I'm not positive about the specific model... But most multitrackers have one fader that can control more than one track... Not sure about the Tascam though... For instance... Boss makes a line of digital multi trackers... On their 8 track recorder it has 8 faders.... corresponding to the 8 tracks... However, the last fader can be used to control multiple tracks... all of which will be operated at the same volume level... So you could have up to 16 tracks... 8 independantly controlled... then 8 more controlled off of the 8th fader.... I'm not sure if there is a feature like that on your Tascam... I'm assuming that your Tascam is the one that records onto cassette tapes... So I'm also assuming that you're left with just the basic 4 tracks... Those aren't meant to be hardcore recording devices... but rather just rough tools to lay out songs and to get ideas down.
