Solid-State-Logic.com finally offers the free LMC1-Plug
for PC too. I bet there will be more plugins from SSL available soon. Here is what SSL says about the free plugin: Every now and again a piece of audio equipment comes along that defines the sound of an era. Back in 1979 Solid State Logic gave birth to a legendary recording console. Capturing the signature sound of the 'Listen Mic Compressor' from SSL's "classic" 1980s SL 4000 Series consoles, the LMC-1 delivers a compression sound perfect for crunching room mics, mangling overdriven guitars or causing sonic mayhem on a vocal track. It was originally intended to prevent overloading on a tracking room 'talkback' mic.
You can download
the LMC-1 after a quick registration.
