If you're using tape to close off the 4 highest and 4 lowest notes on
an 88 notes player so that you can play reproducing rolls on it, the
best thing to use to remove the adhesive residue left behind after you
remove the tape is Naptha on a soft cloth. Use new, fresh tape, as opposed
to some that's been around for a couple of years and don't leave it on
the tracker bar for weeks at a time or you may have to resort to naptha
and 0000 steel wool to remove it.
