Description

This one goes out to all the non-perfect pitch musicians out there.

Achord is a Max for Live application which is able to detect tonal information live, directly from an incoming audio signal. Surprisingly, although the supporting research is nearly 20 years old, this sort of application is not currently offered by anyone else within the Max for Live community.

This form of spectral processing is primarily made possible by going beyond the built-in Max objects and instead using the new Node for Max API to do all the hard work.

How-to-use

The patch should be active when you've dropped it in the device area - this is indicated by the red light. Stop and restart are self-explanatory.

There are three chord modes you can choose from:

- "majmin" detects only major and minor chords

- "majmin7" which in addition to major and minor, detects major7 and minor7 chords

- "all" detects major, minor, major7, minor7, dominant, augment, and major minor chords

Please be aware that the app is still in beta so may be prone to crashing, so please let me know if this continues to happen so I can continue to improve stability. Please report any specific issues or submit feature requests via the GitHub link provided. Also check it out or hit me up if you want to learn more about spectral processing using Node for Max.
