QuantiChord

"QuantiChord" is a MIDI effect that generates chords from incoming notes and quantizes the results to a pre-defined scale. It can be used as a standalone application or as an Audio Unit 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 Audio Unit MIDI effect plug-in supports multiple instances. A compatible host is required to run the plug-in. The host must support the Audio Unit MIDI effect format.
