SP-404MKII vs MPC Sample vs EP-133 K.O. II: Which to Buy? (2026)

If you're shopping for a compact sampler that makes beats without a computer, the 2026 shortlist effectively comes down to three machines: the lo-fi scene's staple Roland SP-404MKII, the brand-new AKAI Professional MPC Sample (launched March 2026), and the calculator-styled hit Teenage Engineering EP-133 K.O. II.

All three are standalone units in roughly the $300–$450 street-price class, and the "which one is right" debate never stops on social media. And 2026 is the year the landscape actually shifted: the MPC Sample arrived, and the EP-133 doubled its sample memory to 128MB. Conclusions from older reviews no longer hold.

Based on each maker's official information and authorized-retailer listings as of July 20, 2026, this article compares the three on four axes — (1) lo-fi character, (2) portability, (3) beginner-friendliness, (4) expandability — and gives a verdict by user type.

Verdict first: the one-minute decision table

Official SP-404MKII introduction (RolandChannel). A good feel for the SP-side workflow.

1. The three characters at a glance

SP-404MKII = the "texture and performance" sampler

Released in 2021, it's still front and center thanks to firmware updates running through v5.5. With 41 multi-effects (Vinyl Simulator, Cassette Simulator, Lo-fi, Resonator, sidechain compression and more) triggered straight from the pads, it's the strongest of the three at "making sound dirty in a beautiful way." It adds OLED waveform editing, SKIP BACK SAMPLING (recover up to the last 40 seconds), a DJ mode, and native Serato and Koala Sampler integration. For a full review, see our "SP-404MKII review."

MPC Sample = the "MPC origin story," distilled to $399

Launched March 2026, this is the newest of the three. It condenses the pad-and-chop workflow that runs from the MPC60/3000 into a sampling-focused compact machine, dropping the touchscreen and expansion plugin instruments of its bigger siblings. You get 16 velocity- and aftertouch-sensitive RGB pads, an Instant Sample Chop mode, real-time timestretch and repitch, four FX engines — plus a built-in lithium-ion battery (about 5 hours), speaker and mic. No other unit here is this complete for "walk out with just the box, record on the spot, build on the spot." More in our "MPC Sample review."

EP-133 K.O. II = the serious sampler that plays like a toy

Teenage engineering's hit successor to the PO-33 K.O!. In 2026 it quietly switched to a new version with 128MB of sample memory — double the original — at the same price. Pressure-sensitive keys, a multifunctional fader, punch-in FX, built-in mic and speaker, all in a 16mm-thin slab. OS 2.5 added USB audio recording, reverse playback and more. Under the playful looks, it's a real instrument. Full review: "EP-133 K.O. II review."

3. Comparison 1: lo-fi and texture

If you're after the worn-tape texture of lo-fi hip hop and boom bap, the SP-404MKII is a clear head above. Vinyl Simulator, Cassette Simulator and the Lo-fi effect are synonymous with the SP series — the way these effects color sound has literally become part of the genre. Sidechain compression and stackable Bus FX give it the deepest sound-design well of the three.

The MPC Sample and EP-133 have effects too, but not this many, and not this texture-focused. Flip it around: if you enjoy the "chop the source, build the beat" stage more than effect sculpting, pick based on the next axes instead. To brush up the craft itself, see "how to make boom bap."

4. Comparison 2: portability and making beats outside

5. Comparison 3: beginner-friendliness

For first-time sampler owners, the real wall isn't the feature count — it's how visible the workflow is.

6. Comparison 4: expandability and longevity

This one is the SP-404MKII's home turf. 16GB of internal storage plus SD cards, a Mac/Windows editor app that also runs as an AU/VST3 plugin, native Serato DJ / Serato Studio and Koala Sampler integration, and a DJ mode — it's built to change roles from production to DJing to live sets and stay useful for years. Nearly five years of major firmware updates since launch back that up.

The MPC Sample expands via microSD and works as a doorway into AKAI's wider MPC ecosystem. The EP-133, with its 128MB of sample memory (2026 version), is deliberately constrained — treat it as a tool you play to the edges of. Constraints cut both ways: they limit you, and they get tracks finished fast.

7. Verdict: recommendations by type

Who the SP-404MKII suits

Who the MPC Sample suits

Who the EP-133 K.O. II suits

Any of the three delivers "sampling to finished beat, no computer." The fork in the road is texture (SP), self-containment (MPC Sample), or ease (EP-133). Picture the moment your production most often stalls, and buy the machine that removes it. Want to zoom out to pad workstations in general? See our "Maschine vs MPC comparison."

Frequently asked questions

Q1. Which is best for making lo-fi hip hop?

The SP-404MKII. It has the effects that define the beat-tape sound built in — Vinyl Simulator, Cassette Simulator, Lo-fi and more — and its track record in the lo-fi scene is unmatched. It is also on the cheaper end of the three at street prices (around $449-$499 in the US as of July 2026).

Q2. Can all three be used without a computer?

Yes. All three are standalone samplers that go from sampling to sequencing on the unit alone. The MPC Sample and EP-133 K.O. II have a built-in speaker and mic; for power, the SP-404MKII runs on six AA batteries or a mobile battery, the EP-133 on four AAA batteries or USB-C, and the MPC Sample on a built-in rechargeable lithium-ion battery lasting about 5 hours (official info as of July 2026).

Q3. How is the MPC Sample different from a regular MPC?

The MPC Sample is a compact machine focused purely on sampling. It keeps 16 velocity-sensitive MPC pads and a classic MPC-style sequencer, but drops the touchscreen and expansion plugin instruments of the higher-end models. In exchange it builds in a battery, speaker and mic, and keeps the price down to $399 (US, at its March 2026 launch).

Q4. Which should a complete beginner buy first?

For sheer ease of use, the EP-133 K.O. II is the strongest pick. Its gadget-like UI built around big pads and a fader teaches the sampling-to-song flow naturally. If you are planning to step up to MPCs or a DAW later, choose the MPC Sample; if you lean toward lo-fi textures or live performance, choose the SP-404MKII.

Summary

The 2026 compact-sampler debate is a three-way split: texture (SP-404MKII), self-containment (MPC Sample), ease (EP-133 K.O. II) — and whichever you choose, a computer-free beatmaking rig lands in the $300–$450 class. If you're still torn, scroll back to the decision table and answer honestly about how you actually work. After that, all that's left is to make beats and put them out. For checking sample BPM and key, use our free BPM/key detection tool.
