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.
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 soundcard 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.
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 soundcard 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:
Setup 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 sound card 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 sound card 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 sound card. Second, connect the outputs of your sound card 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.
Setup 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 sound card. Second, connect the inputs of your mixer to the outputs of your sound card. Make sure the input mode of your sound card is set to Line.
Mixxx supports vinyl control input through a single soundcard with at least 4-channels of input (two stereo line-in jacks), or through multiple separate soundcards 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 soundcard 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.
You can use any of the timecode media supported by Mixxx:
|Serato CV02 Vinyl||Very high|
|Serato CV02 CD||Very high|
|Traktor Scratch MK1 Vinyl||Very high|
|Traktor Scratch MK2 Vinyl||Not supported|
|MixVibes DVS V2 Vinyl||Very high|
At the present time, Serato records are recommended if you are looking to buy vinyl. If you want to use CDs, you can download a free copy for personal use from Serato.
Mixxx can be controlled by up to 4 decks with either timecoded vinyl or timecoded CDs.
You can configure vinyl control in Preferences ‣ Vinyl Control.
Many turntables provide unamplified “phono level” output which must be boosted to a “line level” signal. Normally, a mixer or soundcard provides this amplification, but if you’re plugging a turntable’s phono output directly into a soundcard 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.
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.
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.
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 .
For each deck, select Options ‣ Vinyl Control ‣ Enable Vinyl Control, or use the Application shortcuts.
A rectangle provides visual feedback with regards to vinyl control status of a deck.
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.
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.
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.
To complete your setup you must configure Mixxx properly. Make sure you have:
The graph is displayed in Preferences ‣ Vinyl Control, see Signal Quality.
|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 input channels set up correctly. Waiting for timecode input signal.||Start your turntable or CDJ with the selected timecode vinyl or CD.|
|Nearly perfect green doughnut about 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.|
|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.|
|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.|
|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.|
|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.|
|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.|
|Timecode signal too loud. Mixxx receives a signal which has too much amplification.||Lower the amplification, either on your external Mixer, soundcard or with the Turntable Input Signal Boost|
|Timecode signal too quiet. Mixxx receives a signal which has not enough amplification.||Boost the amplification, either on your external Mixer, soundcard or with the Turntable Input Signal Boost|
