I’ve been trying to get my hands on this VST: https://www.kvraudio.com/product/midichordanalyzer-by-insert-piz-here
But the host has been down for several years.
It reads midi input from a controller or a send from within the DAW and reports the chords being played. I haven’t been able to find another free VST like it. If anyone has an alternate download or knows of similar plugins I would greatly appreciate it!
