‌The R4 MultiTrak is the world’s first portable multi-track compact studio supported by 32-bit Float audio technology. Built around Zoom’s popular handheld design, the R4 will provide musicians and songwriters with an enticing new mobile device for layering music tracks, whether recording a demo or building an original tune, with pro-audio quality and the greatest benefit of clip-free recordings.

RECORD. BOUNCE. REPEAT.

With the R4, you can record up to four tracks, mix and then bounce them to the dedicated ‘bounce track.’ This lets you free up additional tracks to keep adding layers. You can also ‘undo’ your last bounce, allowing you to mix your tracks further or record new ones if necessary.

32-BIT FLOAT RECORDING

Don’t worry about your audio signal clipping. The R4 captures perfect audio with every take, without the need to set gain.

COMBO INPUTS

The R4 has 2 XLR/TS combo inputs with tried and tested Zoom preamps. You can plug in microphones, instruments, keyboards, and more.

ADD SOME EFFECTS

Track Effects

Each track features a 3-band EQ, pan, echo, and reverb to refine your mix.

Input Effects 

Apply effects to input A such as amp simulations, delays, distortions and more.

BUILT-IN MICROPHONE

The R4 features a high-quality built-in microphone, perfect for acoustic guitars, vocals, or capturing a quick reference recording.

MUCH MORE THAN A METRONOME

The R4 has a rhythm section preloaded with over 80 different drum patterns to play along with featuring genres such as rock, hip hop, funk, heavy metal, and more.

EVERY TAKE IS SAVED

Tracks that you record are automatically saved individually, even after they have been bounced. These tracks or any other audio files can be loaded into a project on the R4

32-BIT FLOAT AUDIO INTERFACE

The R4 is also a powerful 2-in/ 2-out USB audio interface with 32-bit float technology. Connect it to either your computer or smartphone.

CONTROL AND CREATE

With a fader for each track and dedicated hardware buttons for the most used functions, you won’t need to menu dive to record your music.
