I'm happy to share with you my last two M4L devices. I've called them 'DeltaSleep’, as they import real human EEG data recorded during sleep into Ableton Live's environment, which are used to make music. These two devices are part of my attempt to exploit the peculiarities of organic non-music signals to inform music routines and phenomena.
This package is constituted of two devices:
- the 'Modulator' is an effect that lets you map the ongoing EEG signal to parameters in Live, similar to Live's stock LFO, but with a different source;
- the 'Generator' is a MIDI instrument that incorporates the same parameter mapping behavior of the 'Modulator' and integrates the possibility to generate specified MIDI notes according to the current state of the EEG signal and a movable threshold.
As an interesting feature of the two devices, it is possible to loop over a portion of the EEG signal by pressing a tap button (L). While looping, surprising organic melodies and patterns emerge when hitting the 'Quantize' (Q) button, which aligns the MIDI note output to the current Live tempo.
Two M4L devices: one EEG-based MIDI note generator, and one EEG-based LFO
