I need a Loop Record cut. How and who can do this out there. Is this process easily done with a computer on the lathe? Can it be done without? Anyone out there experienced in cutting these types of records? A loop record is where one side has a number of tracks that loop after about 2-3 min. so each track has a locked groove at the end hence the term "loop Record." I know there is a calculation in the tempo that each track has to be which is (i cant remember what tempo that is right now) HELP!!!!
