One Small Step For SP-Series Samplers, One Giant Leap For "Samplerkind"

The great features that users loved from the original SP-404 have carried over to the SP-404SX along with vastly improved sound quality, 16-bit linear sampling, enhanced onboard DSP effects, seamless FX switching, a far more versatile pattern sequencer (with a new shuffle feature) and much simpler data management thanks to the SD-card compatibility. The SP-404SX is certainly an inspiring tool for DJs, musicians, producers, and live sound engineers who trigger sound effects.

Instant Sampling
Sample anywhere, anytime using the SP-404SXs built-in microphone. And since the SP-404SX can run on AC or battery power (six AA batteries), its easy to record wherever and whenever inspiration strikes. Just power-up, point, and record. Line and mic inputs are also available for recording direct or with an external microphone. The SP-404SXs sampling format is uncompressed wave for high-quality audio capture.

Hands-On Performance
The SP-404SX is made to be played its packed with interactive controls for jamming along with loops and patterns. Put your fingers on the three non-slip control knobs, 12 trigger pads, and Sub Pad for rapid repeat triggering in real time. On dark stages or DJ booths, the SP-404SX is a performers dream with its illuminated rubber pads and bright LED screen.

Extreme Effects
Create a signature sound using the SP-404SXs 29 DSP effects, which switch seamlessly during live performance. Essential onboard effects include spacious reverbs and choruses, plus filters and delays. There are also unique, esoteric effects built in, including a voice transformer and looper. With the DJFX Looper, you can create short loops (such as machine-gun-like da-da-da-da-da sounds) and control reverse-playback with the knob. You can also create scratch effects like a turntable. Connect the SP-404SX to a DJ mixer and use it as an effect processor. Seventeen of the effects have a limiter mode, which keeps the effects from overloading. This is great for live DJ performance when you dont want to lose control of the effects in the heat of the moment.

In addition to the endless supply of loops you can pack into the SP-404SX, you can also create your own tracks in real time with the Pattern Sequencer, complete with quantize mode, which includes shuffle feels. Creating patterns is done in real time. You can loop two measures (maximum 99 measures), for example, then play and record only the bass drum and the snare. Next, add the hi-hat over the top, and keep adding more instruments while the SP-404SX loops. You can store 120 patterns (12 patterns x 10 banks). When you play a pattern with the Pattern Sequencer, the LEDs surrounding the display blink according to the tempo, which is handy during live performance.

SD Card Memory
Start sampling right away with the included 1GB SD card. You can easily expand the sampling time using up to 32GB SDHC. Import audio files from your computer using the included software (Mac/PC) and assign them to the SP-404SXs pads. WAV and AIFF files are accepted. The software is fast and easy to use, as it displays the SP-404SXs pads onscreen. You can even use it to convert SP-404 format files to the SP-404SX.

Beautiful object of great import

October 12, 2012

The Roland SP-404 is a great machine for making music and noise using samples. It also includes a great many effects to twist and crunch and otherwise change the sounds that you record into the pads. The pattern sequencer is awesome. There are a few drawbacks: no legit pitch-change system (the pitch changer makes sounds really dull and wavery-sounding), and you can only play 6 stereo or 12 mono samples at one time or else some of the samples cut out. Otherwise, it's a great entry-level device and a useful tool for the production of audio art.
