It can be used as a standalone application or as an AUv3 MIDI effect plug-in. The chord is generated by adding up to 8 transposed notes to the original note played. Once the chord is generated, it is quantized to limit it to the selected output scale. The application supports full internal and external MIDI connections for input and output. An internal sound bank is included. The AUv3 MIDI effect plug-in supports multiple instances. A compatible host is required to run the plug-in.
