Zoom R4 MultiTrak 4-Track 32-Bit Float Multitrack Recorder

Zoom R4: A 32-Bit Float Four-Track for Song Ideas Anywhere

The Zoom R4 MultiTrak is a four-track 32-bit float multitrack recorder, sized for songwriters who want to catch an idea the moment it lands, wherever they are. Two XLR/TS combo inputs and a built-in mic mean a guitar, a vocal, or a quick room recording is one button away. At 287 grams it slips into a bag, yet it records real multitrack sessions in a format that cannot clip. It is the R-series recorder for the writer who works on the move.

Two Inputs, a Built-In Mic, and Faders

The two combo inputs take a mic and an instrument at once, so a verse and a guitar part go down together. The built-in microphone captures a hummed melody or a room idea without plugging anything in. Physical volume faders and a 2-inch color LCD keep balancing hands-on rather than buried in menus. A 3.5 mm stereo output feeds headphones or monitors for quick playback.

Stereo Bouncing Keeps Ideas Growing

Four tracks fill up fast when an arrangement takes shape, so the R4 lets you mix them and bounce down to a dedicated stereo track. That frees the original tracks to keep layering harmonies, overdubs, and parts. A sketch can grow into a full arrangement without ever leaving the device. For a writer chasing a fast-moving idea, that headroom matters more than raw track count.

Effects, Rhythms, and a USB Interface

Onboard effects and built-in rhythm patterns turn a bare idea into a demo with feel, no computer required. When it is time to move to a DAW, the R4 becomes a 2-in/2-out USB-C audio interface with 32-bit float, connecting to a computer or smartphone. Recording lands on microSD cards up to 1 TB, and power comes from four AA batteries or USB-C bus power. From first idea to DAW import, one small box carries the whole workflow.
