Designed for live use, the SP-404A Linear Wave Sampler expands the sounds of the Roland AIRA TR-8 Rhythm Performer for a powerful combination of sample and percussive synthesis. The fast, hands-on approach of the acclaimed SP-series performance samplers is a perfect fit for the impressive rhythmic effects and iconic step-sequencer of the Roland AIRA TR-8.

All of the functions and features of the popular SP-404SX are contained in the SP-404A, including its distinctive 16-bit linear sampling, 29 onboard DSP effects, smooth FX switching, and 12 professional performance pads. Plus, a new library of sounds curated by sample-industry leader Loopmasters are provided via the included SD card.

TR Sequencer Meets SP-Style Sampling
The SP-404A can be triggered from the TR-8 Rhythm Performer for powerful, integrated beat and sample production. Simply connecting a MIDI cable between the two gives you the ability to incorporate samples from the SP-404A and use them in conjunction with your drum patterns. Each of the TR-8’s 11 tracks can trigger a sample on the SP-404A, play a TR-8 sound, or both, enabling you to create interesting layers and accents. 

Sample Scatter and Side Chain
By connecting the stereo output of the SP-404A to the TR-8’s external audio input, you can use the TR-8 as a sub-mixer and processor for the sampler. In this configuration, all samples played on the SP-404A can be effected using the powerful TR-8 Scatter feature to reverse, glitch, gate, truncate, stutter, and perform all manner of rhythmic variations from subtle to extreme, and all in perfect sync. 

Instant Sampling
Sampling is not limited to the studio with the SP-404A. The built-in microphone allows for simple recording anytime and anywhere inspiration may strike, powered by AC or six AA batteries. Line inputs enable direct sampling from a mixer or external device, and a mic input is also available for sampling with an external microphone.

Extreme Effects
Your signature sounds can be sculpted at any time via the SP-404A’s 29 onboard DSP effects. Essentials include spacious reverbs and choruses plus lush filters and delays, and all provide seamless switching for smooth transitions while performing. There are also striking, performance-based effects on hand, including a voice transformer and a looper.
