What I find dope about how you guys at UAD cracked this plugin is q you didn't take the easy way out using static impulses on some wack convolution engine q dies the second dynamics change. Real talk, desoldering the EPROMs from the original mainframe to dump the v4.4 firmware binary code is the exact level of reverse engineering an engineer expects in the studio. At the end of the day, what I got inserted on the channel is the actual 1978 algorithm processing audio in real time, plus the non-linear behavior of those 12-bit converters with floating gain. That mathematical imperfection and the 20 kHz aliasing is exactly what makes the reverb tail sit itself right in the mix without fighting for space against the transients or forcing me to slap an EQ right after to clean up the mess. Chéveres results, no doubt.
A killer operational fact in this modeling is the emulation of parameter zippering on the control surface. On the original vintage hardware, moving the faders aggressively during a track generated discrete steps in digital gain q translated into a subtle staircase noise; UAD maintained this behavior in the DAW automation, opening up a field for experimental non-linear sound design q is impossible to replicate using standard data interpolation techniques. well done!!
