Inspired by the Neo-Soul sound of the FoundChord preset on BASSalicious 2, this script adds an octave below and a close-voiced Maj 13 (omit 11) chord an octave above the incoming note. Works best on a monophonic input routed to a breathy pad sound.

A mute control allows the effect to be switched in and out. All non-note MIDI commands are passed through without modification.

Accompanying video contrasts original and emulated versions of the preset.

Based on Bram Bos 1-Key Chord tutorial example.
