Brooks GS 15 Edit

A switch that does different things depending on the operational mode that the machine is in:
1) If a computer-controlled transport is in "Stop," pushing the "Edit" switch deactivates the computer-controlled tension system and allows the reels to be moved by hand to find the exact spot desired on the tape.
2) If the machine is in "Play", the "Edit" switch makes the take-up reel cease taking up the tape and it falls to the floor.
3) If the machine is in a fast-wind mode, the tape lifters are defeated so the tape is in contact with the reproduce head and the engineer can hear where the selections begin and end.
