mossman, if your jamming with your band, then why would you need to
record a loop in the first place!
Personally, I think a smaller computer with a large hard drive fed from
a mixingboard during practice is a GREAT way to record a night of
practice and maybe capture that *something* that you would have
otherwise wished you "had the tape rolling".
I even think a computer spinning in the background is easier to work with
the a Reel-to-Reel.
But hey, what do I know...I'm only in the 21st century.
