VirtualMidiSynth too quiet in some games - how do I boost the output?

Hello and thanks for this great software.

I use CoolSoft VirtualMidiSynth in Windows 8.1 . I have simply replaced the default Windows midi mapper entry in the registry with VirtualMidiSynth. (I found the solution in this forum)

Quote:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32\midimapper

I simply changed the value from "midimap.dll" to "VirtualMIDISynth\VirtualMIDISynth.dll". And ... it works."

This works fine, but I noticed that the output of most games is too quiet for my likening (eduke32, and the Doomsday engine to name a few). I checked the midi mixer from VirtualMidiSynth and the output settings in the game. Both are set to max. I also tried various different soundfonts. Is it possible to boost the output of VirtualMidiSynth even more?

The output of Windows Media Player is fine.
