JD 990

TheRoland JD-990Super JD is an updated version of theRoland JD-800synthesizer in the form of a module with expanded capabilities, which was released in 1993 by Roland Corporation. JD-990 is amultitimbralsynthesizer utilising PCMsample-based synthesistechnology.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 incompatible in exchanging presets. It is equipped with 6 MB of ROM containing sampled PCM waveforms, four sets of stereo outputs that are assignable to individual, internal, instruments, and standardMIDIin/out/through ports. JD-990 has a largeLCDdisplayand programming takes place through a keypad on the front panel of the unit. The unit can generate multi-timbral sounds reminiscent of the vintage analogue synthesizers but is also capable of generation of modern digital textures. There are several expansion boards available for JD-990 that can be installed in the provided expansion slot in the chassis of the unit.
