The Eventide Blackhole plug-in produces reverb effects that emulate huge spaces and cosmic soundscapes. The Blackhole reverberator has evolved over the years to simulate massive reverbs for sound sculpting without limitations. First offered in the DSP4000 and later in the H8000, it has been tuned, expanded, enhanced and released in a Native plug-in.

Blackhole’s soft attack and lingering, harmonic tail cause it to really shine on guitars, strings, and pads, but those same qualities also allow it to transform a drum track into something other-worldly.

Levels and Monitoring

IN controls the input level to the plug-in, the range is between -60 dBfs and
+12 dBfs. This parameter sets the input level for both the wet and dry

OUT controls the output level of the plug-in, the range is also between -60
dBfs and +12 dBfs. This parameter sets the signal level after the mix

METERS indicate the audio level before and after the reverb algorithm.
These meters are after the input level control and after the output level
control, respectively, to aid in level adjustment.

OVERLOAD indicates an overload somewhere in the reverb’s signal chain
and indicates that you may want to reduce the input audio. This is a sticky
indicator, so once it fires it will stay lit until cleared. To clear the overload indicator, simply click on it.

Blackhole Parameters

MIX – determines the relative level of the wet and dry signals
in the plug-in. It has a special nonlinear taper which puts most of the knob travel in the most usable range.

GRAVITY – is the Blackhole’s equivalent of decay time. On the right-hand side, the GRAVITY control sweeps through its forward reverb range from a very
dense decay to a very long and smooth decay. On the left hand side, the
GRAVITY control is in its inverse mode and sweeps through a range of  reverse reverb-like settings.

SIZE – determines the size of the reverb. This can range from cartoonishly
small to cosmically epic.

PREDELAY – sets the amount of delay before the reverb section. When
tempo mode is off, this ranges from 0 to 2000 mS. When tempo mode is set
to either Sync or Manual, it is set in beat divisions of the tempo.

LOW – controls the level of low frequencies in the reverb tail using a shelving filter with a corner frequency of 350 Hz.

HIGH – controls the level of high frequencies in the reverb tail using a
shelving filter with a corner frequency of 2000 Hz.

TEMPO – This button controls the tempo mode and has 3 states. In TEMPO
OFF mode the PREDELAY is displayed in milliseconds and the plug-in is
not controlled by the tempo at all. In TEMPO SYNC mode the tempo is
retrieved from your DAW session and the PREDELAY is set in beat values
relative to the session tempo. In TEMPO MAN mode the tempo is set
manually by either clicking and dragging the tempo value, or by double
clicking and entering a new value with your keyboard.

MODDEPTH – sets the modulation depth in the reverb tail. This can be a
subtle control, which nevertheless can reduce ringing in the reverb tail and
add some motion to the sound.

MODRATE – sets the relative speed of the modulation in the reverb tail. Subtle but useful.

RESONANCE – controls the resonance of the LOW and HIGH filters. When
the filters are set to 0, this does nothing, but when they are active, it can
create a much more filtered sound. But be careful, extreme settings will
increase the chances of overloads.

Performance Controls

KILL – kills the input to the reverb section allowing you to hear the reverb tail fade out. This can be useful to help dial in the sound, or it can be
automated for a more tremolo-like effect.

FREEZE – sets the reverb time to infinite and mutes the input, effectively
freezing the audio in the reverb buffer. Making changes to some controls
when FREEZE is active can allow for interesting sound design.

RIBBON – The ribbon control allows the dynamic modification of several
knobs at once, emulating what you would be able to do with real hardware
in front of you. See the “Using the Ribbon Controller” section for more

HOTSWITCH – allows you to instantaneously toggle between two settings
for any combination of knobs. See the “Using the Hotswitch” section for

more details.
