Thanks, Steve.
I see there's a significant enhancement to MSpectralDynamics, described as "per-frequency attack/release curves". I'm just starting to experiment with that, but what it means is you can now set a slower attack for highs to help preserve transients.
I've been in the habit of routinely raising attack and release times with this plugin, to preserve the "sparkle" of a full mix. The necessary compromise has been that it then becomes less-responsive to lows. Now, I can use the Attack Curve as a "sparkle knob" and hear those acoustic guitar picks and cymbal tings come back, even with aggressive attack and release settings on the lows and mids. This amazing plugin just got even better.
