Turn a pad into
a trailer pulse.
A rhythmic gate changes the volume of an audio source in time with your track. That gives a held chord a pattern without changing its notes. Start with a pad or a long guitar note, then shape how each pulse opens and closes.
From Cuekeeping, created by composer and guitarist Dallas Dwight.
Start with a sound that holds.
Use a pad with enough sustain to keep feeding the effect. A short pluck can disappear between pulses. For guitar, try a note or chord with a long tail. Keep the source simple while you find the rhythm.
Place the rhythmic effect after the instrument. With Pulse Maker, the input provides the sound and the plugin shapes its volume. You supply the sound; Pulse Maker supplies the movement.
Hear the pad before and after.
Watch the pad demo and compare the dry and processed audio. The recording shows Pulse Maker shaping a pad in Ableton Live.
Find the pace before adding weight.
Start with eighth notes against the cue. Switch to quarter notes if the part needs more room, or sixteenths if it needs more urgency. Faster isn't always bigger. Listen against the percussion and picture before deciding.
In Pulse Maker, Rate sets that pace. Length changes how much of each pulse stays open. A shorter Length separates the hits; a longer one lets the sound connect.
Shape the entrance and the gap.
Attack controls how quickly the pulse comes in. Release shapes the way it leaves. Try a softer entrance for an underscore that needs to sit behind dialogue. A sharper entrance can give a trailer cue more definition.
Depth controls how far the level falls between pulses. Pull it back for movement that leaves the pad intact. Increase it when you want clearer gaps. Listen at the same output level as you compare settings.
Build the section without crowding it.
Get the pulse working before adding distortion. In Pulse Maker, you can automate Build to open the filter and drive the section harder. Check the transition in context, especially when bass and percussion enter.
Build and Drive can push peaks above 0 dBFS. There's no built-in limiter, so leave headroom with Output and check the bounce. More level can sound more exciting during a quick comparison even when the part hasn't improved.
Rhythmic gate or tremolo?
Both change volume over time. A tremolo often gives you a smooth repeating swell. A rhythmic gate emphasizes the open and closed portions of the pattern. Attack, Release and Depth can soften that distinction, so choose by the shape you hear.
An arpeggiator changes which notes play. A rhythmic gate reshapes audio that's already there. If you like the chord but need it to move, try the gate first.
Should the rhythm follow the kick?
If another sound needs to control the movement, compare rhythmic gating with sidechain compression before choosing the effect.
