Questions regarding Loudness of Pianoteq

Hi,

i use 6.5.1 on a W10 system.

I noticed 2 things regarding the loudness of Pteq:

1. Other Apps run much louder than Pteq. Thus i always need to re-adjust my Volume settings when switching to and from Pteq to other Apps.
2. When loading / playing Midi-files, so far all seem to play at a (much) greater loudness than when i play via the keyboard. Thus again adjusting of Volume is needed.

Which raises the questions:

a) Is there a way to avoid this re-adjustments in general?
b) Can the loudness of Pteq be increased somehow to match the loudness of other apps?
c) Can the loudness of Midi-files played be changed from within Pteq?

Perhaps the Audio Pros here have any idea?

P.S.: The easiest / quickest way to do the adjustments needed for me right now is via the Voicemeter Virtual Audio Mixer (free for End Users), which can be found at https://www.vb-audio.com/Voicemeeter/index.htm. Perhaps some of you guys here will find it a usefull tool too. Still i'd prefer to not have to re-adjust Volume before, during or after using Pteq.
