Drummer Boy is a great cheap alternative to a full blown drum machine. With 20 great preset drum kits the majority of which with starter loops.
You can create your own drum patterns with kits ranging from acoustic to electro and with several instances of Presence XT playing the Drummer Boy library its possible to create some complex drum patterns inside Studio One.
This library has kits that are panned and leveled on one side of the keyboard, and unpanned and unleveled on the other side so you can create your own style and add your own fx.
The library also contains one shot kits to create your own patterns along with loops and fills as a starter or to add to or just simply for inspiration. Check out the audition samples of this library.
