Voxengo´s Pristine Space convolution reverb can work with a latency as low as 64 samples (1.5 ms at 44.1kHz), making it possible to use it during tracking.

In comparison, is the latency of the Kontakt 2:s own convolution reverbs low enough to use it during tracking?

EDIT: Nevermind, you can't run external audio through Kontakt's effects. Too bad.
