In this Webel mini-tutorial trail for PureData synthesis you'll find some snapshots of patches used to create the "sound circles" animated logo for the PLAY music project. Each circle (created with GEM) corresponds to an evolving oscillator frequency with evolving amplitude and pan. There are 8 circles in all, 7 coloured after the optical spectrum, and one white outer circle, giving a composite sound with 1 base frequency and 7 harmonics (in the case where the ratio between frequencies is 2, i.e. an octave).

Some key diagrams about the Molonglo Observatory Synthesis radioTelescope (MOST) extracted from Dr Darren Kelly's honours thesis from 1988, An analysis of image formation by MOST (Molonglo Observatory Synthesis radioTelescope) , completed at the Department of Astrophysics, School of Physics, University of Sydney. These diagrams should help readers understand the MOST synthesis model and the notatation used elsewhere for this MOST zone.

Demonstration of the axes of a triaxial accelerometer using sound synthesis. The relationship to gravity is explored using vector acceleration with 3D Variable Frequency Oscillator (VFO) mode, then amplitude variation "triaxial chord" mode.

I present here, as adapted Unified Modeling Language (UML)TM structure diagrams, a simplified model of the hardware, data acquisition, and JSyn audio synthesis circuits of an earlier version of DranceWare for Drancing.

PureData/GEM

$dr$ of Webel is a Pure Data (PD) enthusiast. A PureData-based audio synthesis version of the DranceWare software for The Drancing accelerometer music "air instrument" uses GEM to synthesis rich visuals in real-time from accelerometer signals (such as WiiTM Remote signals), synchronised with the accelerometer music. The PLAY music project "sound circles" animated logo is synthesised using PureData/GEM, as described in this mini-tutorial
