I'm looking for a DirectX plugin to do multiband dynamics (in
CEP/Audition 1.5); I'll describe what I *don't* like about the two I've
tried and hopefully someone can suggest one that would suit me better:

db Audioware "dB-M": I downloaded the (fully-functioning) demo. It's
intuitive, but maybe a bit too simple. It only appears to do hard
limiting.

Sonic Foundry: This came bundled with my copy of CD Architect. The
filter controls are odd and it's not fully compatible with
Autition/CEP: Only 2 of the 4 bands actually do anything. (All 4 work
when it's plugged in to CD Arch.)
