SP-404 MkII Stones Throw Edition Creative Sampler + Effector

DesktopDigitalPolyphonic

This limited-edition collab between Roland and Stones Throw Records drops you right into the heart of indie beat culture, complete with a high-shine aluminum faceplate etched with custom artwork by Jeff Jank, plus exclusive sound banks from artists like Kiefer, Sudan Archives, Mndsgn, J.Rocc, and DJ Harrison—each packing 16 patterns and 16 samples for instant inspiration.

At its core, it's a digital polyphonic sampler with 32 voices, 17 velocity-sensitive RGB pads that feel smooth and responsive with no-click action, and a vivid OLED display for zooming into waveforms, chopping samples, and tweaking effects on the fly. Load up to 160 samples per project from 16GB internal storage, capture audio via two stereo or one mono inputs (including dedicated mic/guitar processing with vocoder, auto-pitch, harmony, and anti-feedback), and output through stereo 1/4" jacks, dual headphone outs, or USB-C for phone streaming. Fire up SP classics like vinyl sim, cassette sim, DJFX looper, plus new lo-fi, resonator, reverb, and delay; layer them via bus FX routing, stretch time with VariPhrase, or hit DJ Mode to mix two channels with cue points and fader curves. Skip Back Sampling grabs the last 25-40 seconds of your performance automatically, and pattern chaining with Pad Link keeps sets flowing seamlessly—all in a super-portable 2.8" x 10.9" x 7.0" battery-powered body weighing just 2.4 lbs.

It ships with a collector's 7-inch vinyl featuring Kiefer and Mndsgn tracks built from their banks, plus J.Rocc's 30-minute cassette mixtape—perfect starters that the community has embraced for sparking fresh remixes and live sets. Producers love the workflow upgrades over earlier SPs, though some note the pads take a session to dial in for ultimate precision.
