Behringer Cmd Mm 1

Behringer CMD MM-1

• Forum thread

The Behringer CMD MM-1 is a flexible controller that controls 4 decks by default. The mapping can be easily configured to control any combination of decks and effect units.

The pictures above are a render and a real life photo. All following examples will be made with a help of a 3D model.

This demonstration video shows how the mapping works by default with every channel in Deck mode:

Mapping description

Mapping options

There are four global variables at the top of the script file:

• channelNumber: The standard MIDI channel number of the CMD MM-1 is 5 but it can differ. If that is the case, you can change it here.
• invertColor: Swaps the colors which suits certain skins more
• defaultChannelSequence: Defines how the channels are mapped when Mixxx starts
• channelMode: Defines if a channel is in Deck or FX Mode when Mixxx starts
• standardKnobBehavior: Defines the mapping of the knobs when Mixxx starts

Modifiers

There are two modifier buttons in this mapping, [SHIFT] and [CTRL]. These allow each button to have up to four functionalities. They behave like the normal Shift and Control keys on a computer keyboard. Most of the features can be explained via the renderings where the functionalities are marked by the formatting of the Text ([SHIFT] and [CTRL]).

Channels

Each Channel can be put into Deck or FX Mode, as well as reassigned to a different Deck/FxUnit on the fly or via a variable at the top of the script. This makes it possible for people that only use two decks to use the other channels for controlling an EffectUnit instead of wasting the unused controls.

Top row

The Out 1 knob controls the Master balance and the Out 2 knob controls the Master gain.

You can see the L/R buttons besides the encoder as Shift and Ctrl buttons.

The encoder in the middle is able to browse the library and jump on the preview deck (16 steps) while holding shift. When pressing the encoder, the selected/highlighted track in the library gets loaded into the preview deck. The preview deck can be played/paused when holding shift while pressing the encoder down.

The Cue Vol/Mix knobs have no alternative functionality.

Knobs

The Knobs have three different mappings which can be cycled while in operation. (more on that later) The first one is the standard [High,Mid,Low,Quickeffect]-Combo. The second one shifts everything up and is mapped to [Gain,High,Mid,Low] which some people might prefer. The third one controls the EffectUnits [Meta1,Meta2,Meta3,Mix]. The Effectunit is based on the channel/deck number, so the channel that controls the knobs/buttons/faders of channel 1 also controls the knobs of EffectUnit1, Channel 2 controls EffectUnit2, etc.

FX Mode

The Knobs in FxMode overwrite the assigned mapping and are mapped as [Effect 1 Meta, Effect 2 Meta, Effect 3 Meta, Super] and the fader is also mapped to the mix of the EffectUnit. The buttons are documented in their own section.

MiddleButton/exShift

• Normal: toggle maximize library
• Shift: recenter Crossfader
• Ctrl: Cycle Knob assignment (swaps the mapping of the knobs as mentioned earlier.
• Third: Reassing Channel Sequence (resets mapping back do the global defaults (look at global vars))

Buttons

Deck Mode

[1]&[2] Buttons:

• Normal: Change Crossfader side (Orientation)
• Shift: Toggle Fx1&2 for desired Channel
• Ctrl: Toggle Fx3&4 for desired Channel
• Third: Change ChannelNumber/Assignment

[CUE] Buttons:

• Normal: Pre-Fader-Listening
• Shift: Load selected Track to Deck
• Ctrl: Enable Fx-PFL for Unit according to channel number.
• Third: Change Channelmode

FX Mode

[1]&[2] Buttons:

• Normal: Toggle Channel1&2 for desired FxUnit
• Shift: Toggle Channel3&4 for desired FxUnit
• Ctrl: Toggle Effect 1&2 in desired FxUnit
• Third: Change ChannelNumber/Assignment

[CUE] Buttons:

• Normal: Pre-Fader-Listening for FxUnit
• Shift: assign to master
• Ctrl: Toggle Effect 3 for desired FxUnit
• Third: Change Channelmode

Faders

DeckMode:

• Normal: Volume Fader
• Shift: Rate-/BPM-Faders

FxMode:

• EffectUnit Mix (dry/wet)

Reassigning channel mode and number

The channel modes and numbers can be set by changing the #mapping options at the top of the script. They can also be changed while using the controller when in thirdMode. Pressing the cue- button toggles between Deck and FX Mode. The Channel number is assigned with the [1]&[2] buttons.

They are mapped in a sort of two bit encoded system:

• & [ ] = Channel 1
• & [ ] = Channel 2
• & [x] = Channel 3
• & [x] = Channel 4

So you can change between channel 1&3 by pressing the [1] button, and channel 2&4 by pressing the [2] button.

Troubleshooting

Controller does not light up

The issue is probably the MIDI channel of your MM-1. Behringer has a tool that can set the controller to a different MIDI channel. So your controller is probably set to the wrong channel. The easiest way to fix this is to use Behringers tool and set it do MIDI channel 5. https://musicgroup-prod.mindtouch.us/04_BEHRINGER/CMD-_How_Do_I_Change_MIDI_Channel_On_My_CMD_Controller%3F If you can't do that for some reason, you have to find out the channel your MM-1 is sending on at the time. Once you know that you should go change the line where it says "var CHANNELNUMBER = 5;" of the file "Behringer-CMD-MM-1-Advanced.js" in the folder with the mappings so there is the number of your channel instead of the 5. (IMPORTANT: NO PARENTHESES). The you have to find the file "Behringer CMD-MM-1.midi.xml" in the same folder and replace the 4 at the end of 0x94, 0x84 and 0xB4 with your CHANNEL-NUMBER MINUS 1. Restart Mixxx and then it should work.
