Reloop Beatmix 4

The Reloop Beatmix 4 is a performance-oriented 4-channel pad controller with integrated soundcard. It offers an ergonomically designed 4-channel mixer layout, optimized for the club allowing you to work intuitively: Dedicated equalizer and gain dials, high-quality line-faders, an extremely smooth-running crossfader, 16 multi-colour drum pads, as well as two extensive FX units are the foundation for your creativity.

Novo na versão 2.1.


This controller is a MIDI and audio class compliant device so it is compatible as-is with Linux, MacOS and Windows. On windows, the manufacturer ships an ASIO low-latency driver that can be found on the Manufacturer’s product page.

The MIC input is hardware-mixed and is not digitized so Mixxx can not have any control on the mic and you can not use ducking in Mixxx. The MASTER volume and PHONES volume knobs directly control hardware and don’t change Mixxx controls.

Transport Section

Jog wheel and pitch slider

Touch and move the jog wheel to scratch (either deck playing or not).

When playing, use the side of the wheel, without touching the metallic platter, to temporarily bend the pitch (speed up/slow down playback). When the deck is not playing, using the side of the wheel let you quick search through your track.

Hold SHIFT and turn the jog wheel to quick search through your track. SHIFT ignores touch sensitive platter so holding it and turning jogwheel is the same as using the side of the jog wheel.

When a deck is playing, jog led will turn around at 33.3 RPM. When track time left is below 30 seconds, jog leds will blink slowly, and when track time remaining is below 15 seconds, jog leds will blink quickly. These delays can be changed by editing the two variables at the beginning of the JavaScript file and eventually set to -1 to disable jog led blink.

The pitch slider let you adjust pitch.

PITCH +/- buttons let you temporarily adjust the the speed one step higher/lower. These buttons, when used with shift, let you control effects.

Effects Section

The effect section let you control the first two EffectUnits. There are two different effect modes mapped:

  • Multi Effect mode (the default), where you can load up to three effects in each EffectUnit and control then with the super knob
