Reverb Auxiliary "Bug" (Edited)

This is not really a bug per say but it is an issue that could be documented.

For a full orchestra score, more or less with few more instruments than average an orchestra, the playback has an issue of playing all notes smoothly without stuttering.

Edited: Apparently audio fx isnt needed to use the innate reverb so that made it the playback system sweating to play reverb effects!
