Device Details


Name | Version: Spectral Attractors 1.0.1
Author: ndivuyo
Device Type: Instrument
Description: FREE Device!! Spectral Attractors uses a physics simulation and a phase vocoder.


The phase vocoder sounds whatever spectral content is in the current “state”. The “state” is attracted to up to 4 other spectral “states” called “attractors”, which attract the state via the physics simulation with two different modes:

(1) FFT Mode: physics simulation is in 12288 dimensions (a bit higher CPU as a result) in which every FFT frequency bin amplitude, phase value and previous frame value for both left and right channels is a dimension, which results in a complex soundscape and combination of spectrums.

(2) 2D Mode: physics simulation is in 2 dimensions, in which attractors are spread out on a 2D plane based on their spectral differences. The sounding “state” then depends on how close it is to the attractors in a 2D space, resulting in spectra closer to the original attractor states. This mode also includes an option for either interpolating or crossfading based on distance to attractors.

Attractor states are selected by taking “snapshots” of audio in a buffer, which can either be a dropped sample or recorded live from routing audio from another track in Live. Additionally there are parameters for controlling the physics dynamics and real time frequency domain pitch shifting.

- Fixed issue when loading first time in live, right channel would have a buzzy saw-like sound.
- Added feature to randomize attractor states from a randomly selected position in the sample

It’s best to use the newest version of Live, however, it may work on older versions but hasn’t really been tested (especially the presets may not load correctly on older versions)

Has not been substantially tested, so lemme know if there is anything wrong and check here again for updates in case!

CPU will change a lot depending on physics speed, # of attractors and if in FFT or 2D mode.

everybody help! Dillon's been swallowed by the the FFT monster again!

Another fantastic build, it would seem.

I get the error "jsui: error calling function paint [attrDips.js]" - a freeze error?
Hmmmm lemme check thanks for the catch andreas!! Good to hear from ya
Hey it seemed to be frozen fine, and none of the testers reported that. I just refroze it and reuploaded it. Does the error persist? Thanks!
great work - thanks!
hey! :) That's great, it seems it's a "loading MfL devices in Max" problem, it runs just fine in Live. Weird, I've never seen that before, I think.
really cool especially once you understand it
Hey Dillon,

Awesome work, once again.
The device is flooding Live's undo history though.
@Crampe, I do not get any flooding of undo history. Are you referring to when you create a new state? Or maybe you have an LFO mapped? But if so please reach out to me at so I can look into it
absolutely nuts, tysm
I sent you an email Dillon.
