I've only had this for a week but I'm already grateful I got it. The unit seems well built and it's smaller than I expected, the setup is pain free and it's been really reliable so far.
I already owned a Radial EXTC which I used to process audio from my DAW through my guitar pedals and it's great, but the FreqInOut makes the whole thing a lot easier, without taking inputs or outputs from the sound card, but actually adding 4 line ins and 4 line outs. The plug in is great and the fact that it takes care of the latency compensation is a godsend. Now I can also make any pedal mid/side which is great.
I have it hooked up to my patch bay, so I have every connection at the front so it's super easy for me now to just try out pedals and any other outboard gear I have. It's definitely adding a lot of flexibility to my setup and I wonder how nothing like this existed before!
The possibility of adding and saving picture of the settings with the project is definitely a great touch, I only tried it once so far and it seemed ok. Of course, you can only know the visible settings, any hidden functions are on you to write down and keep track of, if needed, but it's a good feature for sure.
It's been only a week and it'll take a bit more testing of course, but I'm already excited to be using a lot more of my pedals in my productions from now on.
