OSX: 10.7+ 64 bit VST, AAX, AU
Main Controls #
Adjusts the size of the emulated acoustic space from 1 cubic centimeter to 1 cubic kilometer. The space emulated in this reverb is multi-dimensional and does not represent a realistic structure.
Enables the control of reverb size, morph slots and decay stop via midi notes as indicated under the section “Midi Controls”.
This setting is saved per instance in a project, and is not a parameter.
Adjusts the decay of the reverb from 0% to 100%.
Setting the feedback to 100% will produce an infinite decay time (self oscillation), while 0% decay will only allow early reflections with no tail.
To clear the reverb’s buffer and stop the tail, click the stop button under the control.
Dry/Wet crossfades between the dry and wet signal. At the far right (wet), input signal is fully affected by the reverb; at far left (dry), the input signal is unaffected.
When set at values up to 50%, the dry signal will maintain maximum gain while the wet signal is mixed in. At values above 50%, the wet signal will remain at maximum gain while the dry signal fades out. This allows you to add reverb on an insert track without decreasing its volume.
Adjusts the input volume of the reverb and offers up to a 12 dB boost of input signal. Comet has an internal saturation in the feedback path, and boosting the input signal takes advantage of this feature.
|Word to the Wiz Try experimenting with different input levels to find the right balance of saturation for your sound.
Adjusts the output signal volume of the reverb.
Adjusts the initial delay between the original signal and the first reverberant sound. The center position (0 ms) represents no delay. Moving the slider up changes pre-delay time in milliseconds (up to 2000 milliseconds). Moving the slider down changes the pre-delay time into tempo divisions from 1/32nd notes up to one whole measure.
Sets the rate of which the density of reflections build up in the reverb. This makes the reverb more dense and lush when increased or more airy and sparse when decreased.
|Word to the Wiz Increase the diffuse parameter to make the reverb even more smooth!
Detunes the tail of the reverb increasingly as time passes. An internal modulation mechanism (not unlike a synthesizer detune effect) is calibrated to create especially smooth clusters of pitch. A little bit of detune goes a long way.
Dampens the high frequencies and rolls them off in the feedback path. The more Hi Damp, the darker the reverb will sound over time. High decay values intensify the damping effect.
Dampens the low frequencies and rolls them off in the feedback path.
The more Low damp the brighter the reverb will sound over time. High decay values intensify the damping effect.
Adjusts the reverb’s overall brightness and darkness. Settings above 0 will boost high frequencies and cut low frequencies, and settings below 0 will boost low frequencies and cut high frequencies.
Click the lock icons to lock or unlock parameters when you switch between presets. When the icons are in the “locked” position, the locked parameters remain unaffected by any change in presets.
|Word to the Wiz Preset-Locks can be used to single out a parameter that needs to be automated independently while automating the preset morph selector.
This is a bypass button. When power is on the effect can be heard, and when it is off, the effect is bypassed leaving the source audio intact.
Bottom Controls #
Sets the amount of time it takes for Comet’s parameters to smoothly transition from one position to another.
The Glide knob increases or decreases the transition time between automated parameters, or when morphing between different preset slots. This effect creates one of Comet’s unique features, an evolving reverb sound that is elastic.
Center (or 12 o’clock) is a glide time of 150ms. Moving the dial counter-clockwise changes glide time into tempo divisions (from a 1/16th note to 16 full measures) moving clockwise increases by time (from 150ms up to 30 seconds).
Preset Morphing Slots
Comet has 5 preset slots created to take advantage of its morphing capabilities. These preset slots allow you to smoothly transition or “morph” between up to 5 different room settings, and are fully automatable. Morphing speed is controlled via the glide knob.
To change slots, click the desired button. To copy a slot just drag the slot onto the destination slot.
* see “Key Switches for Morph buttons” for MIDI control options.
|Word to the Wiz The parameters in the preset slots don’t necessarily have to be a stock preset. Any parameter can be user-defined, and will remain unchanged when morphing between slots.
Click the presets button to open the Preset Library. Or click the arrows to navigate between presets for the currently selected preset slot.
Click Undo to reverse the most recent parameter or preset change, and click Redo to restore it.
Opens the settings page.
Preset Browser #
To browse Presets, click the Left/Right arrows located on either side of the Presets Bar. Clicking directly on the Presets Bar will open a pop-up menu which allows you to browse through the folders of factory presets, save an original preset, or load a new preset bank.
*Note: the user’s original presets are saved to the ”myPresets” folder.
Saved presets can be found in the following locations:
|Word to the Wiz In the preset library, the bottom panel controls are still active. This means that you can still switch between preset slots, adjust the glide, and navigate between presets using the preset selector.
Contains the different categories of reverb presets, including the user created section.
myPresets category lets you manage your own presets.
|Word to the Wiz If you import your own bank it will appear as a category on the right side of the Categories Area
By clicking in the blank area next to “Save” you can type in the name of the preset you want to save, then hit Save to store that preset in “myPresets” category
When in “myPresets” category, clicking this will overwrite your currently selected preset with the current settings of Comet Reverb
Clicking this will delete your currently selected preset
|Quick Tip Use Undo and Redo to go back if you accidentally delete or overwrite a preset
Imports or exports presets to and from the plugin. To export your preset list, click export and select the destination where you want to save the file.
To Import, click Import and choose a comet bank file. The bank will appear as a temporary category under “My Presets”.
To keep presets from temporary imported banks, simply save them.
Clicking presets in imported banks will automatically fill in the preset name making it easy to save presets to the “My Presets” category.
Allows the loading of different presets without closing the browser, effectively enabling the ability to audition different presets before returning to the main interface.
Return to the main interface.
You can choose between whether the size and decay knobs move linearly or circularly. When in Circular Mode, the larger the circle you draw around the knob with your mouse, the more precisely you will be able to adjust the knob. In Linear Mode, clicking on the knob and moving the mouse up or down will change the parameter accordingly.
The size of Comet’s interface can be adjusted to 3 settings: 100%, 150%, and 200%. This applies to all instances of Comet, based on the last setting chosen.
MIDI / CV
Switches between MIDI CC and CV Input Mode. In MIDI Mode, it is possible to assign MIDI Control Changes to Comet’s parameters. In CV Mode, it is possible to assign Control Voltage inputs.
MIDI CC Learn
Map a controller to any of Comet’s parameters. To use, simply click the learn button, then send MIDI CC from any connected controller.
While waiting for midi CC, a red REC is displayed.
The parameter turns blue when MIDI CC has been properly received To remove a MIDI CC from a controller, click “Unmap”.
Word to the Wiz: You can also type the CC number to assign MIDI, but you must first ensure that the plugin channel is receiving midi signal
Control voltage signals may be routed via the side-chain inputs of Comet. Click the CV button to select which channel (left or right) will control the parameter, or select “Stereo” to have stereo modulation enabled.
All CV signals are routed through our Glide mechanism except: morph slots, bypass, and tail stop which also do not have a stereo cv option.
We highly recommend using our GateKeeper Plug-in to generate CV signals for use with Comet.
- Pro-Tools does not support stereo side-chain. Right and Stereo options will use the left channel.
- In Logic Pro X one must route through a bus channel for stereo CV channels.
Return to the main interface.
Controlling Controllers: #
Reset to default
To reset a controller to its default value, double-click it.
To fine tune a controller press “Shift” while dragging the controller.
Sliders will also allow for fine tuning when dragging the mouse away from the control (to the side for vertical sliders or up or down for the wet slider which is horizontal). Round movement for knobs also allows finer control when moving away from the knob.
Comet’s controls have a numeric display which shows their current value. To type in a specific value, simply double-click the number and enter a new value.
MIDI Controls: #
Comet’s Size parameter responds to MIDI notes for a key-follow effect. C3 key is the center and has no effect. C4 will shorten the reverb by a factor of 2 (up an octave) and C2 will lengthen it by a factor of 2 (down an octave). For this function to work, “Note Control” must be enabled.
Note: At very small sizes (under 10%) pitch tracking is not 100% accurate due to non linearities.
Pitch bend also controls the Size parameter. The range is set to one octave up or down. For this function to work, “Note Control” must be enabled.
Key Switches for Morph buttons
Notes C-2, D-2, E-2, F-2, G-2 are mapped to change the morph slot selection respectively. For this function to work, “Note Control” must be enabled.
MIDI Program change
You may send program changes on MIDI CC #119. The control value will correspond to the preset order in the “myPresets” folder (the first 128).
MIDI CC #120 is a panic control – it will stop any reverberation by clearing the buffer.
It is also possible to click the stop icon under the Decay control.
If “Note Control” is enabled, pressing note G#-2 will stop the tail.
With or Without MIDI? #
Comet can be inserted into audio or instrument tracks just like any audio effect. However, some of its features involve responding to MIDI notes and MIDI CC messages.
If you would like to use Comet as a regular effect, just load it in one of the insert slots on your DAW, and you’re done!
