xP for Live



xp-for-live (xp4l) is a fully integrated solution designed to expand with simplicity Ableton Live potential toward the field of spatial sound performance.

The goal of xp4l is to provide Ableton users with a flexible and simplified environment to create true 3d audio projects.

It is made of a free m4l (max-for-live) suit consisting of 5 devices and a standalone application that users have to purchase. We used to call familiarly this package "xP"

xP should not be understood as a suite of different m4l devices, but as a set of tools that work together.

Given the challenge of developing such features in Ableton Live, it was nonetheless important to remain as much as possible in the spirit of what makes its workflow unique, a subtil balance in the direction of artistic creativity and live spontaneity.

The project is partly based on Ircam Spat~ , a library of Max/MSP objects for real-time spatial processing of sounds. It's a unique set of tools for its ability to simulate virtual acoustic spaces.

xp4l is therefore intended for past, new or future users of the Spat library. Although possible before xp4l existed, accessing the library from Ableton Live in the max-for-live environment through a flexible format by users was made complex, and this fact deprived the majority of creators from taking advantage of this incredible tool.

xp4l comes with a solution for every users, regardless of their level of knowledge of maxmsp, that will alleviate this problem, and offers exciting perspectives for further version developments.
