X904

• Authentic VCA gate and expander plugin
• Fast and precise transient response
• Adaptive release and sidechain filter options
• Ideal for drums, guitars, and live sound applications
• Recreation of a classic 1980s dynamics module

The X904 delivers fast and transparent gating to clean up drum recordings, remove noise, or add rhythmic precision to performances. Its VCA-based design ensures lightning-fast response and smooth transition between open and closed states, maintaining the natural transients of the original sound. 
 
With switchable sidechain filtering and an adaptive release mode, X904 goes beyond traditional gating—making it a creative sound-shaping tool as well as a surgical noise suppressor. 

Based on the hardware module that complemented the 902 and 903 units, the original gate/expander from the 1980s became essential in drum mixing and live sound engineering. We carefully measured a preserved unit to bring its iconic snappiness and musical envelope control into the Synergy Core Native world.
