So far, after four weeks of using, I really like the NightverB. I've connected it to my audio interface outputs and set it up as return channel in my DAW, thus in full wet mode. It creates both beautiful silky textures as well as 'platey' ones.
Having dedicated knobs for each function is definitely a benefit over a plugin: you don't have to use your mouse and you don't have to remember the mapping on your MIDI controller.
And speaking of mapping (but don't tell Erica Synths): I'm also using the NightverB as a controller for my reverb plugins, which is easy to setup because all knobs send out MIDI CC. Just remember to change to MIDI channel per plugin, or your controlling them all at once.
One star less for 'Afwerking' because the Bass and Trebble are marked -18dB to -18dB.
