    The combination of this fast rising edge, and the silence which follows the gated signal, creates a dramatic improvement to the original signal. Drawmer pioneered the frequency conscious gating common to many noise gate clones now available in audio processing equipment. The MX40 has a new spin on this feature where both controls have been amalgamated into a single intuitive control, of course with a Key Listen facility.
