I've also had this problem, but I believe that I've solved it with the
additional step of doing an intermediate mix after each track is recorded,
then using that mix as the monitor track for the next record track. Put
simpler, after the piano and first vocal track, mix them to a single track
and use it to record the next vocal. Then mix all three for the next
vocal, and so on. The extra step is time consuming, but I've found it pays
off in the final mixdown.
