This script takes a single MIDI note, and generates a chord or a string pad from it, depending on what type of synth(s) you use.

I am violin /cello player – but it would work for any instrument.

It’s run/tested in AUM. I use a gate plugin, and then the A2M plugin to convert the single note input to MIDI.

From the note – I generate and send 4 MIDI notes. The original, the 3rd (or 3rd minor) the 5th, the 7th and the major 7th. So….I’m creating a Major 7th chord.

The script also uses LFOs to continuous change the volume on the MIDI channels the 3rd and 5th note were sent out on.
