Creativity on the fly

It doesn’t always take a studio to spark musical creativity, because sources of inspiration for new grooves, beats, or instrumentals can be found just about everywhere. This is exactly where the compact SP-404MKII sampler from Roland comes in: Battery-powered and packed with massive internal storage and a pattern-based sequencer as well as all the necessary inputs for connecting a microphone, instruments, a laptop, and a pair of headphones, it is the ideal tool for recording loops on the fly and editing samples using auto chop and resampling directly afterwards. The SP-404MKII comes with a wide range of proven standard and lo-fi FX that allow genre-specific effects to be added to beats, and its smooth workflow ensures not only creative beat programming but also performances with just the right groove.

FX-powered groove sampler

This polyphonic sampler with 32 voices and 16GB of internal storage also allows additional samples and data to be stored externally on an SD card (sold separately) as well as new samples to be recorded via its microphone, guitar, and line inputs. All in all, the SP-404MKII offers music makers up to 16 projects comprising 160 samples each. The user-friendly sampler is equipped with 17 dynamic RGB-backlit pads for smooth pattern selection and a vivid OLED screen for easy sample editing and convenient handling even in poor lighting conditions. What is more, instant creative sound design is easier than ever thanks to the improved resampling function, and the range of effects makes a convincing case thanks to vinyl and cassette simulators, a resonator, and a DJFX looper. Special moments during a performance can be easily captured and resampled thanks to continuously active 40-second skip-back sampling.

Sample-based beat making

Grooves that are almost entirely made from samples are particularly popular in Hip Hop including all of its subgenres, but also in the Breakbeat, Minimal, and House scenes, where the SP-404SX and SP-404A predecessor models have been maintaining a loyal fan base for over 20 years. And although the new SP-404MKII comes with a software editor, which allows samples to be edited in even greater detail and projects or entire sample packs to be imported from the Roland Cloud, it has been specifically designed for those who prefer to work entirely or partly without a PC. And to stand out from the crowd visually, musicians can also personalise this sampler with their own customised skins.

About Roland

The Roland company was founded in 1972 in Osaka, Japan, and has been designing and building electronic musical instruments ever since. During its successful history, Roland has launched many ground-breaking instruments, from legendary drum machines such as the TR-808 and the TR-909 to synthesizer classics like Jupiter-8, SH-101 and the iconic TB-303. Besides synthesizers, Roland's workstations and electric pianos are also very popular. Equally well-known is Roland’s subsidiary Boss, under whose brand name it designs and sells principally guitar pedals and effects units. Under the Roland Professional A/V label, the company additionally develops and distributes professional equipment for virtually every branch of audio and video production - from home studios through to commercial applications.

Sampler or digital decks

The Roland SP-404MKII features an intuitive 4x4+1 pad grid that is perfect not only for launching and chaining drums, sample chops, and loops to create new dynamic grooves but also for finger drumming to add fresh beats. The included lo-fi FX allows individual samples or entire grooves to be edited and resampled with an authentic vintage sound and leaves more space for additional applications on the effects processor. Building a song step by step and creating entire tracks for a wide range of genres has never been easier, and the files can be seperately exported to a DAW. In the new alternative DJ mode, the SP-404MKII simulates two digital decks with all functions that are required for live DJing, such as two-channel mixing, cueing, synchronising, and editing. This makes the Roland SP-404MKII a powerful tool for artists who want to complement their live performances with an improvised mini DJ set.

SP404 MK2
Rob23 08.03.2022
This is a very capable machine, and it seems that Roland will continue updating firmware to make better and better.
This is my first hardware sampler and it is so much fun!
I'm still learning this beast but I can definatly recommend it for a range of uses. I sounds great with my bass plugged in for make like riffs and bass lines to work into a mix. it is also an excellent vocal processor, so can add effects to live voals in real time. I does seem a shame that I can't plug my bass and mic in at the same time but not really a deal breaker.
It comes into its own with chopping up altering and layering samples, this is what it is mostly built for and it does this very well.
I like that I can power it thru USB C and also connect to computer to sample direct from that and swap out and arrange samples thru the free MK2 software. The chromatic mode is very useful and there is lots of little things that I wish were different, but it is exciting that the instrument will shift and change with communities wishes an Rolands updates. Also a big plus for me learning this machine is that there is a very active youtube community that are eager to share their learnings and tips and tricks. So all in all if you are looking for a portable tool for composing, finger drumming, sampling and chopping as someone new to the game I am very satified, but note I don't have much experience with other hardware samplers


SP404 on steroids
Da Geek 10.12.2021
Same form factor as the mighty sp404, it packs lot of features. 4 more pads, better pads, velocity sensitive pads, oled display, sample chopping, more FXs, 1/4 jacks for input and output. Good quality for the price.


A Unique way to Sample
James Bermingham 12.10.2023
A super Roland Product. You will need to invest some time to it as it has a more advanced learning curve, with some button combination macros to master. But Roland have 2 fantastic Video manuals on YouTube to help with this process.

It has had a major firmware update in 2023 which adds more features that are explained in the update video on YouTube.

Amazing effects, Clearly Laid out Functions and sub-functions, Just the right size mini screen and there is also a companion Computer Application to easily transport files and projects in either direction.

A very creative sampler that can be combined with any electronic musical instrument or vocal.


been waiting forever roland !!!
abuse314 23.12.2021
my order came a month earlier than initially expected, well done thomann!
a worthy successor to the sp line. unlike the 404a, this seems like a well thought release and not a cash grab. its adding PITCH, envelope, an actually useful screen, new fx, quick chopping and others. the free updates gonna fix some minor workflow issues hopefully.
workflow seems a tad bit more tedious, being used to the 404og and its simplicity, as it was my only sampler for some years, but its a well worth trade for the features added and its still fun to use.
Sounds much cleaner and spacier/wider than the og. the fx are still in the same str8forward mindset, with more controls added, but also sounding different, which is good, 'coz i'm gonna keep my og which is the true classic, finding balance between speed-versatility-memory, quality- character.
