Put simply: a multi-band processor. In detail, this means that frequency bands are split up here and can be tackled separately. That doesn't sound exciting at first, but the Source Audio Ultrawave has 37 splitting options. You can arrange the bands in different ways and separate pairs of 2 to 10. The result is a huge number of potential sounds with their own character. The signal chain with a classic touch allows compressors and expanders to be packed before or after the distorted signal and modulated afterwards. Here you have the option of using an LFO to control what works and, in addition to flanger and phaser-like sounds, you can also create tremolo sounds, for example. The frequency bands are correspondingly flexible. In addition, you can use the morphing function to create completely wacky sounds. Two parameter constellations can be superimposed here and controlled via LFO or envelope. Typical Source Audio –thinking outside the box. 

A few words about the connections - stereo outputs make sense, but two instrument inputs don't make the whole thing unexciting - being able to manipulate guitar and synth at the same time from the same LFO. I don't think that's available in pedal format. But the routing options don't stop there, the individual source audio devices can be merged together. If you use one input to send commands from the Neuro app, you can let them travel through the entire Source Audio signal chain. As already mentioned: EXP connection, MIDI and USB are included here. Well - if you know the C4 or the Nemesis, you know about the Neuro Editor. In my opinion, the coolest and clearest editor of this kind ever.
Incidentally, calibrating Source Audio with an app or editor is surprisingly easy and a lot of fun. One of the few in-house editors that justifies having a laptop next to the pedalboard. This is perhaps also the biggest problem of the Source Audio brand: despite all efforts to keep it simple, the applications are heavily dependent on the neuro app or the editor. And many musicians still like to avoid both.

Manual

Ultrawave Multiband Processor

Dieses überragend intelligente Pedal verfügt über zwei komplett unabhängige Reverb Prozessoren, beherbergt also gewissermaßen ein perfektes Pärchen an Hoch-Leistungs-Reverb Pedalen. Dieser leistungsstarke Dual Prozessor ist, was den Ventris von seinen Vorgängern unterscheidet und einen Quantensprung in Soundqualität und Funktion bedeutet. Der Ventris Reverb verfügt über herausragende, weitläufige Sounds, die mit ihren 12 integrierten sowie vielen weiteren online zugänglichen Reverb Engines alles von wunderschönem, natürlichen Widerhall bis hin zu eindringlichen „unnatürlichen“ Klängen abdecken. Der Ventris liefert neben der langen Liste an benötigten Kontrollmöglichkeiten und bietet zusätzlich einige Neuheiten. Der A+B Kippschalter macht es super einfach zwischen den zwei Signalprozessoren hin und her zu schalten oder diese zu kombinieren um einzigartige Dual-Reverb Effekte zu generieren. Stereo Ein- und Ausgänge liefern neben einer ultra-breiten Stereo-Streuung überlebensgroße Ambience Sounds. Der Option Fußschalter bietet eine Vielzahl von hands-free Kontrollmöglichkeiten wie Preset Scrolling, Umschalten zwischen den Prozessoren, Reverb Hold, Runaway Reverb und Tap Tempo. Der Ventris bietet außerdem 8 Onboard Presets und zusätzlich volle MIDI Funktionalität (was die verfügbaren Presets auf 128 erweitert), Expression Control und vieles mehr. Darüber hinaus ist der Ventris selbstverständlich auch kompatibel mit der Source Audio Neuro App sowie dem Desktop Editor und erlaubt somit die Steuerung und Einstellung umfangreicher Effektparameter per Computer oder Smartphone. Die so erstellten Custom Reverb Effekte können dann auf einfachstem Wege auf eine der Kippschalter Positionen bzw. eines der 128 Presets gelegt werden.

This supremely intelligent pedal features two completely independent reverb processors, essentially housing a perfect pair of high-powered reverb pedals in a single box. It is the Ventris Dual Reverb’s powerful dual processing that sets the pedal apart from its predecessors and introduces a forward leap in sound quality and function. The Ventris Reverb’s exceptionally spacious tones, covering all the bases from beautifully natural reverberations to haunting “unnatural” tones include 12 onboard reverb engines as well as an ever-expanding collection of reverb effects available via the Neuro Mobile App or Neuro Desktop Editor. 
The Ventris features a long list of mandatory control functions, and also introduces some bold new ones. The A+B toggle switch makes it super-easy to select between the pedal’s two signal processors or combine them into entirely unique dual reverb effects. Stereo Inputs and Outputs provide a mega-wide stereo spread for larger-than-life ambience. The OPTION Footswitch offers a variety of hands-free control options including preset scrolling, A to B processor toggling, reverb hold, runaway reverb, and tap tempo. The Ventris also features 8 onboard presets, full MIDI functionality (extending the preset number to 128), expression control, external preset switching, and more. Finally the Ventris is compatible with the Neuro Desktop Editor and Mobile App. Connect the Ventris Dual Reverb to either of our Neuro Editors and choose from an expanding palette of additional reverb types. Use the Neuro’s advanced set of deep editing parameters to create highly customized reverb effects. Easily burn your edited tones directly to the any of the Ventris’s effect selector positions or to one of its 128 preset slots.

Ventris Dual Reverb

Von außen betrachtet ist das Vertigo Tremolo aus der One Series ein recht geradliniges Pedal. Mit vier Reglern und drei, per Kippschalter anwählbaren Modi, bietet es bereits einiges an Kontrolle über den Sound des Tremolo Effekts. Und hier hat man bei weitem keine digitale Annäherung an Tremolo. Das Vertigo Tremolo klingt absolut wie ein echtes, tiefes und warmes Amp-Trem.
Verbindet man es via der gratis herunterladbaren Source Audio Neuro App mit dem Smartphone, eröffnet sich noch eine ganz neue Welt an Features wie progressiven Tremolo Patterns, zusätzlichen Modulationseffekten, parametrischen EQ Settings und vielem mehr. All diese Einstellungen können natürlich in den drei Kippschalter Positionen oder 128 MIDI Presets gespeichert und wieder abgerufen werden.

From the outside, the One Series Vertigo Tremolo is a very straight forward effects pedal. Four knobs, three presets accessible via toggle switch already give a lot of control over the sound of this tremolo device. And one doesn’t just get a digital approximation of a tremolo – the Vertigo Tremolo sounds absolutely like a real, deep, warm amp-trem.
Connected to a smart phone via the free Neuro App a new world of features like progressive tremolo patterns, additional modulation effects, parametric EQ settings and a lot more opens up to the user. All the settings of course can be saved to one of the three toggle positions or one of the 128 MIDI presets.
