Description | The JD-800 is Roland's answer to half a decade of hard-to-program synthesizers. Covered in sliders that act as dedicated editors just like a classic analog synth, the JD-800 is an extremely programmable and hands-on digital synthesizer. It is also an interesting and great sounding digital synth with incredible flexibility and control. Internal ROM based waveforms are combined to build your sounds. The sounds are based on Roland's D-50, but updated for the nineties with multimode filters - uncommon but welcome at the time.
The JD-800 came in a tough metal case capped off on the sides with large plastic covers. Programming may be a little too flexible for some users, but once you know what you're doing with it, almost any sound you can dream up can be dialed in and stored.
The JD-800 is a digital synthesizer that uses leading-edge digital technology in conjunction with Roland’s analog synthesizer expertise. Some of its main features are as follows. High-quality sound source The JD-800 uses a PCM sound source which contains 108 different types of PCM waveforms including sawtooth waves, pulse waves, noise waveforms, one~shot waveforms, and looped waveforms. Additional waveforms can be loaded from a WAVEFORM card (SO—JD80 series; separately sold).
Furthermore, these PCM waveforms can be processed by filters to provide an extremely wide variety of sound-creation possibilities. Front panel design for intuitive sound creation The JD—800 provides front panel controls for all basic Tone parameters, bringing an analog type interface to a digital synthesizer. Since parameter controls are arranged in the order of signal flow, the sound shaping process is easy to understand. You can also adjust the sound parameters in realtime as you perform.
On—board effects processor The JD-800 has an on-board DSP (Digital Signal Processor) that provides a wide variety of effects. in Single mode, you have eight different digital effects; a three-band equalizer for each Patch, and also distortion, enhancer, phaser, spectrum, delay, chorus, and reverb.
ln Multi mode, you have four different digital effects; a three-band equalizer for each Patch, and also chorus, delay, and reverb. You can specify how the effect will be applied to each of the five Parts and the Special Part. Two play modes ; Single and Multi The JD‘800 has two play modes; Single and Multi. ln Single mode, the entire JD-800 plays a single Patch. This mode is appropriate when you are playing solo parts.
In Multi mode, the JD-800 functions as a multi-timbral sound source with five Synth Parts and a Special Part. When used with a sequencer or MTR, this mode allows the JD-800 to simultaneously play all the parts of an ensemble.
External expansion The JD-800 has two card slots; DATA card (M-256E, sold separately) and WAVEFORM card (SO-JD80 series, sold separately). When a DATA card is inserted, you can select from a total of 128 Patches, including the 64 internal Patches. If a WAVEFORM card is used, you can also create sounds using PCM waveforms from the card.
