# Roland SP-404

The Roland SP-404 Sampling Workstation is a sampler made by Roland Corporation. Released in 2005, it is part of the SP family and successor to where Boss Corporation’s SP-505 sampler left off. The sampler was succeeded by the SP-555 in 2008, but was later given its own upgrade as the Roland SP-404SX Linear Wave Sampler in 2009. Another upgrade, the Roland SP-404A Linear Wave Sampler, was released in 2017. A third upgrade, the SP-404MKII was released in 2021. The Roland SP-404 has played a huge role in influencing the sound of popular Hip Hop subgenre known as Lofi HipHop.

### OG / SX / A

Having the traditional features of the Roland Grooveboxes, the 404 has the ability to record audio directly via line/mic, or import/export industry-standard WAV and AIF files via CompactFlash card. An onboard pattern sequencer allows up to 8,000 notes to be recorded in real time.
Pattern data can be quantized and up to 24 patterns, each 1–99 measures long, can be stored in the internal memory. Using a 1GB CompactFlash card, sampling times can be as long as approximately 772 minutes in Lo-Fi mode, or up to 386 minutes long in Standard mode.
However, the 404 (along with its own upgrades) lacks the D-Beam feature of the previous SP-808 and SP-606 installments. Although the first bank comes with preset samples that are protected, these samples can be removed by holding "cancel" as you turn it on. This allows you to delete the samples from the protected bank.
The release of the 404SX in 2009 introduced the change from CompactFlash cards to SD cards, along with additional features, faster processing and changes to the in-built quantization system. The 404A introduced cross-compatibility with the Roland TR-8.

### MKII

Released in 2021, the 404MKII was a significant upgrade, while retaining the unit's original form factor. Among the new features were an OLED display capable of showing sample waveforms, 16 GB of internal memory, USB-C and 32-note polyphony. The device was also given a new "Skip Back Sampling" feature with the addition of a "Mark" Button. This feature provides users the option to record the most recent 40 seconds of usage with the press of the button.
