Advanced Features
Introduced in version 1.1.0, we’ve added more than 20 new parameters to help customize your reverbs more than ever. Accessed through the "Advanced" menu, users can now control things like Input/Output Gain, Follow, and Ducking that helps with the intensity and clarity of the signal. There are also momentary switches added to the advanced feature set with Kill and Freeze – the former causing the reverb tail to fade out while the latter holds onto the tail and “freezes” it in place.
We’ve also introduced more advanced filtering and spatial controls with both a Wet Filter and Width knob. The Wet Filter gives users in-plugin control over high pass and low pass settings, eliminating the need for a post-reverb EQ, while the Width knob helps you dial in the overall width of the processed signal (and enables you to push the boundaries of your stereo field with width settings up to 200%).
Rounding out the first half of the new advanced features are the Invert Polarity switch and the Mono Low End switch. These two controls are designed to help clean up any muddiness in your mix – something especially important when working with reverb.
Within the Advanced Features menu, you’ll be able to control it all – Compression, Distortion, Sample Rate Reduction, and Pitch Shifting. Each of these settings are fully automatable, expanding on what the Modulation knob already offers. There’s a whole world of new sounds just waiting to be discovered.
Beyond each effect’s controls, there are also three additional global parameters we’ve introduced to address the decay and modulation rate of the plugin. With the Massive switch, users can expand the decay range of the plugin, making even larger soundscapes in the process. And if the rate of the modulation isn’t quite your style, we’ve added a Sync switch to lock the tempo of pre-delay and modulation to the host, plus a Mod Rate knob for when you’d rather do it yourself.
