered approach to ensemble rehearsal and performance.
Download PaperSound Communication: A Standard Syntax For Inter-Application, Inter-Device And Inter- Player Communication Over OSC
Scott Hewitt and Pierre Alexandre Tremblay
Published at the International Computer Music Conference, Belfast 2008
This paper offers a standard message format for easy intercommunication over a network, between laptop performers within a drop-in improvisation session. It is based on OSC-like reserved namespaces, namely /test, /setup, /chat, /app, /user, /time, /documentation and /hardware. We detail the syntax of use and provide worked examples. The proposed standard offers interoperability, extensibility and flexibility across network applications.
