What is this?

The Harmonync is a platform that allow the user/musician to play the Harmonic Series and changing its fundamental tone in real-time. Just like the overtone singers do with the polyphonic overtone singing technique. The idea is to play a fundamental-variable harmonic series on electronic and electro-acoustical instruments retuned via MIDI and in real-time. The name come from the union of the words “Harmonic” and “Sync”.

Read the “Project Overviewfor more details.

Actually the Harmonync is prototyped as a patch for Pure Data using the Extended Libraries. The first release was developed with Pd-extended 0.43.4 for Mac OS X but it should run on other platforms.


Quick Start

  1. Download Pd-extended here, and install it. If you are using Mac, you need X11 installed.
  2. Download the last version of Harmonync patch from the project page on GitHub, then unzip the files in the archive.
  3. Run the harmonync_gui.pd file.

Note: Do not rename or move any other file inside the main folder. Move all files and folders together.
