Its been long time since live 4. Almost 7 years, and this software while keeping ths same core, keeps on inovating constantly. Specially with cycling 74.

Oh and Ableton's own Push controller for Live 9 looks totally sick:

this is really interesting.

9.1 is available at public beta now https://www.ableton.com/en/beta/

Live 9.1 is available

Live 9.1 is now available for all owners of Live 9 Suite, Standard, Intro and Lite editions – head to your account to download it. This update is free for all owners of Live 9, and provides several significant improvements for users of Live 9 and Push.

Live 9.1 introduces support for two windows, including the option to place the windows on different monitors. Want to use the Session View mixer while keeping an eye on the Arrangement? How about using one monitor for tweaking effects parameters and another monitor for editing a MIDI clip? We hope this feature will please those users who told us how keen they are on dual monitor support, and it certainly promises to be a workflow booster for many music-making scenarios.

For Push owners, Live 9.1 introduces a brand new melodic step sequencer. Enter notes manually, or play them in, then edit each note in the sequence precisely ? all via the hands-on interface of Push. Plus, you can now edit automation with step-by-step accuracy – maybe open up a filter for single notes, or add a splash of reverb to the last notes of a sequence. Learn more about this new sequencer in the tutorial videos below:

Finally, there are a couple of under the hood changes that we’d like to draw your attention to. Live 9.1 includes a new rendering algorithm for better quality audio when exporting from higher to lower sample rates – for instance, going from 96kHz to 44.1kHz. Also, rendering now uses multiple cores, which can result in much faster exports. Ultra high-quality rendering and faster renders – now in Live 9.1.
