The Gate section The Gate section allows you to create gated reverb effects with a lot of options and possibilities. You can either trigger the gate from the source audio signal or via MIDI or CV. When triggering the gate from the source audio signal, it works like this: • The gate “listens” to the source (dry) signal and opens whenever the signal reaches a certain threshold level. • The reverb sound is sent through the gate - when the gate is closed you won’t hear the reverb. • When the source signal level drops below the threshold level, the gate closes after a time that depends on the Hold parameter and the level of the source signal (see the parameter table). If you need the gate to be open for an exact duration (time), you should trigger it via MIDI or CV. In audio trigger mode, the actual gate time will vary depending on the source signal. When triggering the gate via MIDI or CV, it works like this: • The reverb sound is sent through the gate - when the gate is closed you won’t hear the reverb. • Whenever the gate receives any MIDI note (sent to the RV7000 Mk II) or a gate signal (connected to the Gate Trig CV input on the back of the RV7000 Mk II), the gate opens for the duration of the note or gate signal. Note: To activate the Gate, click the Gate Enable button on the main panel so that the indicator lights up. To make Gate settings, select “Gate” with the Edit Mode button to the left in the remote programmer panel. In this mode, the remote programmer display shows two meters - one showing the signal level (with an indication of the threshold level) and one showing the status of the gate. This is useful for checking what happens, how the gate triggers, etc. The parameters for the Gate section are: | Parameter | 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 generates 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 signal 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 character of the source audio. Release Determines how long it takes for the gate to close after the Hold time.
