I was directed to this developer by PinkNoise. I'm really glad I did.
This is a free emu of the Altec 436c/EMI RS124. I've only used it on a couple things so far, but I'm enjoying it. It's unique.
I needed another vari-mu like a hole in the head, but this does do an interesting thing.
I'm not certain what knobs do what, but I'm guessing Atten is GR, Volume is Makeup Gain. Release is self-explanatory.
I'm most confused by the Threshold set screw. It's not like the threshold on a DBX 160VU. It's super sensitive, I'll say that. Turn it slightly to the right and the needle slams.
