Muse Sound echo

No complaint, rather a question:
I am using a score with woodwinds and while entering or clicking an existing note, the sound is "dry" and short. When playing the score though the instruments disappear into a "far distance" with an extreme reverb / echo like in a cathedral. The sound of single instruments (or human voices in "choir") is very nice and natural, but the overwhelming echo leads to a somewhat blurry sound cloud in a multi instrument score. Is this an effect of the beta version of Muse Sound and is there hope for me, that I can control the amount of reverb / echo in the final version, so I have the excellent sound but without or only very limited effects? I am mainly using the software to create rehearsal sound files, and there it is important to hear the end of a note as good as the start, which is impossible with this amount of echo.
I very much like the look and feel of MS4, very good job there, developers! :)
