Don't do it!

For most parts, I see no point in it.

However, when considering sounds where attack is essentially imminent, 
similar to hitting a bell or some other resonance, it might be important 
to get consistent transient. That's at least when it would make sense.

For slower attacks I would say that if there is an effect, it reduces 
significantly as attacks becomes longer.

The middle path is to allow it to be routeable, but not default.

Now at least you know when I think it may be worth it, if it ever is...

Cheers,
Magnus
