I don't use kong to solely slap it's shaper in some random place inside a rack to make some transients more alive, workflow etc. But I'll test it now to see what it will do
Edit: tested, kong is indeed good, but khz transient shaper goes much further in settings and shapes, thus delivering more tweakability and sound design capabilities.
Edit 2: ok, i did another test, having a 16th snaredrum (kong standard preset) rolling.
Enhancing the transient both kong and khz transient shaper performed great with khz transient shaper having the most features and deeper settings, Dcam an ok second.
When doing the opposite, reducing transients, khz transient shaper is the only one which totally ducks the initial punch/tick of the snaredrum, while both kong and dcam env shaper still let through some minor percussive attack at the start of the sound.
Edt 3: Again back to testing the snare drum with the shortest range possible, kong does introduce some more artifacts than the khz transient shaper.
Still, khz transient shaper remains my go to device of those three, now i'm off testing it against C1L1 and Mace which I also bought for that super tight transient creation.
Edit 4: khz transient shaper outperformes both c1l1 and mace, mace being second and c1l1 being third when it comes to fastest responds to incoming signal and creating transients.
So I might conclude for myself that I think khz transient shaper is the best one available now in Reason.
