Sinevibes Intros Hollow Vast Space Reverb

Sinevibes has introduced Hollow, a “vast space reverb” effect, for Mac & Windows.

At its core is a massive delay network, made up of 24 delay lines, 32 filters, and a feedback matrix with as many as 256 connections. With all settings maxed out, this engine is capable of producing tail times that exceed 15 minutes, while still having a very natural exponential decay.

Hollow includes a variable diffusion stage and a unique bi-directional pre-delay: in addition to normal operation, it can also make the reverb tail precede the dry input signal, opening interesting new creative possibilities. Additionally, the plugin has unison modulation via four phase-shifted sine oscillators – for adding deep, chorus-like vibrance and richness.


  • Reverb engine based on a feedback delay network with a 16×16 matrix
  • Unique two-way pre-delay stage
  • Variable diffusion stage
  • Stereo width adjustable from mono to full expansive stereo
  • Unison-style modulation via four mutually phase-shifted oscillators
  • Variable low-pass or high-pass damping filters
  • Lag filters on all continuous parameters for smooth, click-free adjustment
  • Supports mono › mono, mono › stereo, and stereo › stereo channel configuration

  1. Sinevibes never ceases to impress. It’s unfortunate that this is not available for the Korg family (yet?) but I’m guessing the processing requirements may be beyond what an NTS-1’s engine can handle.

    I still can’t believe the flood of absolutely amazing – and fairly inexpensive – reverbs currently on the market. As recently as a decade ago, something like Albedo (Sinevibes’ Korg-compatible granular cloud reverb) would have cost an arm and a leg, but today you can pick one up and run it on a cruddy little box for the price of a cheapo guitar pedal… Beautiful products.

  2. OK – impressive. But what is puzzling is why they would choose the M-Tron MkII for a piano sound. That’s almost like choosing a Speak n’ Spell for vocals.

    1. it’s sinevibes, the main target audience is for electronic musicians, the m-tron 2 is very musical “electronic” instrument and about 4 days old so it’s perfect for adverting.

  3. I’ve tried a lot of reverbs and this is in the top 5, easily. Its like the reverb section of Roland’s RSP-550 or Yamaha’s legendary White Room. The RSP is how I really came to grasp reverb and multi-effects. I’d still be using it, but Gorgo ate it.

    This is a superior no-brainer for ambient artists, above all else. It can clearly do a lot more, but that looong tail has “Gorgeous Cloud of Sound” written all over it. Use with care!
