I downloaded midi drum machine program on the internet a while ago for free, but then my hard drive crashed and I lost it. I wanna re-download it but I don't remember the name of it.

Its a very very simple program. On the y axis of the program, there's the names of percussion instruments that are availabe to sample. On the x axis, there are small boxes which you check to have the instrument play at the times you want.

Sorry if this description isn't very concise. All I remember is I googled it and downloaded it for free.
