I've had a look but couldn't find a thread comparing these two directly. Please send me a link if there is already one out there...
I've not used the PC4k Expander/Gate but have used Sonitus Gate plenty. Sonitus looks a lot more flexible. But I'm wondering what sound difference you would expect to hear? I typically use gates mainly to tighten up drum components (often in a parallel chain which I then blend to get the right 'snap' I want). That's about it. Anything else I want gated (eg headphone bleed) I tend to just do manually when I'm comping (might as well as I'm already there). My drums are done with BFD so bleed from other drums isn't an issue for me.
For those of you who have compared, is there much/any difference in sound? Or for what I used it for, would Sonitus be fine? My hunch is I won't get anything extra that I'm not already getting with Sonitus, but I'd love to hear opinions of more experienced users of the two. I don't really use a gate for the 'sound', but more for the technical aspects of what it does. I use other tools if I want a 'sound' or 'color'.
Cheers
