When Sync is enabled, the Delay time synchronizes to the Pro Tools session tempo. When Sync is disabled, you can set the delay time in milliseconds independently of the Pro Tools session tempo. The Sync button is lit when it is enabled.
When Sync is enabled, the Delay control lets you set the main delay length in 16th note lengths (based on the Pro Tools session tempo).
When Sync is disabled, the Time control lets you the main delay time in milliseconds and seconds.
The Feedback control lets you adjust the amount of delay feedback. At 0% the delayed signal repeats only once. As you increase the feedback, the number of times the delay repeats increases. At 100%, the delay doesn’t repeat indefinitely, but it does last a very long time!
The From and To controls let you feed signal from one delay Tap to another, or back to the main input, to create complex delay/feedback effects.
The To control sets the tap (or the main input) that the cross-routed signal will be routed to.
The High Cut control lets you adjust the frequency for the High Cut filter. For less treble, lower the frequency.
The Low Cut control lets you adjust the frequency for the Low Cut filter. For less bass, raise the frequency.
The Mix control lets you balance the amount of dry signal with the amount of wet (delayed) signal. At 50%, there are equal amounts of dry and wet signal. At 0%, the output is all dry and at 100% it is all wet.
