The Roland JD-Xi is a unique breed: it's a hybridization of digital and analog. Though it's small, the JD-Xi packs an analog synth section that's perfect for leads, two separate sections for digital synths totaling 128 voices in all, a vocoder, a four-track pattern sequencer that allows you to jam over loops, and even a library of preset sounds into its small enclosure. Impressively, that's not all this tiny hybrid synth holds, but you'll have to grab one and play it for yourself to find out just how many features the JD-Xi has.
