The Roland SP-404A Linear Wave Sampler gives your Roland AIRA TR-8 Rhythm Performer even greater power, integrating seamlessly to expand your performance potential. For those who crave tactile control alongside powerful sampling, exquisite DSP effects designed to exceed the demands of any professional, the SP-404A is the stuff of dreams. Plus, the included SD card boasts a library of stereo samples, effects, and one-shots from the team at Loopmasters.

Awesome sampling and sequencing

The SP-404A communicates harmoniously with the TR-8 via MIDI cable, enabling you to weave together samples and patterns to your own unique flavour. The TR-8 can be used to trigger a sample on the SP-404A, play a sound on the TR-8, or both.

The SP-404A's stereo output can be connected to the TR-8's external audio output, enabling you to use the TR-8's powerful built-in functions to manipulate your samples in perfect sync. The TR-8's Side Chain function enables a simple pattern that has been programmed in TR-REC Mode to be ducked and gated to your heart's content.

Sampling on-the-fly

The SP-404A Linear Wave Sampler is equipped with a built-in microphone, which allows you to record whenever inspiration strikes. Thanks to battery operation via six AA batteries, you don't even have to worry about being in the studio, you can capture that sound anywhere! As well as the built-in mic, a mic input allows samples to be captured using an external microphone. Line inputs enable direct sampling from an external sound source, and you can rest assured that your samples will sound impeccable, thanks to the uncompressed WAV audio-capture format.

Tactile performance

The Roland SP-404A features buttons, knobs, and pads for every possible function, giving you total tactile control over the unit. The non-slip knobs, rubber trigger pads, and Sub Pad all respond with absolute precision, which is essential for capturing dynamic performances. Every pad is illuminated clearly, which the bright LED screen ensures clear visibility on the darkest of stages and in the most inhospitable of DJ booths.

"Sounds by Loopmasters"

The Roland SP-404A is home to nine banks of premium samples that get you up and running with looping from the start. The included SD card boasts a sound library of stereo samples, effects, and one-shots carefully crafted by the legendary crew at Loopmasters. The built-in SD card slot supports SDHC card sizes up to 32GB, enabling you to import WAV or AIFF audio files from either Mac or Windows-based systems using Roland's dedicated software. These can them be assigned to any of the SP-404A's pads.

Exceptional effects

Everything you need to lovingly shape your sounds as you wish lies within the SP-404A, ready and waiting to be explored. There are 29 onboard DSP effects that range from reverbs and choruses to filters and delays, each one designed to studio-grade quality and enhanced for live performance - including a voice transformer and looper. Get a mixer involved and you've got a fully-fledged standalone effects processor to play with. Thanks to a unique "limiter" mode, you can rest assured that unwanted noise will be supressed to preserve the quality of your performance.

The Roland SP-404A Linear Wave Sampler is endowed with an enviable looper, which allows you to construct songs, jams, and tracks in seconds. The Quantize mode offers shuffle to give your tracks a sense of freedom, whilst keeping everything on the beat and in the groove. You can store 120 patterns (12 patterns x 10 banks) to be recalled instantly, allowing you to plan sets in the studio, honing them meticulously, and improvising as and when the moment takes you.

Reliable Roland quality

As ever, the team at Roland have gone above and beyond to guarantee that no matter what you throw at the SP-404A, it is a hardy workhorse that is ready for anything. Not only that, but thanks to the matching finish, it slots perfectly into your setup alongside existing AIRA gear.
