ROLAND JD-990 TURBO FACTS
The JD-990 Super JD is one of Roland's most powerful and programmable synthesizers.
It features 6 Mb of our highest quality 44.1kHz waveforms, a powerful and flexible synthesizer
architecture with extensive real-time control, 4 pairs of stereo outputs, and a dynamic
multi-effects processor for creating stunning synth textures, as wellas expressive acoustic instruments.

Initializing

To return the Super JD to its factory setup:

  1. Hold EXIT and press UTILITY.
  2. Press F6 EXECUTE.

ROM Demo

To play the Super JD's demo songs:

  1. Press EXIT and CURSOR DOWN simultaneously.
  2. Press F5 START to play the chain of songs. Or, CURSOR DOWN to any of the songs and press F5 START.

Selecting Patches

The Super JD features 192 Patches -- 128 Preset Patches (A/B), and 64 User Patches (I). An M-256E card can hold an additional 64 User Patches (C).

  1. Press PATCH.
  2. Press A, B, or INT to select a Patch bank.
  3. Use the VALUE dial to select new Patches.
  4. Press the VALUE dial to open a window of the current Patch bank.
  5. Use the VALUE dial, or use the cursors, to move among the Patches.
  6. Press the VALUE dial again to move to the next patch bank.
Using Controllers with Patches

Most of the Patches in the Internal Bank are setup to respond to controllers "4 "and "1" or "11" for real- time control of various parameters. Use a controller keyboard or sequencer that can transmit one or both of these controllers to shape the sound of the JD-990 Tones in real-time.

Patch I-11 DeepSEAmphony is a good example of how these controllers can be used. Controllers can be assigned to control a wide range of parameters including pitch, cutoff, resonance, level, and LFOs. Two controllers can be assigned for each Tone.

Editing Patch Parameters

The JD-990 features extensive Patch editing capabilities. In the Patch mode, you can easily move to these parameters using the F keys.

  1. Press F5 LFO & CTL.
  2. Press F5 to toggle between individual Tone view and Palette view. For now go to Tone view.
  3. Press F2 LFO1. The LFO structure is displayed for the active Tone.
  4. Cursor to each parameter and use the VALUE dial to change the values. The graphic display shows your changes as you make them.
  5. Use the F keys to select other parameters and their graphic displays.
Sequencing

The Super JD is 8-part multitimbral in Performance mode. To quickly get started sequencing with the Super JD, choose one of the Preset Performances B-09 through B-16. These Performances are already configured for multitimbral setup on channels 1-7 with Rhythm on 10.

  1. Press PERFORM.
  2. Press B.
  3. Press the VALUE dial until the bank of Performances Pop Kit through Ethnic Kit appears.
  4. Select a Performance for sequencing.

To select sounds, levels, panning and other parameters for each Part:

  1. Press F2 PART.
  2. Press F6 Palette.
  3. Cursor to your desired parameter.
  4. Use the VALUE dial or INC/DEC buttons to make your changes.
Using Expansion Boards & PCM Cards

The Super JD's 6 Mb of memory can be user-expanded to 16 Mb using the SR-JV80 Series Expansion Boards, and SO-JD80 and SO-PCM1 Waveform Cards. Both the SR-JV80 Boards and SO-PCM1 Cards also contain Patches. These Patches must be loaded into User Memory locations before they can be played normally.

  1. Install the Expansion Board, or insert an SO-PCM1 Card.
  2. Press PATCH.
  3. Press UTILITY.
  4. Press F4 CARD.
  5. Press F5 LD PRM.
  6. Use the Data Wheel to select either PCM Card or EXP Board.
  7. Cursor to the right, and use the Data Wheel to select a Patch.
  8. Press F6 EXECUTE.

The Patch is now in temporary memory. You can use the WRITE procedure (UTILITY, F1) to store it in any User Patch location.

Using the Effects

An integral part of the Super JD's sound is its tremendous multi-effects processor. Any Patch can use up to 8 effects at one time. The effects are divided in to two Groups, A and B. Group A includes Distortion, Phaser, Spectrum EQ, and an Enhancer. Group B features Chorus, a Stereo Multi-Tap Delay, and Reverb. The delay has been expanded to 3000ms, and will sync to MIDI clock. Two effect Parameters can be controlled in real-time via MIDI.

To setup Effect control via MIDI:

  1. Press PATCH.
  2. Select PATCH I-15 DistSynChorus.
  3. Press EFFECTS.
  4. Press F2 FX Control.
  5. Choose your control Source. This is the controller you will transmit from your keyboard or sequencer.
  6. Choose a Destination for your controller.
  7. Set the desired depth of effect.

Note: Your destination Effect must be enabled under F4 Group A and F5 Group B.

Assigning Outputs

The JD-990 has four pairs of stereo outputs to which any of the eight multitimbral parts can be assigned in Performance mode. By panning a Part all the way to the left or the right, you can effectively assign each Part to its own output.

To assign a Part to a Stereo Pair:

  1. Press PERFORM.
  2. Press F4 Out & FX.
  3. Cursor down to bottom row.
  4. Cursor left or right to the desired Part.
  5. Turn dial to select D-1, D-2 or D-3.

    Now pan the Part hard right or left within the stereo pair for individual outputs.

  6. Press F2 (Part).
  7. Press F6 Palette.
  8. Cursor to Pan for the desired Part.
  9. Dial to L50 for "hard left" or R50 for "hard right".

If you are using a stereo Patch, each Tone must be panned to the center for these settings to take effect. From the Patch mode, press F4, cursor to Pan, and set all 4 Tones to "0".

Using the Oscillator Sync Function

This function lets you create interesting effects by forcing any waveform to be "slaved" to any other waveform in a Patch. Any Tone (waveform) within a Patch can be designated the "master." Each remaining Tone can then be slaved to the frequency of the "master". Pitch envelopes can be applied to the "slave" Tone(s) to try to force them out of tune, creating new harmonics and resulting in the characteristic Sync sound. This effect only works when Solo is ON. Also, the Tone switch for the selected Master Tone must be turned ON.

  1. In Patch Play mode, select a Patch to edit.
  2. Press F1 COMMON.
  3. Press F2 Key FX.
  4. Press CURSOR DOWN to Switch.
  5. Use the VALUE dial to turn SOLO Switch ON.
  6. Press CURSOR DOWN to Sync Master.
  7. Use the VALUE dial to select a master Tone.
  8. Press EXIT.
  9. Press F2 WG.
  10. Press F1 Wave.
  11. Press CURSOR DOWN to Sync Slave SW.
  12. Press TONE SELECT to select a Slave Tone. 1
  13. Use the VALUE dial to turn the Sync Slave Switch ON. 1
  14. Repeat steps 10 and 11 for the remaining Tones as desired. 1
  15. Press EXIT.
Use a JD-800 to edit Patches

Each of the edit sliders on the front panel of the JD-800 can be used to edit the Tones in the JD-990 in real-time.

  1. Press SYSTEM.
  2. Press F4 RX MIDI.
  3. CURSOR to RX EXCLUSIVE.
  4. Use the VALUE dial to select ON-2.
  5. Turn on the TX EDIT function in the JD-800 MIDI Menu.
  6. Use the edit Sliders on the JD-800 to alter the JD-990 Tones in real-time.

If the appropriate edit window is open in the JD-990, the graphic display will show your changes as you make them. Make sure the correct Tone Switch is enabled for the parameter you are editing.
