drum machine software

[Brick Top]

I hope this is the right place to pose this question.

Does anyone know of a simple program to simulate a drum machine that I can practice to? I have band in a box....but I can't figure out how to just have it play a simple drum beat in 4/4.

Free would be ideal.

Cheers,
BT

Hammerhead 2.0 fits that criteria exactly.
