They are,an a word:
AMAZING.
I've been doing DAW recording for almost 11 years. I've had ALL the ProTools plugins, all the VSTs you can think of, etc...
These are great,because they are:
1. Simple to use.You twirl a knob a little ways,and you can hear the sound changing. Not like other plugins where you find yourself twisting away and wondering if anything is happening.
2. Sound great. they actually start to distort nicely if pushed a little too far. Just like the real compressors, EQs, and limiters. Other plugins no matter how hard you hit them, they just pankace your sound
cleanly. No way to get that "grit" like analog sound, unless you use these babies.
3. They are different sounding than the alarmingly large collection of "different" plugins out there,which all sound too similar, or are imitating other plugins, without telling you.
4. No need for DSP chip cards, and you can get a LOT of plugins going on a dual-core Mac. I mixed a rock record recently on my laptop, and used these set up just like a console: 1 EQ and 1 compressor per channel. WOW!!! The songs averaged 38 tracks each, and being able to eq and compress each channel easily and have CPU left over for reverbs/ delays, was a dream come true. Try that with other "name" brand plugins...yeah...right... Waves usually could give me at most 12 instances of their "renaissance" EQ and compressors. Not nearly enough. I'm not renewing my "Yearly Bloodletting,oops..I meant Subscription" with them.
My favorite are the 5-band PEQ5B and the LM-662 Limiting Amplifier.
Cheers
