How to Use Automation in Onomo (Make Your Tracks Move and Breathe)

A track where nothing changes — same volume, same filter, same everything, start to finish — sounds flat and lifeless, even if every individual sound is great. The thing that makes a song feel like it's moving is automation: changing parameters over time. The filter that slowly opens into the drop. The build that rises. The reverb that swells on the last word. This is the difference between a static loop and a song that breathes.

Onomo's automation is deep, and a couple of its features go beyond what most browser DAWs offer. Here's how to use it.

#What automation is, in one sentence

Automation is telling a parameter to change over time, automatically. Instead of a filter staying at one setting, you draw a curve so it opens up across eight bars. Instead of a steady volume, you fade it in. You "automate" the parameter, and it follows your instructions every time the song plays. Once it clicks, you'll want to automate everything.

#What you can automate

In Onomo you can automate the things that matter for movement and energy:

• Volume and pan — fades, swells, ducks, and moving a sound across the stereo field.
• Effect parameters — a filter's cutoff (the classic sweep), reverb amount, delay feedback, distortion drive — basically the knobs on your effects.
• Instrument parameters — things like a synth's filter cutoff, so the sound itself evolves as it plays.
• Tempo — yes, the BPM of the whole song can change over time (more on this below — it's a standout).

You can automate at the track level, on a bus, on the master, or on an instrument — so whether you want one sound to move or the whole mix to shift, it's covered.

#The moves that matter most

A few automation moves do most of the heavy lifting in modern music. Learn these first:

The filter sweep. The single most useful automation in electronic and pop music. Automate a low-pass filter's cutoff so it starts closed and slowly opens up — instant tension and release, perfect going into a drop or chorus. Reverse it (open → closed) to pull energy out for a breakdown.

The build / riser. Combine a few automations heading into a big moment: filter opening, volume rising, maybe reverb increasing. Stack them over 4–8 bars and you've manufactured anticipation.

Volume rides and swells. Automate a vocal or lead up a touch in its big moment, or swell a pad in under a section. Small volume moves make a mix feel hand-crafted instead of static.

The duck and the drop-out. Automate elements down (or out entirely) to create space — drop everything but the kick and vocal for a bar, then bring it all back. Arrangement is automation.

#Two things Onomo does that are a bit special

Tempo automation. Most people leave a song's BPM fixed forever, and a lot of browser DAWs don't even let you change it across a song. Onomo has a dedicated tempo lane, so you can draw a BPM curve — gradually speed up into a climax, slow into a breakdown, or do a subtle slow-down at the very end (the classic "rit." that makes an ending feel intentional). And because it's a real tempo track, it carries through correctly when you export. It's a pro touch that's rare in the browser.

Motion inside your automation curves. Beyond drawing a shape, you can add an LFO to an automation segment — a built-in wobble (sine, triangle, square, or saw) layered on top of your curve. So instead of hand-drawing every little oscillation for a wobble bass or a pulsing filter, you let the LFO do the repetitive motion while your drawn curve handles the overall direction. It's a fast way to get complex, living movement without tediously drawing it by hand. You also get different draw modes — straight lines, smooth curves, or freehand — so you can be as precise or as loose as you want.

#A simple way to start

If automation is new to you, do exactly one thing on your next track:

1. Put a low-pass filter on a synth or a whole section.
2. Automate its cutoff to start mostly closed and open up over the four bars leading into your chorus or drop.
3. Play it back.

That one sweep will teach you more about why automation matters than any amount of reading, and you'll immediately want to add a volume rise and a reverb swell to go with it. That's the craft in miniature: small moves, stacked toward tension and release.

#The bottom line

Automation is how a collection of good sounds becomes a song that moves. Automate volume and pan for dynamics, filter cutoffs for the sweeps that drive electronic and pop music, and effect parameters for evolving texture — and use Onomo's tempo lane and in-curve LFOs for moves a lot of browser tools can't do at all. Aim every automation at contrast — tension here, release there — and your tracks stop feeling like loops and start feeling alive.

#FAQ

What does automation do in music production? It changes a parameter over time automatically — like a filter opening across eight bars, a volume fading in, or reverb swelling on a word. It's what gives a track movement, dynamics, and energy instead of staying static.

What's the most useful thing to automate first? A low-pass filter's cutoff — the classic "filter sweep." Automate it to open up going into a drop or chorus for instant tension and release. It's the single highest-impact automation in electronic and pop music.

Can I change the tempo during a song in Onomo? Yes. Onomo has a dedicated tempo lane, so you can draw a BPM curve to speed up, slow down, or do a gradual ending — and it carries through when you export. Changing tempo mid-song is something a lot of browser DAWs can't do.

Do I have to draw every little movement by hand? No — you can add an LFO to an automation segment to handle repetitive motion (like a wobble or a pulse) automatically, while your drawn curve sets the overall direction. There are also freehand and curve draw modes for precision or looseness.

Is automation hard to learn? The concept is simple (change a parameter over time) and a single filter sweep teaches you most of it. Start with one automation per track and build from there.
