Synths ⇝ Roland ⇝ Roland JD-990

The Roland JD-990 is the rackmount version of the Roland JD-800 with a few extras thrown in. It has 6 megabytes of ROM sounds (two more than the JD-800) and includes many effects including filter, ring modulator, cross-modulation, delay, reverb, phaser, distortion, chorus, and equalization.

It has a lot of expansion potential due to its support for both SL-JD80 expansion cards and the JV80 series of expansion boards.

The JD-990 is known to have been used by Apollo 440, Mirwais, and Prodigy.
