Here’s how to record a keyboard: in most home studios you’ll either run a direct (DI) line from the keyboard’s outputs into your audio interface, or record MIDI to trigger a software instrument. Both give clean, noise-free results without a microphone. The right method depends on whether your keyboard is a digital piano, a synth, or a MIDI controller.
Let’s go through the options so you can pick the cleanest path for your gear.
How to record a keyboard: pick your method
There are three approaches, and many keyboards support more than one.
- Direct (DI) audio: connect the keyboard’s line outputs to your interface and record its sound directly as audio. Works for any keyboard with audio outputs — digital pianos, stage pianos, synths, workstations.
- MIDI: record the note data (which keys, how hard, how long) rather than audio, then play it back through a software instrument (VST). Lets you change the sound and edit notes after the fact.
- Microphone: only relevant if you want to capture an acoustic-style instrument with a real amp or speaker (rare for digital keyboards), or an organ through a rotary cabinet.
Recording a digital piano or synth via DI
This is the cleanest, simplest method for keyboards that have their own sounds.
- Find the keyboard’s line outputs (often labelled L/MONO and R, sometimes a headphone out as a backup).
- Connect them to the line inputs of your audio interface using appropriate cables (usually 1/4″ TS/TRS).
- Set the interface input to line level, not mic level, and disengage phantom power on those inputs.
- Record both L and R for a stereo signal if the keyboard outputs stereo (many pianos and synths use stereo effects).
Watch your levels — keyboards output a hot line signal, so set conservative gain staging to avoid clipping. If you only have one input, use the L/MONO output, which sums to mono. Most keyboards drive a line input happily on their own, but if you need to feed a long cable run or hit a mic input cleanly, a DI box can help match levels and reject hum.
Recording via MIDI for maximum flexibility
If your keyboard is a MIDI controller, or you want to keep your options open, record MIDI instead.
- Connect the keyboard to your computer by USB, or via a 5-pin MIDI cable into a MIDI-equipped interface.
- Load a software instrument (piano, synth, or sampler) on a MIDI/instrument track in your DAW.
- Play, and the DAW records the note data while monitoring the software sound.
The big advantage: you can change instruments, fix wrong notes, adjust timing, and tweak velocity after recording. The trade-off is some latency while monitoring software instruments — keep your buffer size low while tracking.
DI vs MIDI: which should you choose?
- Choose DI when you love the keyboard’s built-in sounds (a great stage piano, a vintage synth) and want to commit to them. It also bypasses latency entirely.
- Choose MIDI when you want to edit notes, change sounds later, or use better software instruments than the keyboard’s onboard ones.
- Best of both: some players record DI audio and MIDI at once, getting a committed sound plus the flexibility to re-amp through a VST later.
Getting the cleanest DI sound
A DI recording is only as good as the signal you feed in, so a few habits make a noticeable difference before you ever reach the mix.
- Use the keyboard’s line outputs, not the headphone jack, when you can. Line outs are designed to deliver a clean, full-level signal. A headphone output works in a pinch but adds the headphone amp’s colour and is easy to overdrive.
- Turn the keyboard’s master volume up to a healthy level, then set your gain on the interface. Running the keyboard quiet and cranking the interface gain just amplifies any onboard noise. A strong source with modest input gain keeps things clean.
- Decide on the keyboard’s built-in effects before you commit. Onboard reverb, chorus and delay are baked into a DI recording and can’t be removed later. If you’re unsure, record dry and add effects in the DAW, where you keep full control.
- Use balanced TRS cables for line outs that support them. Balanced connections reject hum and interference over longer runs, which matters in a home studio full of computers and power supplies.
Capturing expression: velocity, pedals and aftertouch
A keyboard part lives or dies on its dynamics, and both DI and MIDI workflows can preserve them — but only if you set things up to capture the detail.
For MIDI, make sure your controller is sending velocity so soft and hard notes register differently, and confirm a sustain pedal is connected and recording its data (controller 64). Many electronic pianos also send aftertouch or expression-pedal data, which is worth recording for pads and strings. If your playing feels stiff on playback, check that the software instrument is set to respond to velocity rather than playing every note at a fixed level.
For DI, the expression is already in the audio you capture, so play the part the way you mean it to sound. Resist the urge to flatten your dynamics — you can even out the loudest peaks later with light compression, but you can’t add musical phrasing back in after the fact.
Common mistakes to avoid
- Plugging a line-level keyboard into a mic input without padding it. The hot signal overloads the preamp and distorts. Use a line input, or engage a pad if your interface offers one.
- Recording mono when the keyboard’s character is stereo. Lush pianos and pads can lose their width and movement when summed to mono. Track both outputs if the part benefits.
- Leaving phantom power on for line inputs. It’s harmless on most modern gear but unnecessary, and on some older equipment it can cause problems. Switch it off for DI keyboard inputs.
- Monitoring through software with a huge buffer while tracking MIDI. The delay throws off your timing. Lower the buffer for recording, then raise it again when mixing to free up CPU.
- Forgetting to commit a tempo and metronome before recording MIDI. Editing timing and quantising is far easier when your MIDI lines up with the DAW’s grid.
Stereo, mono, and panning
Pianos and lush synth pads usually benefit from stereo recording for width and realism. Bass synths, leads, and mono organs are often better in mono — they sit more solidly in a mix and avoid phase issues. Match the recording to the part’s job in the arrangement, and if you want to go deeper on capturing width, our guide to stereo recording techniques covers the approaches in detail.
Mixing tips for keyboards
- High-pass non-bass keyboard parts to clear room for kick and bass.
- Carve space with EQ so piano and pads don’t clash with guitars or vocals — the same approach as our EQ and compression fundamentals.
- Light compression evens out dynamic playing on pianos.
- Reverb and delay place keyboards in the space; see our recording techniques hub for more.
Frequently asked questions
Should I record a keyboard with MIDI or audio?
Record MIDI if you want to edit notes and change sounds later, or use software instruments. Record audio via DI if you love the keyboard’s built-in sounds and want to commit, with no monitoring latency.
How do I connect a keyboard to my audio interface?
Run the keyboard’s line outputs (L/MONO and R) into your interface’s line inputs with 1/4″ cables, set the inputs to line level, and turn off phantom power on those channels. Record both outputs for stereo.
Do I need a microphone to record a digital keyboard?
No. Digital keyboards and synths sound cleanest recorded directly via their line outputs or through MIDI. A mic is only needed for acoustic instruments or keyboards played through a real amp or rotary speaker. If you want to capture an acoustic piano instead, see our guide to recording piano and keys.
Why does my keyboard sound noisy or distorted when recorded?
This is almost always a levels problem. If it’s distorted, you’re likely feeding a hot line signal into a mic input or setting too much input gain — use a line input and back the gain off. If it’s noisy or hissy, you may be running the keyboard’s volume too low and over-amplifying at the interface; raise the keyboard’s master output and use less input gain instead.
Can I record MIDI and audio from my keyboard at the same time?
Yes, and it’s a great safety net. Run the line outputs into your interface to capture the keyboard’s own sound as audio, while also recording the MIDI over USB. You commit to a sound now but keep the note data so you can re-trigger a different software instrument later if you change your mind.
