Larger than the Hall or Room, BlackHole reverb is an Eventide H8000 classic capable of cathedral-type spaces to out-of-this-world soundscapes. This H9 edition of BlackHole has two decay modes (forward and inverse) and feedback around the entire reverb structure that extends the Blackhole sound from huge to infinite.

The standard [SIZE] and [GRVITY] sounds are epic, but try [PREDLY] and [FEEDBK] to take the algorithm to the next level. Try not to get sucked in.

Blackhole Algorithm Controls
Mix [MIX]
wet/dry mixer, 100% is all wet signal
'Gravity' Mode Select [INVGRV]
inverse decay mode of a really big reverb. [GRVITY]: regular decay mode of a really big reverb
Size [SIZE]
size of the reverb
Delay [PREDLY]
pre-delay time in milliseconds or note-based in tempo mode
Low Band Shelving Level [LO-LVL]
post reverb shelving boost/cut of low frequencies with cut-off at 350 Hz
High Band Shelving Level [HI-LVL]
post reverb shelving boost/cut of high frequencies with cutoff at 2000 Hz
Modulation Depth [M-DPTH]
the modulation depth
Modulation Rate [M-RATE]
the modulation rate
Feedback [FEEDBK]
feedback around the entire reverb structure for even larger sounds
Resonance [RESNCE]
resonance of the two shelving filters. Affects sound unless [LO-LVL] and [HI-LVL] are both set to 0
Output Level
At 0 the output level is unaffected. Increase the output level of the effect by up to 20 dB or lower by 30 dB.
Tempo is turned ON/OFF on the H9 by simultaneously pressing the Right Footswitch and the PRESETS button. With Tempo OFF, tapping can be used to adjust delay parameter values (displayed as milliseconds or Hz). With Tempo ON, tempo is in BPM.
Turn effect on or off..
The Middle Footswitch can be programmed to act on the loaded Preset as a programmable controller allowing the user to switch between the normal Preset parameter values and a programmed, alternate set of parameter values. It’s like having two Presets in one.
If Tempo is ON, the display indicates the current tempo in BPM (30 to 500 BPM) while tapping and the Tap LED will blink at the BPM rate. If Tempo is OFF, the display indicates the parameter value (milliseconds for most algorithms).
