Roy-
The function that you refer to is called "Symul-Sync".
This is not the same thing as the camera / sound "sync" so elloquently
described by another poster.
This function applies to all "Multi-Track" recorders. Regardless of tape
format, or number of tracks,  they all work the same way.
In a four channel type unit, such as the porta-studio and it's many clones,
the tape "real estate" is divided into four separate highways, or "tracks".
Each track is written by a head segment. The segments are stacked
vertically, one directly above the other.
The switching circuitry in the electronics allows for assignment of each
head segment to be either a record, or playback head, at the whim of the
operator.
If you record your Autohart on channel one and decide to play your bass over
it the next day, you merely assign challel one to play back, and channel 3
to record.
You are now "simultaniously" in recording and playback mode at the same
time.
The fact that the two tracks in question are physically at the same point in
time, as far as the moving tape is concerned, insures that the two resultant
tracks are "synched"  and sound as if they were originally recorded
together.
Hope this helps.
