Max for Live embeds Cycling ’74’s Max environment in Ableton Live: patches become devices that sit in the chain, see audio and MIDI, expose parameters to automation, and save with the set. It ships inside Live Suite and as an add-on for Standard.
The platform turned Live into an ecosystem: LFO utilities, granular instruments, hardware bridges, and visual systems all distribute as .amxd files. For visuals specifically, M4L is what lets analysis live inside the project rather than beside it.
Photism is built on it, with Jitter-free rendering handed to the browser GPU. The roundup of visual devices lives in our Ableton visualizer guide.
