JD-990 is a multitimbral synthesizer utilising PCM sample-based synthesis technology. 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 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. 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.

Features

The JD-990 had the following features which were not available on the JD-800:

  1. Expanded wave ROM (6 MB vs. 3 MB)
  2. Ability to use an 8 MB expansion board from the SR-JV80 series
  3. JV-80 patch import
  4. 4 additional outputs
  5. True stereo engine
  6. Individual panning of each tone in a patch
  7. Oscillator sync
  8. Frequency cross-modulation (FXM)
  9. Matrix Modulation
  10. Modulation of the same destination from multiple sources
  11. Oscillator structures that allow ring modulation and serial dual filters
  12. Additional LFO waveforms: sine, trapezoid and chaos
  13. MIDI CC control of parameters
  14. Tempo sync delay
  15. Polyphonic portamento
  16. Analog Feel. Adds a very subtle pitch modulation to the basic waveforms intended to recreate an analogue synth's 'drift'
  17. Performance memories
  18. Additional multitimbral slots
  19. One patch can keep full effects in multi mode

Expandability

The JD-990 is compatible with the following:

  • The SR-JV80 series of expansion boards. The SR-JV80-04 Vintage Synth board includes 255 patches programmed specially for the JD-990.
  • The SL-JD80 series of waveform & patch cards released for the JD-800.
  • The SO-PCM1 series of waveform cards.
  • The JD9D series of patch cards developed specifically for the JD-990.

Factory Sounds

The Factory presets of the JD-990 were created by Eric Persing and Adrian Scott.

Notable users

The JD-990 has been used by artists such as Klaus Schulze, Paul Shaffer, Steve Duda, Vangelis, The Prodigy, Apollo 440, ATB, and Mirwais. On the Faithless song "Insomnia", the pizzicato hook is from a JD-990, with added reverb. Ronnie Martin from Joy Electric also used the JD-990 to synthesise every sound heard on the "We Are The Music Makers" album before moving onto more vintage synthesisers.
