- Base Power and Wiring Guide: ByteBeat devices are powered technology, so read this first if your grid is shaky.
Quick Answer
- The ByteBeat Device is an in-game music sequencer and synthesiser, added in Update 2.24 on 16 December 2019 (Hello Games billed it as Beyond development update 5).
- Buy the blueprint for 10 Salvaged Data at the Construction Research Station aboard the Space Anomaly. Each device costs Metal Plating x3, Gold x50, Antimatter x1.
- The ByteBeat Switch costs 2 Salvaged Data and Ferrite Dust x25, Ionised Cobalt x15. The ByteBeat Cable blueprint is free and the cable costs nothing to place.
- Devices need power. Wire one up and it plays a procedurally generated pattern immediately, before you touch a control.
- Editing has two layers: a sequencer with melody on top and rhythm below, and an advanced waveform view holding the maths that generates the tone.
- Snap devices together or join them with ByteBeat Cable to sync tempo and key and layer parts across machines.
- Songs save to a ByteBeat Library in the quick menu with eight track slots. You can copy tunes off any device you stand next to, including in other players' bases.
Overview
Most base parts in No Man's Sky do a job. The ByteBeat Device does not. It exists so you can write music inside the game, and it is the strangest thing in the build menu: a step sequencer bolted onto a maths-driven waveform generator, sitting in the same catalogue as storage containers and doors.
The name comes from a real demoscene technique. A bytebeat is a short arithmetic expression evaluated over a counter, producing sound as a side effect of the numbers. Hello Games wrapped that in a musical layer so you do not need the maths to get something listenable, but left the raw operators exposed for people who want them.
Be warned that the interface is fiddly. Everything runs through a grid of small cells and dials, there is no undo, and cursor movement on a controller is slow. Budget half an hour for your first track.
Unlocking the ByteBeat Parts
All three parts come from the Construction Research Station on the Space Anomaly, the same terminal that sells prefab rooms and generators.
| Part | Blueprint cost | Build cost | Role |
|---|---|---|---|
| ByteBeat Device | 10 Salvaged Data | Metal Plating x3, Gold x50, Antimatter x1 | The sequencer and sound generator |
| ByteBeat Switch | 2 Salvaged Data | Ferrite Dust x25, Ionised Cobalt x15 | Converts the music signal into pulsed electrical power |
| ByteBeat Cable | Free | No materials | Carries the music signal between devices and switches |
The Antimatter is the only real gate. If you are early enough in a save that Antimatter still feels precious, this is not the part to spend it on. For bulk currency, the Salvaged Data farming guide covers crashed freighter routes, and the wider unlock order sits in the base blueprints and unlocks guide.
Since the Endurance update in July 2022, ByteBeat modules can also be built aboard freighters, so a music room does not have to sit on a planet.
Placing and Powering Your First Device
A ByteBeat Device is powered technology and obeys the same rules as everything else on your grid: it needs a live connection, either through electrical wiring or through the prefab structure it is snapped to. The exact draw in kPs is not documented in any source we could verify, but it is small enough that a modest solar and battery setup runs several devices without complaint.
Borrow a habit from the community and put a normal wall switch between your power source and the first device. Music that plays continuously in your main hall gets old fast, and a switch kills the whole rig without dismantling anything. Interacting with a device also lets you adjust its volume, which matters once four of them share a room. If you have not dealt with wiring at all yet, start with the base building guide for beginners.
How the Interface Works
Interact with a powered device and the editor opens. Community write-ups and the original Hello Games post both describe two connected views rather than one flat screen.
The sequencer view is where most people live. The melody panel sits on the top half, the rhythm panel underneath. You toggle cells on and off to place note stabs and drum hits, and the playhead loops continuously while you work, so every change is audible the moment you make it. Surrounding panels set the musical frame: key, octave, tempo, and the arpeggiator.
The advanced waveform view exposes the arithmetic underneath. Rearranging mathematical operators and numerical inputs reshapes the tone itself, which is what makes one device sound like a bass and another like a hi-hat. A randomise function throws an entirely new formula at you, and it is the fastest way to find a sound you like.
| Control | What it does | Practical advice |
|---|---|---|
| Tempo | Sets beats per minute, defaulting to 115 | Drop to 80 to 95 for ambient base music; 115 is quite brisk |
| Key | Sets the musical key the notes are constrained to | Leave it alone until the melody works, then transpose to taste |
| Octave | Shifts the pitch range up or down | Set one device low for bass and another high for melody |
| Arpeggiator | Fills in notes automatically from your placed stabs | Turn it on for instant results, then reduce the note count to stop it sounding bouncy |
| Melody panel | Grid of cells for note placement | Start with four or five notes, not a full row |
| Rhythm panel | Grid of cells for percussion | A hit on beats one and three is enough to anchor everything |
| Waveform operators | The maths generating the raw tone | Randomise first, refine second |
We could not confirm a fixed published grid size for the panels, so treat them as however many cells your device shows rather than a specific number.
Making Something That Sounds Good
The pattern a fresh device produces is rarely pleasant. It is a demonstration, not a starting point. The reliable route to something you would leave running:
- Strip it back. Clear most of the melody cells. A sparse pattern of four or five notes reads as music. A full row reads as noise.
- Lower the tempo. 115 BPM suits a chase scene. Base music wants to sit under conversation.
- Fix the rhythm before the melody. Place a couple of percussion hits, let them loop until the pulse feels right, then write notes over the top.
- Use the arpeggiator sparingly. It fills gaps automatically, which is why unedited ByteBeats all sound alike. Cutting its note count is the biggest single improvement most tracks need.
- Randomise the waveform, do not build it. Roll the advanced view until a tone catches your ear, then nudge individual operators.
There is no undo, and an accidental randomise on a finished track is unrecoverable. Step out of the editor once you have something you like.
Layering Devices with ByteBeat Cables
One device is a loop. Several devices are an arrangement. Link them either by snapping the machines together so they share a wall, or by running ByteBeat Cable between them. The cable is the pink line in the build menu and is separate from electrical wiring, which still has to reach each device independently.
Linked devices share tempo and key, which is the entire point. Without that sync two loops drift apart within seconds. With it, you can give one device the bass line, one the percussion, and one the melody, and they stay locked together.
Community builds commonly run banks of roughly one to eight devices. We could not confirm a hard engine-imposed cap, so test before committing the Gold. Sound in No Man's Sky also attenuates with distance and is occluded by geometry, so a bank tucked behind a wall plays quieter than one in the open. Position matters as much as mixing.
The ByteBeat Switch and Reactive Lighting
The ByteBeat Switch turns a music box into a light show. It has one music socket and two electrical sockets: one to bring power in, one to send power out to whatever you want to drive.
Feed the switch a music signal over ByteBeat Cable, give it power, and it passes that power onward in bursts timed to your track. Wire the output to lights and they pulse on the beat. It is the same signal-and-power thinking used by proximity sensors and logic gates, so anyone who has built automated doors will recognise the pattern.
The obvious build is a lit dance floor. The subtler use is better: a slow track driving a few coloured lights along a corridor gives a base a pulse without turning it into a nightclub. Put one in the arrival room of your teleporter and base network and visitors get a proper welcome. It photographs well, which is worth knowing if you spend time in photo mode.
Saving and Sharing Songs
Finished songs live in the ByteBeat Library, reached from the quick menu under Utilities. It holds eight custom track slots.
To capture a song, stand near the device or bank, open the library, select an empty Custom Tracks slot, and hold the confirm input to copy the data from all nearby ByteBeat devices. Library tracks can be added to a playlist and played back through Utilities while you fly, alongside a set of Other Tracks the game supplies.
Sharing follows from this. Walk into another player's base, stand near their devices, and copy the song into your own library. That works in any shared session, which makes ByteBeat a rare creative thing to do when playing multiplayer with friends. Songs also travel as short encoded strings of roughly sixty characters, which is how people trade compositions outside the game, though getting one of those strings into a save usually involves a save editor rather than anything in-game.
Two things we could not confirm from an authoritative source: whether visiting players reliably hear a base's ByteBeat music under all network conditions, and whether a library track can be written straight back onto a device from the in-game menu. Test both in your own save before planning a build around them.
FAQ
Do I need to understand maths to use the ByteBeat Device?
No. The sequencer and arpeggiator produce listenable music without touching the waveform view, and randomise covers tone selection. The maths is optional depth.
Does the ByteBeat Device need power?
Yes. It draws from your electrical grid like any other base technology and starts playing the moment it receives power, so put a switch inline if you want silence on demand.
Can I put a ByteBeat Device on my freighter?
Yes. The Endurance update in July 2022 added ByteBeat modules to the freighter build menu, along with other decorative parts that had been planet-only.
How do I copy a song from someone else's base?
Stand next to their devices, open the quick menu, go to Utilities and then ByteBeat Library, pick an empty Custom Tracks slot, and hold the confirm input to copy from all nearby devices.
Why does my track sound like every other ByteBeat song?
Almost certainly the arpeggiator running at full note count over a densely filled melody grid. Clear cells, cut the arpeggiator's note count, and drop the tempo.
Is it worth Salvaged Data if I only care about efficiency?
No, and that is fine. ByteBeat produces nothing and unlocks nothing. It sits with decoration and photography among the things people do because the game is more than a spreadsheet. More in the tips and tricks hub.
Key Takeaways
- ByteBeat arrived in Update 2.24 on 16 December 2019, and the Endurance update later allowed the devices on freighters.
- Budget 12 Salvaged Data for the Device and Switch blueprints; the Cable is free. The real cost is the Antimatter in each device.
- Two editing layers: a sequencer for melody and rhythm, and an advanced waveform view for the maths. You only need the first.
- The default pattern is a demo. Sparse melodies, a slower tempo, and a restrained arpeggiator make a track listenable.
- Snap devices together or run ByteBeat Cable between them to lock tempo and key, then split bass, drums, and melody across separate machines.
- The ByteBeat Switch converts the music signal into pulsed power, which is how you drive lights in time with a track.
- The ByteBeat Library holds eight custom tracks, copies from any nearby device including other players', and doubles as a playlist while you explore.
