Hello Mr. Smeuuh,
If, in fact, you intend to play the piano in a wedding environment, I may assume the space is large enough to accommodate 100-200 people. Such an environment probably contributes its own "reverb tail" to the sound. One might consider disabling Pianoteq's convolution reverb, if the room is already fairly reverberant. On the other hand, if you determine that the room's sound is dry (i.e., has heavy carpeting / draperies, etc.), you might consider selecting one of the more reverberant presets.
Next, one needs to consider whether the acoustic space is bright or dark in tonal response (and whether the Public Address system / Speaker) sounds bright or comparatively dark. Depending on what you find, you might consider brightening up a "dark sounding" space and/or PA system -- by choosing a preset whose hammer hardnesses are towards the high side; or you might consider other presets what address the opposite direction in brightness.
Happy playing at the upcoming wedding, and please be sure to report on your results, once the gig has been played!
Cheers,
Joe
