Roland's Portable Sample Workstation Is More Potent Than Ever

This article was Written By

Get to know them!

The Roland SP-404MKII Linear Wave Sampler is the most powerful incarnation of Roland's beloved sampling workstation ever devised. Dual headphone outputs streamline collaboration with other musicians without needing a mixer or separate headphone amplifier to monitor your sampling session. An updated resampling workflow makes it simple to re-record patterns and effects layers; plus, with a generous selection of new effects on top of classic SP effects, the sound design potential is vast. Factor in its OLED screen for visual sample editing, the ability to tap out edit points in real time, pattern sequencing to turn ideas into full performances, and native Serato integration, and it's clear the Roland SP-404MKII stands out as a leader among portable sampling workstations.

Pro tip: to better grasp the full creative potential of the SP-404MKII, check out Sweetwater's Knowledge Base article, Working with Projects and Samples on the Roland SP-404MKII.

Sample or stream to mobile devices via USB-C

Here's a first among portable sample workstations: the SP-404MKII is equipped with a USB-C port to connect to your mobile device. You can sample audio from mobile apps, videos you've recorded, or any other audio source from your device. You can also stream audio to your device directly from the SP-404MKII. Finally, the USB port allows you to connect with the SP App on your computer for sample editing and project management.

All the effects you need

Sample artists at Sweetwater have long been fans of the SP series' effects like Vinyl Simulation and DJFX Looper, and the SP-404MKII adds even more ear candy to the mix. Effects such as Lo-fi, Cassette Simulation, and Resonator expand your creative potential, and the Mic/Guitar input can tap into Vocoder, Auto-Tune, and Guitar Amp Simulator effects. And thanks to the SP-404MKII's updated resampling workflow, it's faster than ever to process audio through effects and bring the resampled audio into your arrangement.

DJ mode encourages live performance

Gigging electronic musicians who typically juggle two SP sampling workstations will rejoice at the SP-404MKII's new DJ mode. It offers an all-new approach for live performance, allowing you to manipulate and mix two audio files with eight pad controllers per side. Speaking of live performance, the SP-404MKII allows you to chain patterns together manually, save a sequence of patterns chained together for playback, or even link up to four pads to be triggered by a single pad.

The ultimate SP — now a Serato controller too!

Since its release in 2021, the SP-404MKII has been the tool of choice for performance-based beatmakers and creative musicians. Now, with version 5, this sampler workstation offers seamless integration with premier software tools in DJ and beat culture, including native support for Serato DJ Lite, Serato DJ Pro, and Serato Studio. This enables you to use the SP-404MKII as a pre-mapped Serato controller, paving the way for innovative DJ sets, beatmaking, and song creation. Additionally, you can combine Serato’s advanced audio processing with the SP-404MKII’s intuitive interface, fusing the creative power of Serato Stems technology with the expressive capabilities of Roland’s acclaimed SP effects.

The SP-404MKII’s version 5 update also includes potent bug fixes and several user-requested enhancements, such as displaying the current setting during resampling and allowing you to trigger the start of the resample with the Sound Generator, which can now be accessed when resampling is restarted. Moreover, MIDI CC transmission is assigned to the unit’s CTRL knobs, and Skip Back Sampling can now be performed while in DJ mode.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
