Energy Panner: Free Auto-Panner Guide

Movement, not confusion

An auto-panner sends a sound left and right on a repeating pattern. Done well, it makes pads breathe and hats bounce. Done badly, it makes the mix seem unstable. This page is a practical playbook for Energy Panner or any similar tool: rates, depths, shapes and where to leave it out.

Four scenarios with settings

1. Ambient pad, slow drift

• Rate: 1 bar or slower (at 90 BPM that is about 2.7 seconds a cycle).
• Depth: 30 to 50 percent.
• Shape: sine, so the movement is smooth.

2. Rhythmic synth pluck

• Rate: 1/8 or 1/16 note, synced to host.
• Depth: 60 to 80 percent.
• Shape: square or triangle for a clear left/right bounce.

3. Hi-hat loop

• Rate: 1/4 note.
• Depth: 20 to 30 percent, so the groove stays centred.

4. Vocal ad-lib or effect throw

• Rate: 1/2 note.
• Depth: 50 percent, used only on the tail or an echo send.

Rules for a stable mix

• Keep kick, snare, bass and lead vocal centred. Panning them is rarely a good idea.
• Use auto-panning on two or three elements per song, not everything.
• Make sure the rate is synced when the pattern should lock to the groove.
• Check mono: a 100 percent pan will vanish half the time on a mono speaker.

Common problems and fixes

• Sound drops in level on mono: reduce depth, or use a stereo source rather than a mono one.
• Headphone seasickness: slow the rate and lower the depth.
• Timing feels off: check that the plugin follows host tempo and has no offset.
• Clicks at hard panning: use a smoother shape or a slight smoothing setting.

Two-minute A/B test

1. Play the section with the panner bypassed.
2. Enable it and lower the level of the panned track by 1 dB to compensate for perceived loudness.
3. Toggle mono. If it still works, keep it.
4. Ask if anything in the mix got harder to hear; if so, reduce the depth.

Combine with other effects

Auto-panning before a delay creates ping-pong echoes, and after a reverb it moves the tail. For a rhythmic delay to combine it with, see Wasser multiband delay. Panning changes perceived level, so keep your levels in check with the gain staging guide. Explore more free tools in the free VST collection.

Panning versus tremolo

An auto-panner shifts a sound between left and right, while a tremolo changes its volume. When you set a stereo panner to full depth on a mono source, you get something close to tremolo on each side in alternation. Knowing this helps you choose: use panning for space, tremolo for pulse, and both together for classic psychedelic textures.

Phase offset tricks

If your panner has a phase or offset control, offset two instances by half a cycle. One instance on the left-heavy layer and one on the right-heavy layer makes the sound circle without one side ever being empty. It is a useful way of keeping a wide pad from feeling lopsided.

Automation ideas

• Ramp the rate from a bar to a 1/16 note over four bars for a build.
• Drop depth to zero on the downbeat of a chorus for a clean centre impact.
• Sweep depth up during a bridge to add restlessness before the last chorus.

Worked example: an eight-bar synth arp at 128 BPM

Play a simple 1/16 arpeggio on a bright pluck. Add the panner with a triangle shape at 1/8 note and 50 percent depth. Listen for the bounce against the hi-hats; if both hit the same side together, shift the panner by half a step so the arp answers the hats. Then add a low-pass at 8 kHz to soften the highs and finish with a bit of delay. The arp now moves through the stereo field while the kick, clap and bass remain in the centre.

Troubleshooting

• Synth sounds weaker in one ear: the source may already be panned; centre it before adding the plugin.
• Effect vanishes in the mix: increase depth slightly or reduce competing wide sounds.
• Movement feels mechanical: change the shape to sine or slightly detune the rate against another modulation.

FAQ

Is auto-panning the same as widening?

No. A widener spreads a signal across the field. A panner moves it over time.

What rate suits a 120 BPM track?

A 1/8 note is 250 ms per step, a good default for plucks. Use a full bar (2 seconds) for pads.

Should I automate the depth?

Yes; raising depth into a chorus makes the section feel bigger without adding instruments.
