Gemini G4V

g4v-top-4-893x490.jpg

The Gemini G4V is a 2 deck controller that supports 4 virtual decks, a 4 way mixer and has a built-in 4 channel USB soundcard.

It includes a Microphone input line, an Aux input line and an Booth output line. This lines are not going thorugh the soundcard but mixed directly at the controller. They are not accessible nor controlled by Mixx so they will not appear in any recording nor is possible to control them via the Mixxx screen interface.

This documentation is for the functionalities of the official controller (to be) included with Mixxx. For the documentation of the old controller available in the wiki, please use the Old Revisions button.

Mixxx Sound Hardware Preferences

  • Master output: channels 1-2
  • Headphone output: channels 3-4

Mapping Description

Most of the board's controls work as described in the G4V's manual, with a few exceptions. Snapshots of the board's labeling from the Manual are included below:

Shift

  • On each of the physical decks is a SHIFT button
  • This button, when held, changes the behavior of various buttons on that deck, labeled under the respective button

Mixer

  • In the middle of board, there are HIGH, MID, and LOW EQ, GAIN, and FILTER knobs for the individual virtual decks that work as normal

Crossfader

If the right button is lit up, the orientation of the virtual deck is to the right of the crossfader, and vice versa for the left button. If neither the left nor the right button are lit up, the virtual deck is centered on the crossfader

Deck Select Buttons

  • Just below the Tempo slider on either side of the board is a Deck Sel button (1|3 on the left and 2|4 on the right). These buttons toggle the controls on the board between the virtual decks.
