Hey ,
Can you be more specific in which kind of plugins you need ? ( or maybe what are you up to ? )
Tessla SE is a plugin i like a lot ( thats not a compressor )(freeware)
Of course you could take an idea of what kind of vst's you could try ( if you are just experimenting with new stuff ) by just checking a mastering bundle ( like waves ) and finding simillar freeware plugins .
Hope it helps !
Good luck !!
I'm mainly looking for compressor/limiter plug-in's. I have the Waves bundle on my Mac for Logic, but I use that for recording, and I haven't tried it out on my beats. The only third-party vst I tried on the master was the iZotope Ozone 6, but only in a trial version, and I'm not sure that's the right one for me. Any suggestions on alternatives?
