When it comes to snare compression, be aware of the different sounds that compressors will create. Even if you just use plugs, their behaviour will vary quite a lot. Some thoughts:
- In general I do prefer VCA-style comps, or one VCA as a peak-comp and another comp in RMS mode afterwards.
- Emulations of the 1176 will do fairly good.
- I found the Waves C1 to be quite metallic (sometimes usefull) on snare.
- For an instant, nice, wood-like "smack" just drop in the
Blockfish and raise "compression".
Best wishes.
EDIT: Oh yeah... controlling the transients, you might use a distortion (like vespiz said) or some saturation (for freeware I would recommend Jeroen Breebaart's
Ferox). Some of us even clip the snare (
GClip). And if you wanna try the LoFi-thing not having ProTools: E-Phonics
LoFi is great.
