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 signal 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 decay 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 automatically be lowered when the gate is closed, eliminating this effect.
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 triggering 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 analyzes the source signal level and gen-
erates a “level CV signal” accordingly. 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 responds 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 sig-
nal to drop below the threshold level and close the gate. But the resulting 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 charac-
ter 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.
