BD-808 and BD-909, modelled after the bass sounds of the Roland TR-808 and TR-909, are two freeware kick drum generators plugins for PC and Mac (VST/AU).


The Synsonic BD-909 is a model of the TR-909 Bass Drum.

The plugin includes factory presets and you can also create your own presets now.

  • Decay: Duration of the drum sound
