What works with no gear
Serato has a mode built for exactly this case. The offline player runs whenever no Serato hardware is connected and outputs through the current default audio device. Two decks come from practice mode: the manual says it is there to practise combinations without compatible hardware connected, and the controls you need for that appear in the interface.
Rekordbox does not treat this as a special mode but as the normal case: the PERFORMANCE screen consists of a player panel and a browser panel, and inside the player sit the mixer, effects, sampler, headphones panel and enlarged waveform. Only a few of those need connected hardware — the microphone panel, the PAD EDITOR and PC MASTER OUT are explicitly conditional on it. The rest is there the moment the program opens.
The limit is in the sound card, not the software
Cueing means putting out two different signals at once, one to the room and one to your headphones. In internal mixer mode rekordbox asks for three assignments — master output, headphones output and booth output, each to an output channel. A computer with one built-in sound card has a single stereo output and cannot satisfy that.
That is the honest answer to the original question: a setup with no gear is a practice room, not a stage. Beatmatching, track selection, the shape of a set and every move you can see on screen — all of it can be learned here. You cannot play a night with it, because you only hear your next track when everybody else does. Know that limit and you can work inside it for months without spending anything.
Set up and practise your first transition
Seven steps, five of them one-off. The sixth is the one you have to relearn without gear — and the seventh the one you would otherwise never practise.
Pick a program and be honest about it
Both big programs let you mix with no gear, and neither hands you cueing. Take the one whose layout you will meet again on real hardware: rekordbox if the clubs near you run CDJs, Serato if the people around you play on Serato controllers. That decision matters more than any feature list, because you will not notice it on screen — you will notice it on your first device.
Switch Serato into practice mode
With no hardware connected, the deck-mode buttons in the top left toggle between offline and practice mode. The offline player is the single player for preparation; practice mode shows two decks and is where you drill combinations. Sound goes out through the current default audio device.
Open PERFORMANCE mode in rekordbox
The PERFORMANCE screen is made of the player panel and the browser panel; inside the player sit the mixer, effect, sampler and headphones panels plus the enlarged waveform. Whatever your subscription plan does not include, rekordbox marks in place with a symbol of its own — so you see what is missing instead of hunting for it.
Set the audio preferences once, properly
In preferences you pick the audio device and the buffer size. With no controller the buffer can be generous: it reduces audio skipping, and the latency it costs you only shows up when scratching. Leave mixer mode on [Internal] — [External] is meant for a connected mixer or controller and creates six outputs you do not have.
Assign four keyboard shortcuts before you start
Play left, play right, tempo up, tempo down — the beginning needs no more, and those four let you work two decks at once, which one mouse fundamentally cannot. Rekordbox has a keyboard shortcut function in preferences for this; in PERFORMANCE mode you need it anyway, because alphabet search does not work there. Serato names keyboard shortcuts as an equal way to drive practice mode and puts library navigation on the cursor keys.
Split the transition instead of playing it
A real blend needs two hands. With one mouse you turn it into two moves in sequence: bring the incoming channel up first, then pull the outgoing one back. It sounds different from a simultaneous blend, and it is meant to — what you are training here is not the movement but the ear for the moment it is due.
Work without cueing — and know what that costs
You hear your next track when everybody else does. The way out is preparation: set cue points in advance, know how each track comes in, plan the order roughly. That is exactly the work that makes the difference with gear too — only here you find out immediately when you have skipped it.
The moves that stand in for a mouse
A mouse moves one control. Anything that takes two hands on real gear either happens in sequence here or moves to the keyboard. Every move below is in the manuals — they are the difference between “sort of works” and “can actually be practised”.
| Move | What it does | What you need it for |
|---|---|---|
| Shift + drag | Turns a coarse control move into a fine one | In the BPM and pitch slider box and on the practice crossfader. Without it every mouse move overshoots, and beatmatching becomes guesswork rather than practice. |
| Control / command + click | Resets a control to its starting value | On the pitch that means zero per cent, on the crossfader the centre. The way back to a known state — with no detents to feel for, it is the only reliable zero you have. |
| Bend / nudge +/− | Adjusts the tempo momentarily | The stand-in for a jog wheel: the track slips forward or backward in time without changing the pitch you set. Hold control or command and it becomes a permanent fine tempo adjustment. |
| Cursor keys and control + F | Move you through the library without reaching for the mouse | The cursor keys act as up, down, forward and back; control + F jumps to the search box and leaves any crate on the way, so you search the whole collection. |
| Custom keyboard shortcuts in rekordbox | Put functions on the keyboard that would otherwise need the mouse | Assigned in the preferences window. In PERFORMANCE mode they are not a convenience but a requirement: alphabet search does not work there, and the manual points you at the shortcuts instead. |
| Raise the buffer size | Reduces audio skipping and increases latency | A trade that goes one way without a controller: the manual says the extra delay shows up when scratching — and you will not be scratching with a mouse anyway. |
What the two programs bring, in detail
Four points from the two manuals that appear on no product page — two per program.
Serato: practice mode, two decks
With no hardware connected the deck-mode buttons toggle between offline and practice mode. The manual says practice mode is there to drill combinations without compatible hardware — with a crossfader, channel faders and level meters, a BPM box and bend buttons.
Serato: the offline player for preparation
It runs whenever no Serato hardware is connected and outputs through the default audio device. Analysing, setting cues, building loops and opening the beatgrid editor all happen here — so with no gear you are missing nothing on the preparation side.
rekordbox: PERFORMANCE mode as the normal case
A player panel and a browser panel, holding the mixer, effects, sampler, headphones panel and enlarged waveform. Of those, only the microphone panel, the PAD EDITOR and PC MASTER OUT explicitly need hardware.
rekordbox: the meters that warn you
The global section carries an audio dropout meter that trips at 100 per cent and, on battery power, the computer's remaining charge. Neither exists on a controller — and without one, both are exactly what will wreck your evening.
Five mistakes that cost extra with no gear
Waiting for the controller instead of starting
The most expensive item on this list, because it costs months and returns nothing. Beatmatching, track selection and set construction need no gear — they need time, and time runs whether you own a device or not.
Reaching for sync because it is one click
On gear, sync is one button among many; with a mouse it is the easiest click on the screen. Which is why it becomes a habit faster here — and the ear you actually meant to train never gets used.
Trying to do the transition simultaneously
Two controls with one mouse is not a thing, and the attempt ends in a jump rather than a blend. Blending in sequence sounds different but is honest — the alternative is not practising the transition at all.
Playing without preparing
With no cueing, the next track is a surprise to everyone, you included. Setting cue points in advance and knowing how each track comes in is not a nicety here — it is what replaces the headphones.
Getting used to a workflow that only exists on screen
Mix with a mouse for six months and then stand in front of a controller, and half of it has to be relearned. Which is why it pays to choose the program by the hardware you will eventually meet — not by what happens to be open.
A note: everything about practice mode, the offline player and the mouse moves comes from the Serato DJ Pro manual (110 pages); everything about PERFORMANCE mode, output channels, mixer mode and buffer size from the rekordbox 7.2.16 manual (265 pages); both read in full, as of August 2026. There is nothing about Traktor here, because our Traktor source does not cover this case — a guess would be worse than a gap.
Frequently asked questions about DJing without a controller
Can I mix two tracks at all without a controller?
Yes. Serato has practice mode for exactly this: it shows two decks in the offline player and exists to practise combinations with no compatible hardware connected — the controls appear in the interface and respond to mouse or keyboard shortcuts. Rekordbox gives you a full player in PERFORMANCE mode, with mixer, effect and headphones panels. In both cases the sound comes out of the computer's ordinary audio device.
Can I cue in headphones without a controller?
Not with a single built-in sound card. In internal mixer mode rekordbox asks you to assign an output channel each to master output, headphones output and booth output — three separate destinations a computer with one headphone jack does not have. That is the real limit of a setup with no gear, and it is not a question of software but of the hardware underneath.
A mouse only moves one control at a time. What helps?
The keyboard. For practice mode Serato explicitly names mouse OR keyboard shortcuts, and keeps library navigation on the cursor keys; control + F jumps to the search box. Rekordbox has a keyboard shortcut function of its own, assigned in preferences — in PERFORMANCE mode you actually need it, because alphabet search does not work there. Assign the four or five moves you genuinely use and you have two hands instead of one.
The tempo jumps too far on every mouse move. Can it be finer?
Yes, and it is the move that makes practising without gear bearable at all. In the BPM and pitch slider box you click and drag up or down; hold shift while you do and the adjustment becomes fine. Control or command plus click resets the pitch to zero per cent. The same applies to the practice crossfader: shift for fine moves, control-click to reset.
What are the bend or nudge buttons for?
They are the mouse's stand-in for a jog wheel. A click adjusts the tempo momentarily and nudges the track forward or backward in time — exactly what a thumb on the platter edge does on a real deck. Hold control or command while clicking and the momentary correction becomes a permanent fine tempo adjustment.
The sound stutters even though I have no hardware attached. Why?
Usually the buffer size. A larger buffer reduces audio skipping but increases latency — scratching gets delayed. Without a controller latency barely matters, so you can afford to set the buffer generously. Rekordbox also shows an audio dropout meter in the global section that reacts before you hear anything; next to it, on battery power, it shows the computer's remaining charge, and a flat battery sounds much the same in the end.
What genuinely will not work without gear?
Three things are named in the manual, and all three need connected hardware: the microphone panel, the PAD EDITOR and PC MASTER OUT — the switch that sends master sound either to both the DJ equipment and the computer's internal speakers or to the equipment only. On top of that comes whatever your subscription plan blocks: rekordbox marks functions your plan does not include with a symbol of its own.
So when is a controller actually worth it?
The moment you start preparing transitions rather than playing them. Without cueing you hear your next track when everybody else does — you can learn beatmatching, track selection and the shape of a set under that constraint, but you cannot play a night. That is the honest limit: a setup with no gear is a practice room, not a stage. Knowing that, you can work in it for months without spending anything.
