Standalone is the whole point. Unlike a MIDI controller, these samplers record, chop, sequence and play back audio on their own — no computer in the signal path. The MPC Sample and the SP-404MKII even run on batteries, so a beat can start in a coffee shop and finish in the studio. Ask yourself how often you will actually use it away from a desk before you pay extra for battery power.
Pads, screen and workflow decide how fast you work. The 16 velocity-sensitive MPC pads on the MPC Sample and MPC One G2 are the reason finger drumming became a genre. The SP-404MKII's 16 pads drive the classic SP chop-and-resample workflow that lo-fi producers swear by. If you mostly sequence from a menu, the Digitakt II's button-and-knob approach is deeper but slower to learn.
Storage and connectivity gate your workflow. The MPC Sample and Digitakt II use microSD cards, the SP-404MKII takes SD cards, and the MPC One G2 has 64GB internal plus SD and USB-C. If you sample from a phone or record out loud, check for built-in mic, line inputs and USB-C audio. These four all cover the essentials — the differences are power, price and how much you want to carry.
