Volume on MIDI tracks

When you open the project “Cubase 5” on the midi track, the value of the volume does not match what is shown on the channel. To fix this, need to click on the track and re-enter a specific value. What to do to the volume of the midi track was what set the channel? But it happens with software synthesizers are not part of Cubase. For example Halion 3 or Virus PowerCore.
