This issue has been discussed at numerous times in the past and is not something that can be “fixed.”
The problem is that in most cases it doubles the dsp and memory requirements, albeit temporarily, so cannot be done without hardware changes.
Space does have true spillover, but only as a result of reducing the complexity and delay size of the main effect. It can only be done because reverbs don’t use much delay.
SO, CAN I HAVE THOSE DELAY TRAILS IF I HAVE TWO H9 ?
