I am using the free notation software Musink to compose music. My music plays back through a virtual MIDI cable that is connected to a group of virtual instruments, as described in Musink's Help Wiki. I have set each stave's volume in my Virtual Instruments, but every time Musink starts playback, the volume of my virtual instruments resets. This changes how my composed score sounds.
Is this caused by Musink, or by Windows? Can I snoop on the MIDI data somehow?
