JD-800 Programmable synthesizer

Roland JD-800 oficial pictureFrom Roland Japan site: "Combining stunning digital sound and sophisticated digital technology with a natural feel and warmth reminiscent of analog instruments, the JD-800 was an instant sensation."


When the JD-800 appeared in 1991, Roland was the first to announce a new trend in the 90's: editability and overview. 

The JD-800 become instantly a megaclassical keyboard.

All sliders are dedicated editors just like the original analog synths. 

Based on sampling technology, it's a great synthesizer for guitar-like, analog bass or string/pad sounds. 

Internal ROM based with CD quality waveforms are combined to build sounds. 

This synth become the synth of choice in just about every studio around the world. 

It also can be used to control the JD-990 module.

This keyboard is an extremely programmable digital synthesizer that retailed for $3000 when it was first introduced. 

Units produced: 24.000 (source

From Roland Roland JD-800 Turbo facts:

  • SL-JD80 Series:
    A diverse library of Waveforms and Patches ranging from Acoustic, Dance and Rock drums to Strings, Brass, Pianos and even Accordian. Each set contains both a Waveform card and a Data card with 64 patches which utilize the sounds on the Waveform card.
  • SO-PCM Series:
    These cards contain new Waveforms for use with either the JV or JD-series synthesizers. The JD-800 can use these Waveforms to enhance its internal library and allow users to build new Patches.


These are the original Jd-800 sets. Each have two cards, one for patches and one with waveforms.

  • SL-JD80-01 Drums & Percussion STANDARD
  • SL-JD80-02 Drums & Percussion DANCE
  • SL-JD80-03 Rock Drums
  • SL-JD80-04 Strings Ensemble
  • SL-JD80-05 Brass Section
  • SL-JD80-06 Grand Piano
  • SL-JD80-07 Guitar Collection
  • SL-JD80-08 Accordion

The JD can use waveform PCM cards from JV series.


  • SO-PCM-01 Piano Selection 
  • SO-PCM-02 Guiter & Brass
  • SO-PCM-03 Rock Drums
  • SO-PCM-04 Grand Piano
  • SO-PCM-05 Accordion
  • SO-PCM-06 Baroque
  • SO-PCM-07 Orchestral FX
  • SO-PCM-08 Country/Folk/Bluegrass

Memory Cards

You can save memory data using standart M-256E cards or compatible as the M-512E. Note, using the M-512E won´t give  you double memory.

The cards save patch data, not waveforms.

  • Mix Out - Stereo (L/R)
  • Direct Out - Stereo (L/R)
  • MIDI in, Out, Thru; 
  • Sustain, Control pedal
  • Headphone,

  2. Ability to use a 8MB expansion board
  3. 4 additional outs
  4. True stereo engine
  5. Osc sync
  6. Cross-mod (FXM)
  7. Osc structures that allow ring mod and serial dual filters
  8. Additional LFO waveforms
  9. MIDI CC control of parameters
  10. Tempo-sync delay
  11. Polyphonic portamento
  12. Performance memories
  13. Additional multi-timbral slots
  14. One patch can keep full effects in multi mode
