Ableton Suite Instruments
This download contains a collection of Live Packs which install content for all of Live's add-on instruments. These Live Packs can be installed individually or all at once. After downloading and unzipping this collection, open Live and drag the alp files into Live's window.
After installing the Packs, presets can be loaded from the Instruments folder in Live's Device Browser. Depending on the instrument, the presets may be further subdivided by category (as in the example below):

Additionally, the Operator Live Pack installs a collection of Lessons to help you learn more about the instrument. These will appear automatically when opening "All Lessons" from the Help menu.
The Drum Machines presets can be loaded from the Drum Racks folder of Live's Device Browser. You can load either complete kits or individual instruments:

The Drum Machines Live Packs will also install a collection of Live Clips to the folder "Clips/Drums/Electronic" in your Library, arranged in subfolders for each kit. These can be accessed via one of Live's File Browsers:

Loading a Live Clip to an empty MIDI track loads a combination of MIDI notes, an instrument and custom effects that you can use as a starting point for your own creative work. You can also drag Live Clips to tracks that already contain instruments and effects. This will load the MIDI data but will not replace any of the track's devices. All of these Live Clips conform to General MIDI mapping, and can be easily swapped between Drum Machines (or even Session Drums) kits.
