Also in this series, Three Different Ways to use Audio Analysis (or other data-source) to Trigger a Movie.
Using individual plugins to directly automate the control of different aspects of a live VJ performance or interactive installation can create some pretty awesome results, but one of the most powerful capabilities of VDMX is the ability to connect these plugins to each other to create more complex behaviors, interactions and visual effects.
To begin we'll add an audio analysis plugin and load in some media files to work with. The first trick will be to use the provided data-sources to drive to rate slider in the movie controls so that it only plays forward when there is an audio input. Alternatively the time slider can be directly driven by the values to scrub through the movie.
Next the same technique will be applied to an LFO plugin such that it only progresses forward or scrubs through the timeline of a waveform. By making a more complex piecewise waveform made up of sine waves of different frequencies and amplitudes we can make visual FX that become more intense as the audio level increases. This is particularly useful for FX like bump distortion that wobble around a center point.
Lastly we'll use slider presets to set up keyboard shortcuts for toggling each of these automations on and off during a performance.
