Currently, the Bitwig gate will produce an audible ugly stutter when the level of the incoming audio is around the threshold.
The Ableton Live noise gate provides a “return” knob. According to the manual:
“Return (also known as “hysteresis”) sets the difference between the level that opens the gate and the level that closes it. Higher hysteresis values reduce “chatter” caused by the gate rapidly opening and closing when the input signal is near the threshold level.”
For me, access to a control like this is the difference between a gate being usable and not being usable, and it seems like a relatively straightforward addition.
