MainStage Add screen controls for the Playback plug-in
You can use screen controls to control the parameters of the Playback plug-in, display parameter values and the name of the audio file, and display the audio waveform of the audio file. The Screen Controls palette includes a waveform screen control that you can use with the Playback plug-in to view the waveform of the audio file. If the audio file contains markers, you can also view the markers in the waveform screen control.
Add a waveform screen control to the workspace
Click the Layout button (in the upper-left corner of the MainStage window) to switch to layout mode.
Drag a waveform screen control to the workspace, and position it as needed.
Note: If there is no Playback plug-in in the patch, an alert appears when you try to add a waveform screen control.
When you map the waveform screen control to the Playback plug-in, the waveform for the audio file loaded in the Playback plug-in appears in the waveform screen control. When you press the button you mapped to the Play/Stop parameter, the audio file starts playing, and you see the waveform move across the waveform screen control.
You can add screen controls for other parameters, including Fade Out, Cycle, Tempo, and so on, and map them to the corresponding parameters in the Mapping browser or in the Playback plug-in window. You can also map a parameter text screen control to the File field and have it display the name of the audio file being played.
