The parameters for the Gate section are:
CV Inputs
On the back of the RV7000 you find three CV inputs. These are:

Description
Threshold When Trig Source is set to “Audio”, this determines the audio sig-
nal level at which the gate opens. If you raise this setting, only very
loud sounds will open the gate.
Decay Mod This modulates the reverb Decay parameter so that the decay time
is lowered when the gate closes. When this is set to zero, no de-
cay modulation happens - this means that if the gate is closed and
then opened again, you may hear “previous” reverb tails that are
still ringing. If you raise the Decay Mod setting, the decay will auto-
matically be lowered when the gate is closed, eliminating this ef-
fect.
Trig Source Determines whether the gate should be triggered by audio or
MIDI/CV, as described above.
High Pass A high-pass filter that affects the audio that triggers the gate (only
active when Trig Source is set to “Audio”). If you raise this setting,
sounds with low frequencies only will not open the gate. Note that
this setting doesn’t affect the sound of the reverb, only the trigger-
ing mechanism.
Attack Determines how long it takes for the gate to open after a triggering
signal has been received.
Hold This parameter is only active when Trig Source is set to “Audio”.
Hold affects how quickly the gate closes, in the following way:
Internally, the gate is controlled by an envelope follower that ana-
lyzes the source signal level and generates a “level CV signal” ac-
cordingly. This signal is compared to the Threshold level to
determine whether the gate should be opened or closed. The
Hold parameter affects how quickly the envelope follower re-
sponds when the source signal level drops - you could say that
this is the decay control for the envelope follower. The higher the
Hold setting, the longer it will take for the envelope follower signal
to drop below the threshold level and close the gate. But the re-
sulting time also depends on the source signal level - with a loud
signal, it will take longer time for the envelope follower to drop to
the threshold level. Therefore, the actual gate time depends both
on the Hold setting and on the character of the source audio.
Release Determines how long it takes for the gate to close after the Hold
time.

Description
Decay Controls the reverb decay or echo/delay feedback via CV.
HF Damp Controls the HF Damp parameter on the main panel.
Gate Trig Used for triggering the Gate section with a gate signal. The length
of the gate signal determines the length of the gated reverb.
