The Voes MX-12 3x4 is a fully programmable MIDI controller in the MX range from Belgian maker Voes, laid out as 3 rows with 4 buttons. It is aimed at players running a modeler or rack rig from a floorboard, sending up to 6 commands per layer, either all at once or step by step, so one press can change several settings across a rig1.

What it does

The MX-12 3x4 sends MIDI commands to connected gear. Voes lists 68 different command types, and among them 12 dedicated command types written specifically for the Fractal Audio Axe-Fx I, II and III and the FM3 and FM9, which covers the modelers many players pair a controller like this with1.

Each button is fully programmable, and the controller's working features break down like this1:

  • Layers: up to 6 commands per layer, sent all at once or step by step
  • Press types: normal press and long press, so a single button can cover two functions depending on how long you hold it
  • Expression control: 3 expression pedal inputs, with auto-engage listed for those inputs
  • Programming: every button fully programmable

Voes describes setup as quick: "In just 3 steps you get started in no time."1

The MX range

The MX-12 3x4 is one of two MX-12 layouts. The Voes MX-12 (2x6) shares the same core feature set but arranges its 12 buttons as 2 rows of 6 instead of 3 rows of 431.

Other models in the range include the Voes MX, Voes MX-5, Voes MX-6, Voes MX-9, Voes MX-18 and the Voes MX-EX, and Voes also publishes connection guidance for Line 6 gear that lists the MX-12 3x4 among its controllers2. For where a controller like this sits in a rig, see Midi Pedals.

The choice between the 3x4 and 2x6 layouts comes down to button arrangement: both are 12-button, fully programmable controllers with the same command set13.
