JD-990's voice architecture includes "analog-like" parameters such as ring modulation, Frequency Cross Modulation (FXM) and oscillator sync. The JD-990 also incorporates 'structures' and can use any expansion boards or PCM cards created for the JV80 or JD800. Additional features include 6MB or ROM waveform data (expandable to 16MB) 24 voice polyphony and 8 part multitimbral capability 320x80 dot backlit LCD display 8 outputs configured as four stereo pairs and 2 space rack mount design. An on-board multiple effects processor can be used in both single or multi-timbral modes. A special super synth part can use up to 8 effects simultaneously, while other parts can use reverb, chorus and delay.
One of Liam's main sound sources for strings and stuff.
Liam uses this synth for almost every track in Jilted Genration album, and it can be heard at the beginning of Poison.
It was also used to the main riff on Voodoo People. There is also a preset sound called "EML Wobbler" that is used in ending of 3 Kilos.
Poison (the opening riff)
Voodoo People (the main riff)
"A year after selling my JD800, I did buy the JD990, which I think is really good. I've got all the expansion boards for it, but I don't use many of the analogue sounds off the vintage board -- it's mainly used for textures and strings. It's got a good distorted guitar, too. "
"I use the JD-990 on every track I do. I used it on the opening of Poison and everyone said 'Aw - where did you get that sound?' It was one of my own sounds that I modified. I used it on Voodoo People for the main riff."
