Opti Comp is a smooth, program-dependent compressor that makes vocals and bass sit right with almost no effort. It rides dynamics in a musical way, keeping things even, present, and "finished" without feeling pinched or obvious.

A built-in HF bias makes the detector more reactive to higher frequencies, so fast transients and presence detail can drive the gain control in a natural, mix-ready way, great for keeping sources articulate while still nicely leveled.

And when you want a little extra vibe, push the output for sweet, mix-friendly saturation that adds body and polish.

Opti Comp is free, and it's part of the growing 420 Plugin Suite, built to help you mix more and spend less.

I checked out your website after seeing the free plugin. I haven't tried as of yet, but I did listen to demos of your other plugins. They sound pretty good from what I can tell. Personally... I think it's a bad move to only offer subs for your products. I'm wary of new developers that often end up closing shop unexpectedly. If you're a one person show... I wonder what fail safes you have in place for customers should something unforeseen happens with you. Customers end up with nothing, because the products are on timers and no way to permanently activate any plugins.

i've the same issue.. renting plugins respective licences is something... yeah. at least it is 4.20 for all of the products, not for any plugin separately like i assumed at first.

but still, of course i understand anyone has to start somewhere, thats why we have 6k delays EQ and comps in 10k freebies.. there is so much avaiable even for free, what makes them worth to pay monthly for them ? most stuff most likely is already avaiable as stock (i'm more a fan of 3rd party stuff anyway. too many cringe people with fabulous ideas).
