Roland SP-404SX Desktop Loop Sampler

Roland’s acclaimed SP-404 performance sampler takes an exciting leap forward with the new SP-404SX. In addition to the fun, fast, hands-on features of the original, the new model offers enhanced sound quality with pure 16-bit linear sampling, improved DSP effects, smooth FX switching, a more versatile pattern sequencer (with a new shuffle feature), and easier data management with SD-card compatibility. It’s a creatively stimulating, powerful tool for DJs, musicians, producers, and live-sound engineers who trigger jingles.

  • Sample anytime, anywhere with the built-in mic and battery power
  • 29 DSP effects, including filter, delay, unique voice effects, subsonic, and looper
  • 3 control knobs, 12 trigger pads, and Sub Pad for rapid repeat triggering
  • Seamless effects switching for smooth, perfect performance
  • pattern sequencer with quantize mode and new shuffle feels
  • 1GB SD card included; expand sample storage up to 32GB with SDHC
  • Import audio files from computer, assign samples to pads with bundled software (Mac/PC)

Start sampling right away with the included 1GB SD card. You can easily expand the sampling time using up to 32GB SDHC. Import audio files from your computer using the included software (Mac/PC) and assign them to the SP-404SX’s pads. WAV and AIFF files are accepted. The software is fast and easy to use, as it displays the SP-404SX’s pads onscreen. You can even use it to convert SP-404 format files to the SP-404SX.
