selects the final pitch of the sample, with C3 playing the sample at its original pitch. Drum Rack - a sampler for drums. MIDI notes trigger individual "Simplers" so rather than triggering one sample at multiple pitches, individual samples are triggered at predefined pitches, as is suitable for MIDI drum programming. As is usual with Ableton almost anything can be drag dropped to or from the drum racks; for example, one can drop an audio clip or any MIDI device onto a drum rack note. Instrument Rack - allows the user to combine multiple instruments and effects into a single device, allowing for split and layered sounds with customized macro controls. Analog - simulates an analog synthesizer. Bass - a monophonic virtual analog bass synthesizer. Collision - a mallet percussion physical modelling synthesizer. Drum Synths - 8 devices for creating drum and percussion sounds via synthesis. Electric - an electric piano instrument. Operator - an FM synthesizer. Poli - a virtual analog synthesizer that combines subtractive and FM synthesis Sampler - an enhanced sampler. Tension - a string physical modelling synthesizer. Wavetable - a wavetable synthesizer featuring two oscillators and re-mappable modulation sources. Ableton also offers a selection of Add-on Sample Packs with which a user can expand the sound libraries for their instruments. Session Drums - a collection of sampled drum kits. Latin Percussion - a collection of sampled latin percussion hits and loops. Essential Instruments Collection - a large collection of acoustic and electric instrument samples. Orchestral Instrument Collection - a collection of four different orchestral libraries, which can be purchased individually or as a bundle: Orchestral Strings, Orchestral Brass, Orchestral Woodwinds and Orchestral Percussion. The Orchestral Instrument Collection is included upon purchase of Live Suite but must be downloaded separately. Dedicated hardware instruments Akai Professional makes the APC40 mk II, a MIDI controller designed to work solely with Ableton Live. A smaller version, the APC20, was released in 2010. Though there are many MIDI controllers compatible with Live, these Akai units try to closely map the actual Ableton Live layout onto physical space. Novation Digital Music Systems has created the "Launchpad" which is a pad device that has been designed for use with Live. There are currently four different Launchpad models: Launchpad Mini, Launchpad X, Launchpad Pro, and Launchpad Control. Ableton has also released their own MIDI controller, the Push, which is the first pad-based controller that
