Vinyl control allows a user to manipulate the playback of a track in Mixxx using a real turntable as a controller. In effect, it simulates the sound and feel of having your digital music collection on vinyl. Many DJs prefer the tactile feel of vinyl, and vinyl control allows that feel to be preserved while retaining the benefits of using digital audio.

8.1. Kuinka se toimii?

Vinyl control uses special timecode records or CD’s which are placed on real turntables or CDJ. The audio output of the turntables is plugged into a audio interface connected to a computer on which Mixxx is running. When a record is played on one of the attached turntables, Mixxx reads the timecode from the record and uses the information to manipulate whatever track is loaded.

8.2. Mitä tarvitsen käyttääkseni sitä?

It is possible to use Mixxx’s vinyl control with a variety of setups. Unlike some proprietary DJ software, Mixxx can use several types of timecode media and any audio interface that your operating system has drivers to use. Optionally, any MIDI/HID controller can be used together with timecode control. The basic setups for timecode control are:

Laitteisto 1: Vinyl DJ

2-4 timecode vinyls, 2-4 turntables with phono pre-amplifiers (or line-level output), and 2-4 stereo sound inputs.

Your audio interface inputs must match the turntable outputs. Turntables output very quiet phono-level outputs that must be amplified for Mixxx to use. You should either find a audio interface that has phono pre-amplifiers built in (one for each deck), use standalone phono pre-amplifiers, or use turntables with built in phono pre-amplifiers.

You can try skipping the phono pre-amps if you use the software pre-amp in Mixxx on the Vinyl Control preferences pane. This may not work for everyone. Line-level signals are preferred and recommended.

For turntables a typical setup is depicted in the figure below. First, connect the RCA cables from the turntables to the inputs on your audio interface. Second, connect the outputs of your audio interface to the inputs on your mixer.

Many modern turntables have a Line/Phono select switch. If yours does, make sure it matches the input or switch setting on your sound card.

Laitteisto 2: CDJ

2-4 timecode CDs, 2-4 CD decks, and 2-4 stereo sound inputs.

Setting up CDJs for use with timecode CDs is similar to setting up turntables. The figure below outlines a typical configuration. First, connect the RCA cables of the CDJs to inputs of your audio interface. Second, connect the inputs of your mixer to the outputs of your audio interface. Make sure the input mode of your audio interface is set to Line.

Sound inputs

  • It is recommended to use a DJ audio interface that has multiple stereo line inputs on it.

  • Alternatively you can use multiple audio interfaces, each with a single stereo line in, but this is strongly discouraged.

Mixxx supports vinyl control input through a single audio interface with at least 4-channels of input (two stereo line-in jacks), or through multiple separate audio interfaces which each have 2-channels of input (a single stereo line-in jack). Vinyl control requires the use of stereo line-in jacks - Mono or microphone inputs will not work.

It is strongly recommended to use a audio interface that comes with native low latency drivers such as ASIO (Windows) or CoreAudio (Mac). Linux users depend on the quality of the corresponding open source driver.


For best scratch performance with vinyl control, we recommend using a system capable of latencies of 10ms. With higher latencies the scratch sound will start to become distorted.


An external hardware mixer is not required for using timecode control. You can use a MIDI or HID controller to mix in software instead.

Turntable Input Signal Boost

Many turntables provide unamplified “phono level” output which must be boosted to a “line level” signal. Normally, a mixer or audio interface provides this amplification, but if you’re plugging a turntable’s phono output directly into a audio interface that doesn’t support phono input, Mixxx can do the amplification. The Turntable Input Signal Boost slider allows you to adjust the level of preamplification applied to your decks’ signal. However, it is always preferable to use a proper phono preamplifier if you have one.

  • Vinyl Type: Several types of timecoded media can be used to control Mixxx. Configure the drop-down menus to match what type of timecoded media you are using on your decks.

  • Deck Vinyl Tempo: Change this if you prefer to scratch with your turntable or CDJ set at 45 RPM, default is 33 RPM.

  • Lead-in Time: Allows you to set a dead-zone at the start of your vinyl or CD, where the time code will be ignored. This is useful in situations where the time code begins very close to the edge of a vinyl which can make back-cueing over the first beat in a track tricky to do without your turntable’s needle falling off the vinyl. Setting a lead-in time of 20 seconds or more helps alleviate this by giving you more room on the vinyl to cue with. It’s also useful when you’ve worn the grooves at the edge of a control record to the point that it no longer works reliably: you simply set the lead-in so that the start of the tracks begin in good groove area. You can keep doing this until you run out of groove area, thereby decreasing your record replacement frequency.

  • Show Signal Quality in Skins: If enabled, a circular representation of the incoming timecode signal is displayed in real-time on the Vinyl Widget in the Mixxx Interface.


Although not recommended, you can use different kinds of timecode media per deck.


Mixxx has three control modes regardless of which control records you use.

  • Absolute Mode: Provides Mixxx with both pitch and position information from the timecode, and allows you to seek by needle dropping on your vinyl or seeking on your CDJ.

  • Relative Mode: Takes the position to be relative to your deck’s starting point, and only controls the pitch in Mixxx. It is not possible to seek using your deck in relative mode, with one exception. If you drop the needle in the Lead-in Time area (see Vinyl Configuration), Mixxx will seek back to the beginning of the track. Once a track is playing in Relative Mode, Mixxx will not allow you to select Absolute mode. Otherwise, the track would suddenly jump to a new position. Make sure the record is stopped and then you’re free to select Absolute mode.

  • Constant Mode: This special mode is usually only activated when Mixxx needs to keep playing a track even if the vinyl control signal isn’t present. Constant mode is automatically enabled when the needle reaches the end of a vinyl control record.

Cueing Modes

Mixxx has two optional cueing modes for vinyl control which only apply to Relative Mode. These modes are useful for quickly seeking to specific positions in a track without touching the laptop. Turntablists often need to find a break or a vocal sample, and cueing modes make these easy to find.

  • Cue: In this mode, when you drop the needle on the record after the Cue point, Mixxx will seek to that cue point.

  • Hot Cue: When the needle is dropped Mixxx will seek to the nearest hotcue point, working backwards. So if you have a hotcue at the one-minute mark, and another at the two-minute mark, you can drop the needle anywhere between one and two minutes and Mixxx will seek to the one-minute hotcue.


You can change the Control and Cueing Modes directly in the Mixxx user interface while mixing, go to Vinyl Control Mode and Cueing controls. Alternatively, use the Application shortcuts.

Signaalin laatu

A successful vinyl control setup hinges on good signal quality. Many factors can affect signal quality, but the most important one is ensuring the volume level of your timecode signal is moderate. A signal that is too loud or too quiet will cause adverse performance, often characterized by a loss of position data causing absolute mode to behave like relative mode.

Mixxx represents the quality of the timecode signal as a circular graphic coming from the vinyl control audio itself. The graphs correspond to your active input devices Deck 1 - Deck 4 .

If your vinyl signal is working, you should see a round, green circle drawn with two lines. This vinyl “doughnut” should be as circular as possible, and the lines should be clear with a minimum amount of fuzz.


You can display the signal quality in the Mixxx user interface while mixing, see Configuring Input and Output devices .

8.6. Yhden dekin hallinta

If you only have one turntable, you can still use Mixxx to play your sets. In the Preferences ‣ Sound Hardware ‣ Input tab, use the same audio input for both Vinyl Control decks.

When mixing, you’ll have one track playing automatically while the other is controlled by the turntable. Start by enabling vinyl control on the first deck, and start mixing. When you’re ready to cue up the next record, just disable vinyl control on the first deck and enable it on the second deck. Playback will continue on the first deck without interruption. Cue up the second track and mix it in. When you’re ready to cue the first deck again, just toggle the second deck off and the first deck on again.

Use the Application shortcuts to swap focus from one deck to the other. Alternatively, select Vinyl ‣ Single Deck mode in the Controller Wizard, to assign the control to a key on your controller.

8.7. End-Of-Record Mode

Sometimes the track you are playing is longer than the timecode area on your record. If the needle reaches the end of the vinyl timecode, Mixxx will enter a special End-Of-Record Mode. When this happens, the vinyl indicator (usually a green rectangle) will blink yellow as a warning. At the same time, Mixxx will automatically enable Constant Mode and will ignore the turntable’s pitch. At this point the track will simply continue playing until the end. When you load a new track, End-Of-Record Mode will be automatically disabled and Constant Mode turned off.

When you’re in End-Of-Record Mode and you want to still use the turntable for pitch control, simply lift the needle and place it anywhere in the main timecode area. It’s OK, the track won’t stop playing. As soon as Mixxx detects that the needle has settled, it will automatically switch to Relative Mode.

8.8. Control Track

Some vinyl control records have a special portion of grooves near the center of the record for selecting and loading tracks in the user interface. You can see these grooves because there is a gap between the main timecode area and the inner circle. Some control records have not been tested with Mixxx, and their control areas are not supported. Serato CV02 Vinyl and Traktor Vinyl MK1 are known to work. Serato CV02 CDs are known not to work.

Just drop the needle in the control area and let the record play forward or backward. The highlighted row in the library should move up or down. Simply lift the needle and drop it anywhere in the main timecode area to load the track.

8.9. Troubleshooting


To complete your setup you must configure Mixxx properly. Make sure you have:

  • specified Deck 1 - Deck 4 in Preferences ‣ Sound Hardware to route Mixxx’s output directly to the external mixer

  • specified Vinyl Control 1 - Vinyl Control 4 under Preferences ‣ Sound Hardware ‣ Input

  • selected the correct control type under Preferences ‣ Vinyl Control ‣ Vinyl type in the preferences. See the list of Supported Timecode media

  • enabled vinyl control via the menu under Options ‣ Vinyl Control ‣ Enable Vinyl Control.

Vinyl Control - No input configured

Vinyl control input channels not correctly set up. Vinyl control will not work.

Open Preferences/ Sound Hardware and set up the devices you want to use, see Configuring Input and Output devices

Vinyl Control - Receives no signal

Vinyl control input channels set up correctly. Waiting for timecode input signal.

Start your turntable or CDJ with the selected timecode vinyl or CD.

Vinyl Control - Receives good signal

Nearly perfect green doughnut about half the width of the graph. Rotating radar sweeps in the direction your record on the turntable is spinning.

Everything is OK, nothing to do. Go spin some beats.

Vinyl Control - Receives signal from wrong vinyl type

Incorrect choice of vinyl control source. Doughnut looks good but has a solid red color.

Select the correct vinyl type in the preferences. E.g. maybe you selected side B of the Serato Vinyl but your record is on side A.

Vinyl Control - Receives bad signal

Input signal is bad. As the vinyl signal gets worse, you’ll see the color of the doughnut change from green over orange to red.

Check the wiring / grounding on your turntable / CDJ. You timecode record / CD might be worn out or the needle on your turntable is dirty.

Vinyl Control - Signal goes in wrong direction

Wrong direction. The green doughnut looks good but the radar sweeps in the opposite direction of the record on your turntable / CDJ.

You probably have a wiring problem. Try reversing the left and right inputs on your turntable. You may also have to rewire the headshell.

Vinyl Control - Receives no timecode signal

Input signal is no timecode signal. Mixxx receives a normal audio signal while it expects a timecode signal.

Start your turntable or CDJ with the selected timecode vinyl or CD. You may want to check if the inputs devices are set up correctly in the preferences.

Vinyl Control - Receives mono signal

Left or right channel is missing. Mixxx receives only a mono signal but needs a stereo timecode signal to operate.

Check the wiring on your turntable / CDJ and also the headshell and needle on your turntable.

Vinyl Control - Receives too loud input signal

Timecode signal too loud. Mixxx receives a signal which has too much amplification.

Lower the amplification, either on your external mixer, audio interface, or with the Turntable Input Signal Boost.

Vinyl Control - Receives too quiet signal

Timecode signal too quiet. Mixxx receives a signal which has not enough amplification.

Boost the amplification, either on your external Mixer, audio interface, or with the Turntable Input Signal Boost.
