Roland SP-404MKII Creative Sampler and Effector

Roland SP-404MKII Creative Sampler and Effector - Portable Beatmaking Powerhouse with 16GB Storage & Vivid OLED Display

The Roland SP-404MKII is the ultimate evolution of the legendary SP sampler series, delivering faster, more expressive beatmaking and live performance capabilities in a compact, ultra-portable design. Loved by beatmakers worldwide for its rapid workflow and signature sound, this creative sampler and effector now features a vivid OLED display, 17 velocity-sensitive RGB pads with a smooth no-click design, and expanded 16 GB internal storage that holds massive sample libraries and patterns. Whether you're producing in the studio, performing live, or sketching ideas on the go, the SP-404MKII gives you everything you need to capture, chop, sequence, and twist sounds instantly with professional results.

Build beats lightning-fast with 32-voice polyphony, real-time sampling up to 16 minutes per sample, and powerful editing tools including real-time or auto-chop slicing, waveform zoom, envelope shaping, pitch shift, and resampling. The intuitive pattern sequencer supports real-time loop recording and TR-REC step sequencing with adjustable quantize, shuffle, and Groove Function for natural swing. Unique features like Skip Back Sampling (capturing the last 40 seconds of audio) and Loop Capture let you never miss a creative moment, while the onboard Sound Generator adds mono synth tones, basslines, and melodic phrases directly inside the unit.

Shape your sound with 41 multi-effects including classic SP favorites like Vinyl Simulator and DJFX Looper, plus fresh additions such as Lo-fi, Cassette Simulator, and Resonator. Layer effects via Bus FX with motion recording, and use dedicated input effects for mic or guitar including Vocoder, Auto Pitch, Harmony, and Guitar Amp Simulator. Connect seamlessly with USB-C audio/MIDI, MIDI gear, or mobile devices for streaming and collaboration. The SP-404MKII also integrates beautifully with Serato DJ software and the Koala Sampler app, blurring the lines between hardware beatmaking and digital DJing while remaining fully standalone and battery-powered for true portability.
