You should also know that you can link the volume faders and buss faders. One thing I always do at the beginning of all projects is link the master output faders to the L/R interface....
if the faders of the other 3 tracks are following the movements of a specific fader that you are adjusting manually, it is possible that they are somehow linked together. In the track inspector and I don't recall if this is in track view, I'm 99% sure it is in console view.....there is a small....very small color light that lights up to show which tracks are in a certain group. It's near the fader.
Cakewalk calls this GROUPING. All sorts of things can be grouped. Simply right click on the fader or control and the grouping menu/window opens. Used groups are marked with *. Simply click on the existing group to add that fader to it or again to remove it or an unused group to start a new group. All sorts of cool things can be done in grouping. Do this from the console view mode. Most often it is used in orchestral composition to group the faders on the strings all together, and so on....
I only use the grouping on the master output so I can grab either one and drag the volume up or down. In the tracks, I make sure to not use groups. I prefer to use individual envelopes for level control with automation. Automation only works in playback and it overrides all manual fader manipulation. For example, if you move a fader when playback is stopped, as soon as you start playback the level will snap back to the enveloped level.
Cake's MP3 converter. Yeah it is on a 30 day trial. Many of us use a third party converter. Some use Audacity. I prefer Wavepad. both are free on the net and do a fine job.
