EZdrummer 

Drums are an essential part of any kind of music. This program lets you create drum rhythm and solo parts for your musical arrangements.

The program has many preset drum arrangements that you can edit according to your needs. It has an interface in the form of a drum set so you can "feel" as if you were playing the actual instrument.

The application has several preset song structures that you can use to create your arrangements. These are very useful to use them as templates. It is possible to edit them and/or design a new arrangement from scratch to save it as a new song structure. You can even mix your arrangements according to the type of song you are arranging.

In general, it is a good and comprehensive program. If you are a music composer, arranger or drum player, it can be very useful for you.

You can use the demo version during 10 days, after which you will need a license to keep using it. To download the demo, you will need to create an account using a valid e-mail address. Also, the file is rather big and comes in the .zip format, meaning that you will need to wait a while until it is downloaded, and unzip it before installing, which will take at least five minutes more. I found both features rather annoying. If you add the fact that the cost is not very affordable, then you may want to check the program fully before deciding if you want to purchase it or not.
