Source Audio Ventris

When Source Audio released the Nemesis, they made a big splash. So when it came time for their next release, they needed a high quality follow up. The Ventris is just that. This incredibly deep, yet easy to use reverb pedal is quite special. With a vast array of sonic option, only expanded by the use of the Neuro App, you can get lost in the echos of this pedal's depth. Its dual dsp capability unlocks immense amounts of creativity and previously unheard reverb landscapes. It has so many features and options, all packed into a relatively small package. This pedal can accomplish almost anything in the world of reverb, and can be a major source of sonic inspiration for anyone who uses it.

HornFX Review

Interface:  4.5/5
The more you explore this pedal, the more you are surprised by how much you can do. Although this has the potential to be a very complicated pedal, it manages, just like its brother the Nemesis, to put all of that craziness and the insane amount of controls into a package that is incredibly easy to use and understand. For the inexperienced pedal user, this is a great pedal to take out of the box and use in the most basic way. But, it is also a magnificent pedal for those looking to have all kinds of crazy tweaks and parameters for each sound. The real beauty of this pedal's interface is that it allows you to use at as simply or as complexly as you choose. It can truly be a comfortable pedal for any user.

Versatility: 5/5
This pedal has SO MUCH. First, there is the 20 reverb engines, that are only further expanded by the use of the app. Next you have the many control options: MIDI functionality, an expression input, on-board presets, optional on the fly tweaks for each sound, a hold function, interfacing with the Source Audio Hub,and of course, the dual DSP. The dual DSP brings this pedal's versatility to the next level. You can have two reverb ready to go at one time. You can activate one or the other, but what is really special is the ability to use both AT THE SAME TIME! The Ventris allows you to either have both reverbs working in sequence or parallel to each other. This unprecedented two-in-one ability can expand your sonic pallate exponentiall and put you into two dimensions of reverb at once. This is sure as versatile as any reverb pedal has ever been.

Quality of effect: 4.5/5
The theme of this pedal is options. And high quality ones at that. Not only does this pedal have enough controls to allow you to make each reverb sound exactly how you choose, but it boasts some of the most organic sounding reverbs we have heard yet. The spring reverb engine in this pedal is a major accomplishment in the recreation of a classic analog sound. The Ventris's 20+ reverb engines are all of high quality and can bring true professionalism to your sound.

Live application: 5/5
This is one of the best reverb pedals for live use that we have seen. The Ventris's ease of use, combined with its incredible flexibility make it a perfect addition to any board. Not only will you be able to achieve anything you could possibly want as far as reverb goes, but it takes into account the challenges of the modern musician. This pedal is almost half the size of any other reverb pedal in its class. That small size males it that much more valuable for any musician who needs to be space conscious on their pedal board. This pedal truly checks all the boxes for live use: Extensive sonic capability, extreme ease of use, small size, and a world of sounds that can truly enhanve your live performance.

These first two clips use a basic hall reverb. There is a clip with Bari sax and Alto to highlight the consistency across the tonal spectrum. This is a great example of the Ventris tackling a standard, warm reverb sound that will be incredibly useful in conventional contexts.

This next clip highlights the ever populat Shimmer reverb engine. This is one of many examples of how the shimmer can sound. The upper octave tones produced by the pedal are incredibly manipulable and customizable.

This next clip highlights one of the more unique reverb engines, Echoverb. This is almost a mixture of delay and reverb and can provide some wonderful etherial effects.

The final clip shows the dual dsp in action. In this clip you hear the Modverb and E-Dome engines in action. This example does not do the dual dsp functionality justice as there are endless possibilities and combinations with this feature.

Trumpet 2

An example of a beautifully effective but not overbearing swell. Actually ducks the natural tone extremely well, considering that the pre-delay is all the way down. 

Offspring is a really cool setting on the Ventris the really creates a grungy metallic like resonance with a trumpet.

This example was made to show the functionality of the 'OPTION' button. This button, when held, will sustain the note that you were playing when holding it, almost like a freeze function.

  • Weight: 1 lb./0.45 kg.

  • Maximum Input Level: +6.54 dBV = 8.76 dBu = 2.12 V RMS = 6.0 V p-p

  • Full Scale Output Level: +6.54 dBV = 8.76 dBu = 2.12 V RMS = 6.0 V p-p

  • Input Impedance: 1 MegaOhm (1 MΩ)

  • Output Impedance: 600 Ohm (600 Ω)

  • 110 dB DNR Audio Path

  • 24-bit Audio Conversion

  • 56-bit Digital Data Path

  • Over 20 Reverb Engines — Ventris features 12 onboard reverb engines accessible via the center selector wheel, plus an expanding collection of reverb engines available via the Neuro Desktop Editor and Mobile App.

  • 128 Presets — Save up to eight presets accessible via the onboard controls or save up to 128 presets recallable with MIDI program change (PC) messages.

  • Dual Reverb Processing — The Ventris Dual Reverb features two independent signal processors giving the pedal essential features like preset spillover and dual reverb effects.

  • True Spillover — Two individual signal processors make it possible to change from one preset to another without abruptly cutting off the reverb tail of the original preset (Note: Spillover is unavailable when creating simultaneous dual reverb effects (A+B on the toggle switch)).

  • Simultaneous Reverb Processing — Select the A + B toggle switch position and create dual reverb effects. Run two reverbs simultaneously in parallel, series, or left/right signal paths.

  • Selectable Footswitch — Choose from a variety of OPTION Footswitch assignments. Control options include preset scrolling, A to B or A plus B reverb toggling, reverb hold, runaway reverb, and tap tempo.

  • Hold (a.k.a. “Freeze”) Control — Use the OPTION switch to hold a small portion of the reverb tail in a continuous loop, essentially sustaining a note or chord until the footswitch is released. While the Hold function is engaged it is possible to play over the top of the loop with either a dry signal or the dry/wet signal from the second reverb processor.

  • Runaway Reverb — Similar to the Hold function, the Runaway Reverb uses the OPTION switch to loop a small portion of the reverb trail. But rather than maintaining a steady sustain, the loop is feed back into the reverb processor, creating a building self-oscillation effect.

  • A to B Reverb Toggling — Use the OPTION switch to toggle between any preset’s A and B reverb, or use it to toggle from a single reverb to reverb A + B.

  • Stereo Input and Output Jacks — Create dramatic stereo reverb effects or set up an external effects loop.

  • Analog Dry Through — For most of the reverb engines and signal routing options the dry signal remains an analog signal and does not pass through the signal processor at any stage while the pedal in engaged.

  • Deep Editing Functionality — Adjust additional parameters, save and share personal presets, and download bonus reverb engines with the Neuro Desktop Editor or Mobile App. (Check the Neuro tab for more details).

  • Complete MIDI Functionally — Receives MIDI program change (PC) or continuous controller (CC) via the 5-pin MIDI DIN Input (also includes a MIDI Thru jack), the USB port, or in conjunction with the Neuro Hub.

  • Universal Bypass — Select either buffered or true bypass.

  • Trails Mode — Rather than abruptly cutting off the reverb trails upon bypassing the effect, Trails Mode allows the Ventris Reverb’s trails to decay naturally.

  • Expression Control — Program simultaneous expression control to multiple knobs with independent depth and direction assignments for each. Compatible with all Source Audio expression pedals, the Hot Hand 3 Universal Wireless Effects Controller, and 3rd party 1/4” TRS (tip hot) expression pedals.
