A right and left Motion Synth are being used to play four instrument sounds: a harp, a cello, piano, and a brass ensemble.
The visual was created in Processing and is responding in realtime to the same motion and touch data that is controlling the harp and cello sounds.
The left-handed Motion Synth is a prototype; currently only right-handed models are available from www.auug.com.

Blown ensemble: WIVI (Wallander Instruments) Cello: Bowed Strings Reaktor ensemble
Harp and piano: Kontakt
(Ableton Live hosted the above instruments as VSTs)
Visual: Processing – Download the free sketch here: http://auug.info/wiki/doku.php/public/processing_example
– Harp: Notes can be triggered from the touch screen or via Up-Down motion (all notes are from a pre-selected scale).
– Cello: Notes are being selected on the touchscreen. Volume and timbre are being controlled by velocity. Vibrato is proportional to changes in Up-Down orientation. Pitch glide speed is proportional to Forearm Rotation.
– Blown ensemble: Notes are being selected on the touchscreen. Volume and timbre are being controlled by velocity.
– Piano: Notes are being selected on the touchscreen, without any motion control.
Zones of Forearm Rotation are being used to crossfade between the various instruments.
