Drawing automation lanes in Loop by Zaweba

A mix that stays exactly the same from the first bar to the last can sound static. Real tracks breathe: the filter opens over a build-up, the reverb swells at the end of a chorus, a part fades in rather than arriving all at once. Automation is how you make settings change over time, and in Loop by Zaweba it is drawn in lanes under the grid in Studio mode.

There are lanes for volume, pan, sends and every effect knob. Click to add a point, drag to move it, right-click to remove it. The lanes line up with the grid, so a change can start exactly on a bar.

How a lane works

A lane is a line across time for one setting. Each point you add fixes the value at that moment, and the setting moves from one point to the next as the song plays. Two points make a ramp; a flat line between two points at the same height holds the value steady.

Since every effect knob can be automated, anything you can set by hand in the effects chain can also change during the song.

Jobs automation does well

A fade in or out. On the volume lane of a track, or of the whole song's final part, put a point at the start of the fade at full level and another at the end at silence.

A filter sweep. Put the filter effect on a track, automate its cutoff knob from low to high over the eight bars before a drop, and the part opens up as the tension builds. This is a staple of house and other dance music.

A reverb or delay throw. Automate the send to bus A (reverb) or bus B (delay) on a lead vocal sound or a snare so it jumps up for a single beat at the end of a phrase, then back down. The echo rings out in the gap.

Movement across the stereo field. Automate pan to drift a pad slowly from one side to the other.

Drawing it neatly

Start with as few points as possible. Two points make a clean ramp; ten points on the same ramp usually just make it wobbly. Use the grid lines to place points on bar lines so changes land musically.

Turn on a loop region with L round the section while you draw, and listen each time it repeats. Automation is easier to judge by ear than by eye.

When automation fights back

Fighting your own automation is the classic one. If a track has volume automation, moving its fader in the mixer may seem to do nothing, or be overridden when playback reaches the next point. When a setting refuses to stay where you put it, look for a lane.

Another is automating too much. A few purposeful moves sound intentional; constant movement on every track sounds restless. And make big moves before small ones: get the fade and the build right first, then add the detail.

Where automation fits

Automation is the last step of mixing in most sessions. Arrange the song, balance the tracks in the mixer, add effects, then automate. Undo covers every edit, with 100 steps, so you can try a bold sweep and take it back if it doesn't work. Everything renders on your own computer, so what you hear in Loop by Zaweba is what goes into the exported file.
