I use Sony's Vegas for video editing and Sound Forge 9 for audio mastering.  I have been trying to find a small controller that will work natively with these programs.  The Alpha Track seems to have what I am looking for, but do not want to waste my money if it will not handle my programs.  I do use ProTools 8 occasionally and know it is compatible, but do not want to be limited only to ProTools.  I know that Vegas is compatible with Tranzport, so what about A.T.?
