Microstudio should be defaulting the audio level to whatever you have the system volume set to prior to opening it. It will reset the volume back to that level when it closes. If you also have Hoster open, there may be a conflict between who is controlling the master volume.
I tried it and my volume actually went up because the setting I have is up higher.
The key then would be to have your master volume up and then when you open Microstudio, set its main and music level to match that level. When you close Microstudio it should save its internal settings so next time you open it they should be the same as before.
