I was constantly listening to modules (first with DMP and later with Cubic Player) and DOS shelling from the player to do something else. That something else being editing ascii/ansi art or programming in Turbo Pascal.

When the music ended I had to quit the application I was working in and "exit" from DOS shell to give control back to player software. And then back to DOS shell and into the application.
