  This experiment is a case study that applies a HCI-informed DMI Evaluation
Framework. This framework applies existing HCI evaluation methods to the
assessment of prototype Digital Musical Instruments (DMIs). The overall study
will involve a three-part analysis - a description and categorisation of the
device, a functionality evaluation that included an examination of usability
and user experience, and finally an exploration of the device's effectiveness
as a digital instrument. Here we present the findings of the first two parts of
the framework, outlining the constituent components of the interface and
testing the functionality of the device. The final stage of analysis will
involve a longitudinal study and will be carried out in order to assess the
musical affordances of the device.
