Mapping

Denon MC7000 (schematic view)

This controller is made for Serato DJ and most of the mapping is made for Mixxx accordingly. Anyhow, there are several differences for functions not matching the Serato mapping. If you have any wishes to improve the mapping, then please discuss it in the Denon MC7000 Mapping thread.

Mapping Settings

Denon MC7000 mapping settings

The MC7000 mapping features a number of options that can be customized from the preferences under Preferences > Controllers after selecting your controller and the DENON MC7000 mapping.

Jogwheel Settings

Setting	Variable	Default	Range	Description
Jogwheel sensitivity (\(s\))	jogSensitivity	1.0	0.05 to 10.0	Sensitivity factor of the jog wheel (also depends on audio latency). Use 0.5 for half and 2 for double sensitivity. Recommendation: Set to 0.5 with audio buffer set to 50ms Set to 1 with audio buffer set to 25ms Set to 3 with audio buffer set to 5ms
Enable jogwheel acceleration	jogAccelerationEnabled	false	true/false	If enabled, the track speed will accelerate faster than the physical jogwheel movement.
Acceleration exponent (\(x\))	jogAccelerationExponent	0.8	0.0 to 20.0	The exponent of the acceleration curve
Acceleration coefficient (\(c\))	jogAccelerationCoefficient	1.0	0.05 to 20.0	The coefficient of the acceleration curve

Jogwheel Acceleration

Enabling jogwheel acceleration will increase the scratch speed in proportion to the physical speed at which the platters are turned, similar to Serato. The precise formula for computing the scratch speed \(S\) from the physical platter ticks \(t\) turned is as follows:

\[S = \underbrace{st \vphantom{|}}_{\text{base speed}} \cdot \underbrace{c \cdot |st|^x}_{\text{acceleration factor}}\]

where

• \(s\) is the jogwheel sensitivity

• \(t\) is the number of physical platter ticks turned

• \(c\) is the acceleration coefficient

• \(x\) is the acceleration exponent

Упозорење

Be aware that the absolute track position will drift relative to the jogwheel position when enabling jogwheel acceleration! While this is convenient for scrubbing, this may make it less suitable for precise scratching.

Путоказ

An acceleration exponent \(x\) of 0 and a coefficient \(c\) of 1 are equivalent to no acceleration.

User Variables

The mapping can further be customized to suit individual needs via user variables inside the Denon-MC7000-scripts.js mapping file:

• MC7000.experimental activate experimental beat count feature (default: false)

• MC7000.needleSearchPlay activate NEEDLE DROP sensor while a track is playing (default: false)

• MC7000.prevSamplerStop set to single play samplers (default: true)

• MC7000.rateRanges set the available Pitch Fader ranges (default: 4, 6, 8, 10, 16, 24, 50, 90)

• MC7000.modeSingleLED set single LED on or off (default: 1). Can be toggled with SHIFT + Deck

• MC7000.VinylModeOn set the Vinyl Mode on or off at Mixxx start which also triggers the Platter Ring LED function (default: 1)

• MC7000.scratchParams set Scratch Parameters (default: 33+1/3, 1/10, 1/10/32)

• MC7000.SamplerQty set the sampler quantity (values 16 or 32, default: 16)

Sampler Mode (pink LED)

As default 16 samplers can be used. 8 samplers can be triggered from Deck 1 and Deck 3 and 8 samplers can be triggered from Deck 2 and Deck 4. Deck 1 will play sampler 1 to 8, Deck 2 will play sampler 9 to 16, Deck 3 will play sampler 1 to 8 and Deck 4 will play sampler 9 to 16.

Add samplers to the sampler bank pushing a pad button.

If a sampler is loaded, then another push on the pad button will play the sampler from its Cue point.

Push the pad button again while playing will replay the sampler from Cue point.

When a sampler is started while another one is still playing, then the initial sampler stops and only the newly triggered sampler plays (single play).

Use SHIFT + pad button to stop a sampler while playing or eject a sampler when stopped.

Путоказ

To use default Mixxx behaviour and allow playing multiple samplers at the same time you can set the user variable MC7000.prevSamplerStop inside the JavaScript file to false.

Velocity Sampler Mode (purple LED)

Velocity Sampler Mode is a mode where the velocity of the push on the pad determines the volume of the sampler played. A gentle push results in low volume and a powerful push restults in high volume. Apart from that the behavior is equal to Sampler Mode.

As default 16 samplers can be used. 8 samplers can be triggered from Deck 1 and Deck 3 and 8 samplers can be triggered from Deck 2 and Deck 4. Deck 1 will play sampler 1 to 8, Deck 2 will play sampler 9 to 16, Deck 3 will play sampler 1 to 8 and Deck 4 will play sampler 9 to 16.

Add samplers to the sampler bank pushing a pad button.

If a sampler is loaded, then another push on the pad button will play the sampler from its Cue point.

Pitch Play Mode (green LED)

Pitch Play Mode is a mode where the pad position determines the pitch of the deck played. After activating the Pitch, the pads light up in hotcue colors, waiting for a selection of existing hotcue for Pitch Play or creating a new hotcue at the current position. When a hotcue has been selected or created, this hotcue is used for Pitch Play.

During Pitch Play the range of pitch can be changed up or down using the param buttons.

start Pitch Play pushing a pad button after hotcue selection.

If the deck is playing, then another push on the pad button will start to play the deck with the assigned pitch from its Cue point.

To reset pitch press shift and pad button.

LEDs

The Channel Volume Meters matches to the ones shown in Mixxx GUI. Only when clipping the red LED illuminates.

The MASTER LEVEL meter is not correlated to Mixxx GUI as the controller handles that in Hardware.

Button LEDs are fully mapped for the first function. As you press and hold SHIFT then the secondary functions have only got some flashing LEDs mapped, e.g. TAP and KEY SYNC, when activated.

Press SHIFT + Deck to switch Platter Ring LED Mode.

• Mode 0 - Single ’off’ LED chase (all other LEDs are ’on’)

• Mode 1 - Single ’on’ LED chase (all other LEDs are ’off’)

Путоказ

The default mode can be set to 0 or 1 inside the JavaScript file.

Platter Ring LEDs are correlated with the VINYL button.

• If vinyl mode is enabled, the LED imitates a turntable platter spinning at 33.3 rpm.

• If vinyl mode is disabled, the current track position is indicated by the Platter LEDs starting at the top.

Белешка

The Platter Ring LEDs are not moving while the track position is ’negative’. That means if the position is before the track starts then the position LED keeps staying at most up position.

Known Issues

• Some Performance Pad modes are not available (Cue Loop, Flip, Slicer Loop).

• The Effect Units don’t use Mixxx’ Standard Effects Mapping
