When California-based effects company Noise Engineering released their Desmodus Versio in 2020, it represented the first reverb effect in their product line, but they coined a new term for the DSP-based effect: a synthetic-tail generator. The name reflects the reality that it is, by definition, the Desmodus Versio doesn’t create literal reverberation, as in reflections in a room, but instead builds “tails” onto an audio signal. Taxonomy aside, it was a powerful, well-received, and positively jam-packed digital unit.
The Batverb, launched earlier this year, is an evolution of Noise’s tail-generating efforts. However, it uses brand-new code programmed for Electrosmith’s Daisy Seed DSP platform. A stereo effect box that spans delightful and demented flavors of delay and reverb, the Batverb is generously featured and full of unique takes on space-making effects.
Heads or Tails
The Batverb’s main panel includes six knobs, three 3-way switches, two footswitches, and one “bat” button, which you press and hold to access alternate parameters assigned to the knobs. On the crown are input jacks for either mono or stereo performance as well as MIDI in/out and expression pedal jacks. Up to 16 different presets can be saved and recalled via MIDI.
In normal operation, the knobs govern, from bottom left to bottom right, input volume, time, a suboctave chorus, an octave-up shimmer, “regen” or feedback, and a blend of dry and wet signals. When holding the bat button, those same knobs, in order, control output volume, MIDI channel selection, high-pass filter, low-pass filter, duck amount, and expression pedal parameter assignment. The focus switch changes the diffusion of the delay lines. In the left position it behaves more like a delay, while the other two settings sound and feel more like reverbs. Grit adds, in the middle and right positions, a discrete soft-clipping distortion, and duck determines the responsiveness of the feedback. In the switch’s center position, there’s no ducking. At left, feedback monetarily increases when input volume is received, then tapers off as the signal does. At right, the opposite happens, and feedback increases as the signal gets quieter.
Enter the Bat Cave
To my ears, the Batverb’s more reverb-y patches are in hall or room territory—albeit very cavernous halls or rooms. But reverb sounds created by the Batverb’s algorithms sound more authentic to me than many sought-after reverbs I’ve played. Rather than an indistinct wash of sound, the tails here give the convincing impression of your amp’s signal ricocheting around a high-ceilinged cathedral, at first coming back in clearer, sharper bursts, then melting into smeary ambience. And the handy hold feature can be engaged for infinite regeneration by tapping the footswitch, or for a specific window by pressing and holding. That double utility goes a long way toward determining whether the Batverb sounds organic or unhinged.
The sub- and up-octave content injected by the doom and shimmer knobs is more chaotic and spacious than garden-variety iterations of those effects you’ll find on many octave-based reverbs, and that’s a good thing. Like most effects generated by the Batverb it feels like the product of thoughtful, well-considered programming.
The delay algorithm, engaged with the focus toggle at left, is pleasant and plenty usable, and it’s nice to have alongside the less predictable reverb settings. But the Batverb’s deep tweakability means you can still dial in a broad range of both standard and more marginal delay sounds. The chunky transistor-ish dirt summoned by the grit switch widens the palette further. Add in the touch-sensitive ducking (and its customizable parameters), and you’ve got a ton of ground to play with.
The Verdict
Noise Engineering created an outstanding reverb and tail generator here. Considering its steep asking price, the Batverb will be out of the question for many players, but it’s obviously geared to adventurous players and discerning producers, especially those looking for authentic, parallel universe-conjuring ambience and noise in their studio or live rigs. For these musicians, the Batverb will be more than worth the bite it takes from the bank balance.
