Mute sound for just one second using drum pad

Hello.

I own a Novation Impulse midi keyboard and use it to play via Cantabile.

I was wondering if anyone knows if there is way to use the drum pad to mute a sound for just one sec or so. The idea is that I play a chord on the keys (to trigger a pad sound or similar), and while holding the chord, I tap on the drum pad to cut off the sound for a second.

Thanks,

Alan
