Virtual Drummer is an excellent application for quickly and easily recording a complex drum track. Many great drum sounds are included, and importing additional sounds is easily done. Tracks are built graphically in a point and click interface with good control over tempo, and a nice visual representation of what's happening. Files can be saved as QuickTime or MIDI files.
