The installation went pretty smooth. I appreciate having the 2 free packs and an IR selection of VallhallIR as factory content. Minor thing: there are no presets but those often are a first step into understanding a plugin. Just add some (maybe show how some of the free IRs were made or show something uniquely to this plugin).
I immediately was surprised positively how straight forward the interface is. No uneseccary bling bling or glossy 3D models but pure information what's going on. It offers full control over the sound in a "What you see is what you get" approach, means each controls action is directly visible in a display or waveform. And there are many controls to shape the sound. Besides simple low/highpass the tilt is a neat feature; never saw bending but turned out with interesting effects; same for simply delaying in the stereo field.
The loaded IRs got sample rate converted and phase aligned automatically which already makes this plugin worth having installed imo. Latency and length is adjustable on the system page (which btw shows a whole bunch of useful extra information). Mixing up to 4 IRs with the x y pad was an easy task. Usually I only was mixing 2 IRs but having the option to just add some more worked out well and helped getting better results easily.
I'm not sure what this compare section is about. It's a whole subsection but effectively has 2 controls. Okay comparing your mixed IR to something else is one application but why is it then copied to a slot when consolidating? It's not clear to me what purpose this section has or even if it is already finished tbh.
But my biggest issue: I can't scroll inside the browsers. That + the view mode that lists all IRs in a folder and subfolders is not a good combination cause navigation relys soley on 2 buttons. That's a pita.
Some minor things I'd wish for: help texts or tooltips. Needing to read the manual to figure out what some buttons do is not optimal. A small tooltip at least saying the name of the control would already help much. Also an option to change the signal flow could be an idea. Like putting the EQ match as last step or first apply the output options and then compare it to something.
In conclusion I don't think it's a game changer but that doesn't make it less interesting. It definitely has unique features and I like the full control over the sound as well as the WYSIWYG approach. But it needs refinements in workflow and more clearing things up. Furthermore the price and its transparency need a rethink or otherwise pump that plugin full with features to make it really worth it. I feel like I already like it more than some other solutions that's why it still ended up getting 4 out of 5 points. Of course going to edit it if problems occur during further testing.
