Max for Live
Max for Live allows you to harness the power and flexibility of Max inside Ableton Live. Using Max for Live, you can build your own devices and tools that enable you to completely control and shape how you work and create with Live. You can make:
You'll be able to connect custom hardware controllers, design sequencers, process audio in novel and exciting ways, and much more.
Example Devices
Live Suite users have access to a wealth of packs on the packs store. From here you might get an idea of what Max for Live lets you build, including sequencers, custom note transformations, tools for controlling modular synthesisers, bespoke instruments and more.
There are also some parts of Ableton Live's software that are built using Max and it is a fully capable tool for making high-quality, professional devices. For example, Convolution Reverb, Granulator II and Granulator III are all devices made with a combination of Max and sometimes RNBO.
Lastly, one of the major strengths of Max and Max for Live is its community and the spirit of sharing that comes with it. There are lots of great devices that can help you feel inspired by other people, often found at https://maxforlive.com.
Learning Resources
Max for Live extends how you can use Ableton Live through a combination of objects, abstractions and APIs. All of these different tools and capabilities are embedded in "devices". A device is file ending in the .amxd extension which can be loaded and used in Ableton Live, much like the existing library of devices that are shipped with Live. A Max for Live device can contain patchers, abstractions, media and anything that can be added to a Max collective. To begin putting all these building blocks together, we recommend the Max for Live Building Tools pack. This pack guides you through building your own devices, while also offering over 130 devices that you can use as the basis of your own experimentation. You might also want to investigate both the MSP and Max tutorials to get a better handle on the mechanics of patching just in Max.
Another option to supplement this is to take a look at the Max sidebar and the Max for Live clippings and snippets. These include lots of helpful shortcuts for putting together your own work.
