Jack...mtr=multitrak
just an idea. sorry if dont help.
what i used to do is lay out the song masters in a piece
of multitrack software...ie along a time line i would
use a different trak in the mtr for each song.
eg song 1 starts at 10 secs
song 2 at 3mins15secs..then a break for you to talk etc..
then song 3 at 4mins after your intro...
sorta idea,
i used to do it in reaper , but any mtr software would work.
