Working on New Sounds with the Roland JD-XI in a Two in One (Hybrid) Analog and Digital, it could be compared a bit to the Legendary JD-990 and JD-800, it has enough sound construction parameters as a Sequencer, also come enough Drum Kit, Additionally, the sound banks can be expanded by downloading patches from the Roland page, where there are 5 official libraries for this synthesizer and a lot of libraries and sound banks created by the user community.
But what I am most impressed with is the Vocoder, which surprises with its capacity, portability and ease of use.
