The Roland JD-990 Super JD is an updated version of the Roland JD-800 synthesizer in the form of a module with expanded capabilities, which was released in 1993 by Roland Corporation. JD-990 is a multitimbral synthesizer utilising PCM sample-based synthesis technology. [1] In a sense it is not a true module version of a JD-800 as it has many expanded features and as a result the two are.. The JD-990 came out in kinda unlucky moment, jammed in between JD-800 release in 1991 and JV-1080 released in 1994 it somehow remained unnoticed by many. While those who have heard of it assumed it was just a module version of the JD-800. And because in 1994 we already had 1080 on the market, there was nothing to think about - go for the JV-1080!
