Plug-ins Window The Plug-ins window displays all the individual effects available for real-time use within Metro. You can double-click any individual effect to add it to an audio track, displayed in the Effects window. Metro and Metro SE support AudioUnits, third-party VST-compatible and Adobe Premiere-compatible Plug-in formats. AudioUnits and VST Plug-ins allow real-time processing of Audio Tracks as well as off-line processing of individual Audio tracks regions. Real-time processing allows multiple Plug-ins to be run in series across an Audio Track. The Premiere Plug-in format is limited to processing effects off line. All off-line effects processing is constructive - that is, Metro creates a new AIFF file for each non real-time process, leaving your original audio file alone. Audio Plug-ins are located in the Metro folder or in the Plug-ins directory located within the Metro folder. The Plug-in window displays all supported Plug-ins found when Metro was launched. Since they cannot run in real-time, Adobe Premiere Plug-ins display in gray. All Plug-ins in the Plug-ins window are also accessible under the Audio submenu within the Edit menu. Choose an Effect from the Audio submenu in order to perform a non real-time process of the current audio selection or Audio Track. Preview allows you to audition a portion of the effect before applying it. Preview time is limited to the For Playback Allocate setting in the Buffer Preferences. Select an Audio Track and double-click on one of the AudioUnits or VST effects in the Plug-ins window (Premiere Plug-ins are grayed-out). This opens the Effects window allowing parameter modification and routing configuration of one or more Plug-ins (multiple Plug-ins are routed in series). Add additional effects by double-clicking on other effects in the Plug-ins window. The number of simultaneous effects available is limited by CPU speed. Metro displays a message stating the 'Hard Disk is too slow for playback...' if too many effects are used across or within Audio Tracks.
