James Woolley, former keyboardist for Nine Inch Nails, passed away at the age of 50 this past weekend. Consequence of Sound spotted a Facebook post from Woolley’s ex-wife, Kate Van Buren, sharing the news on Tuesday; the cause of death was not revealed.

Woolley played keyboards on Nine Inch Nails’ most famous album, 1994’s The Downward Spiral, during a three-year stint with the group. He also appeared in NIN’s 1997 concert documentary Closure.

“James played briefly in Rob Halford’s band Two, produced music for a wide array of groups, worked on sound design for The Simpsons (those fart sounds are authentic), and worked on his own tunes for his band VOID in our home studio,” Van Buren posted on Facebook. “Though our marriage ended, James always stayed close to his children. He loved being a father. Because of significant neck and spine injuries, he wasn’t capable of doing a lot of physical activities with them, but he loved sitting down to paint, or teach piano, or just look at nature. He passed his amazing musical and artistic talents to all three children.”
