Henrik Schwarz: The Schwarzonator – a Max for Ableton Live patch ( Free Download )
“The Schwarzonator is a note twister. It’s all about helping musicians (or non-musicians) find the right notes and chords in real time. It turns one finger playing into chords that fit together well. Choose from a list of Chord Sets in a drop down menu. Then all notes you play on your keyboard will fit into the selected Chord Set.”
Requirements: The Schwarzonator requires Ableton Live (version 8.1 or higher) and Max for Live. DOWNLOAD HERE.
