Roland JD-XA Analog/Digital Advanced Crossover Synthesizer

Analog. Digital. Magical.The JD-XA is a unique crossover synth that brings together analog warmth and digital versatility in one super-creative, no- compromise instrument. First, there’s a four-part, all-analog monster with true analog filters and a direct dry output. Next up is a four-part digital engine powered by Roland’s SuperNatural synth technology, plus an impressive selection of potent effects. The JD-XA’s engines can be used independently or interactively, providing an incredibly flexible platform for sound design, studio work, and live performance. Use the analog and digital parts side by side, stack them up for total sonic devastation, or shape digital waveforms via the analog filters to create sounds never heard before. With the JD-XA, you can forget about analog or digital—just close your eyes, imagine how the future sounds, and start creating music.

The Digital EngineThe JD-XA doesn’t just do classic analog—it’s also equipped with a completely separate four-part, 64-voice digital sound engine powered by Roland’s acclaimed SuperNatural synthesizer technology. This lets you play some of the most expressive and natural sounds available anywhere, as the JD-XA is compatible with the synth engine from the Integra-7 sound module, a firm favorite of top producers, composers, and sound designers. And if you need some extra inspiration, visit Roland’s online Axial community and download the latest creations from high-end programmers to tap into great sounds for a wide variety of genres.

The Digital EngineEach of the JD-XA’s four analog parts has two oscillators, along with filter and amp sections and four envelopes—all with incredibly fast attack and response times. You also get two LFOs, with super-smooth coverage from ultra-slow to ultra-fast. Start by creating your sound from scratch, or configure the JD-XA as an eight-oscillator, pure analog version of the legendary Supersaw waveform. Or invoke the power of Poly Stack mode for warm, organic four-note chords that will sweep you away. Once you’ve got that killer analog sound, you can route it directly to the analog dry output or send it to the onboard digital effects for further experiments in the art of sound design.
