The Roland JD-990 Super JD is a module version of Roland JD-800 synthesizer with expanded capabilities, which was released in 1993. JD-990 is a multitimbral synthesizer utilizing ‘wave-table’ sample-based synthesis technology. It is equipped with 6 MB of ROM containing wave-table, four sets of stereo outputs that are assignable to individual, internal, instruments, and standard MIDI in/out/through ports. JD-990 has a large LCD display and programming takes place through a keypad on the front panel of the unit.
