Roland JD-XA - Crossover Synthesizer
The JD-XA crossover synthesizer lets you blend analog and digital engines together to create completely new sounds, or you can use both engines independent of one another, giving you two synths in one.
The analog engine features 4 discrete sections, each with 2 oscillators, filter and amp sections and 4 envelopes. With fast attack and super-smooth LFOs, the JD-XA gives you beastly sounds in an ultra-programable package. Create up to 4-note chords—100% analog, 100% warm, smooth and punchy—and send them through the analog dry output or a selection of onboard digital effects.
And that’s just the analog side. An independent, 4-part, 64-voice digital engine is powered by Roland's SuperNATURAL technology. The JD-XA also lets you create natural, expressive sounds—or combine the analog and digital synth engines and functions to create entirely new sounds of your own.
