Doing a song now .. I just realize that I never found a good substitute for the ER in Sonitus reverb ... (and believe me, I tried!, 'cause it's on every single damn music I make for so many years!)
Same for the sonitus delay, the diffusion parameters, and filtering options makes it very useful.
Also, the sonitus compressor is still the one I use: I don't know why, but the DBX preset just "hardens" the sound is pleasing way. I also use it for sidechaining.
The gate is also great.
I can't stand the modulator though .. it just never feels right.
Cheers !
