Bill,
You require a normally open momentary contact switch. Your drum machine is started and stopped by the closing of a switch. The switch you have is closed when you step on it and opened when you step on it again. Thats why you have to hit it twice. I have a couple of different brands that I use. One is a Boss FS-5U, the other is a MPM PS-25. Both of these allow you to choose normally open or normally closed. A music store should have what you need, but if you tell them that you want a normally open momentary contact footswith you might just recieve a blank stare. Take your machine with you to make sure whatever they sell you works.
