SP404 MK2 Almost 5 Years Later… Still Worth It?

If my SP404 MK2 broke today, would I buy it again?
After five years, countless firmware updates, and hundreds of beats made on this thing, the answer is a lot more complicated than it seems. The SP I’ve been using today isn’t the same machine I bought on day one. It’s not even the same as it was a couple of years ago.
Some parts have aged incredibly well. Some features only exist because of firmware updates. And there are still a few things that honestly drive me crazy every time I turn it on.
So, let’s get into it.
What Aged Well: The “Studio Chameleon”
The biggest reason the SP-404MKII is still on my desk five years later is simple: versatility.
I’ve always described it as a studio chameleon. It’s not necessarily the best at any one thing, but it can take on almost any role you throw at it. Need a sampler? It’s got you. Performance effects? Plenty. A looper or even a rough amp sim? It can handle that too.
Between pattern sequencing, DJ mode, long sample times, and live performance tools, it’s just as comfortable building beats as it is performing them.
More importantly, it’s a playable machine. Each pad can hold up to 16 minutes of audio, and with features like pad linking, mutes, chromatic mode, skip back recording, DJ mode, and the looper, it starts to feel less like a sampler and more like an instrument.
That flexibility is what has kept it at the center of my setup for years.
Firmware Changed Everything
Here’s the important part: a lot of what makes the SP404 MK2 great today wasn’t there at launch.
Core features like sample chopping and long sample times were always solid, but things like:
Chromatic mode
The looper
TR-REC sequencing
Additional effects
…all came later through updates.
Firmware didn’t just improve the SP, it fundamentally changed what it is.
One of the biggest shifts for me was chromatic mode. Suddenly, the SP wasn’t just triggering samples, it could actually be played like an instrument.
TR-REC mode helped bridge the gap between sample playback and sequencing. It’s not perfect, but it allows for quantization, step sequencing, ghost notes, and velocity changes in a way that wasn’t possible before.
The Looper: One of the Best Additions
If there’s one feature that completely changed how I use the SP, it’s the looper.
It’s not as deep as something like a dedicated loop station—you don’t get multiple independent layers—but it’s incredibly fast and fun to use. In fact, it’s one of the workflows I recommend most for beginners.
You can quickly layer sounds without even worrying about BPM. Just hit record, play something, hit record again, and it loops. The SP will approximate the tempo and keep things moving.
That immediacy makes it one of the fastest ways to get ideas down.
Skip Back Recording: Still Underrated
Another feature that’s been there from the beginning but remains incredibly useful is skip back recording.
If you’re jamming without recording, you can instantly capture the last 40 seconds of audio and turn it into a sample. It’s perfect for those moments where you stumble onto something great without planning it.
The Sound Generator (the SP's Hidden Power)
One of the more underrated additions is the sound generator, introduced in a later firmware update.
On the surface, it’s pretty basic: just raw waveforms and a monophonic synth. But once you start resampling, layering effects, and shaping sounds with envelopes, it becomes something much more powerful.
You can effectively build your own synth sounds entirely inside the SP.
Expanding the SP with External Tools
The SP has also benefited from better integration with external tools like Koala Sampler and Serato.
With Koala in particular, the combination is incredibly powerful. Each tool fills in the gaps of the other, creating a more complete workflow overall. All it takes is a USB-C connection, and you’re up and running.
This kind of integration helps push the SP beyond its limitations.
Where the Cracks Start to Show
For everything the SP does well, there are still some frustrations.
The biggest one is the workflow complexity.
The SP rewards muscle memory... but it punishes forgetfulness. Almost everything is tied to button combinations. If you forget how to access something, you’re either digging through menus or heading to YouTube to relearn it.
For example, muting pads in pattern mode requires a specific button combo. Keeping that mode active requires another. Features like groove settings are powerful, but buried in menus that aren’t always intuitive.
Once you know the shortcuts, the SP opens up. But getting there takes time.
Missing Features (and What’s Improved)
There are also a few features the community has wanted for a while.
At the time of recording, sidechain compression was still missing—but Roland has since announced it in a firmware update, which is a big step forward.
Other things, like per-pad filters, would make a huge difference for mixing. Being able to clean up low-end frequencies on individual sounds would improve clarity significantly.
Sequencing Still Lags Behind
The biggest limitation, in my opinion, is still sequencing.
TR-REC mode works, and I use it regularly, but it doesn’t compete with something like the Roland P-6 or Elektron Digitakt. Those devices offer deep step sequencing with parameter locks on a per-step basis, which gives you far more control.
The SP feels more like it adapted sequencing over time, rather than being built around it from the start.
Multi-Track Audio: A Missing Piece
Another limitation is the lack of multi-track audio over USB.
Modern hardware often allows you to send individual tracks into a DAW separately. The SP doesn’t really do this, which limits flexibility when mixing later.
There are workarounds—like using stem splitting in a DAW—but they’re not perfect. You can get decent separation, but it’s not as clean or controllable as true multi-track output.
So… Is It Still Worth It?
This brings us back to the original question.
If my SP-404MKII broke today, would I buy another one?
Yes.
Not because it’s perfect, but because there’s nothing else that does all of this in one box at this price point. It’s not the best sampler, the best sequencer, or the best looper... but it does all of those things well enough, and more importantly, in a way that just clicks.
That’s why it’s still at the center of my setup.
