This is a software MIDI editor for Mutable Instruments awesome DIY synthesizer, the Shruthi-1.
This stand-alone software was entirely done using MAX 6 software from Cycling74.
It allows edition of all the Shruthi-1 parameters from a single screen through a MIDI connection.
It can send and receive patch data in SYSEX format.
Last but not least, the editor is open-source and the MAX project files can be downloaded from my GitHub.
Download the source from GitHub https://github.com/smugrik/Shruthi-1-Editor
Download the binary for MacOSX http://smugrik.org/downloads/Shruthi-1_Editor.app.zip, unzip and just drag and drop to your Applications folder.
