Roland BT-1 Bar Percussion Trigger Pad
It can be used to trigger a V-Drums module or an SPD series percussion pad for a variety of functions including the start/stop of loops and tracks turning effects on and off kit selection and tap tempo functions. The BT-1 can be installed into your existing drum kit through a drum tension rod and the included attachment bolt spacer. It connects to your V-Drum module with the included stereo 1/4 connector. The BT-1 fits around a V-Drum pad or an acoustic drum and is designed to eliminate false triggering while playing the surrounding acoustic or electronic drums
