Hi OTT, I think I remember you saying it was important to "look after the transients" - what do you mean by this - I know what a transient is, but how do you look after them?
You make sure you don't 'snap them off' with inappropriately-set compressors, limiters and saturators.
A limiter or high-ratio compressor with too fast an attack setting can round off the front of a sound in such a way as to make it unrecoverable. Even with transient processors like the SPL or Sony TransMod it isn't always possible to recover a carelessly-dulled transient.
The transient portion of a sound is vital for placing it in a mix and great care should be taken to preserve it in relation to the body of the sound.
