I thought to post this explanation of the workflow for those of you interested in knowing more about the technical aspect of this project.
First of all, when it comes to create new sounds I love combining manipulation of acoustic sources with sound processing techniques. Sometimes, the idea for a custom built instrument doesn't stop within its physical form, but it extends to the creation of a unique recording and processing technique that completes its sound, and somehow determines how I will play that instrument.
In the Live session, I used the 12 Return tracks as they would be 12 independent sound processors.
Each one becomes a processing line that shapes the initial sound differently, it can be anything from a simple reverb to complex combination of plugins performing radical sound changes.
Once everything is setup, moving the Return faders up or down is like exposing or hiding a particular aspect of the sound processing, and since all the plugins are always running and can feed into each other, the sound keeps changing beyond the initial settings. Also, the single plugins inside the chains can be activated independently and their parameters controlled with any MIDI device.
