Status, October 2026: current. Rane still lists the FOUR.
What it is
The FOUR is a four-channel DJ controller for Serato DJ Pro from Rane, part of inMusic, announced in December 2022 and in stores from March 2023 (Rane product page). It sits beside the two-channel Rane One MKII, which has motorised platters.
It unlocks Serato DJ Pro while connected, with Stems included from version 3.0, and the box adds a licence for Serato Pitch 'n Time DJ. Algoriddim djay Pro 5.2 or later on Mac and Windows also supports it, and VirtualDJ needs a paid licence. Two USB-B ports take two laptops for changeovers.
Each deck has an 8.5-inch capacitive static jog wheel with a 320 x 240 colour display in the centre, and eight multi-colour pads with OLED displays above them. Pad modes include Stems, Hot Cue, Saved Loop, Roll, Sampler, Slicer and a Combo mode. Dedicated Acapella and Instrumental buttons remove or isolate vocals without leaving the current pad mode, and Stem Split puts the vocal on one deck and the instrumental on a sub-layer. The internal engine has 22 main effects and four knob-controlled channel effects, alongside Serato's software effects.
The mixer has four channel faders, a three-band EQ per channel and a tension-adjustable Mag Four crossfader with contour control. Channels 3 and 4 take turntables or players on switchable line/phono RCA inputs, with DVS through Serato's paid DVS Expansion. Outputs are main on XLR and RCA, booth on 1/4" and headphones on 1/4" and 1/8" jacks, plus two XLR/TRS combo mic inputs. It runs on an internal 100 to 240 V supply, measures 783 x 402 x 104 mm and weighs 8.27 kg. The box holds an IEC power cable, two USB cables, DeoxIT fader lube, the Pitch 'n Time card, stickers and manuals.
