About
Chord Rotator is a harmony generator or rotator instrument. It creates harmony from a single note in a rotating mode. Previously, this technology was only available for MIDI instruments. Now, it is available for single-note acoustic instruments!
One voice follows the input pitch at a fixed interval and the other voice "rotates" through the pitch shift settings. This produces three output notes: the original voice, a pitch-shifted voice at a fixed interval and a third voice that changes.
The "follow" pitch shifter follows your input voice at a fixed interval. The three "rotating" pitch shifters will rotate - that is, a new input pitch will advance to the next rotating pitch shifter. Set the mix balance to blend original input and effected signals. Analyzer speed adjusts the sensitivity of the signal processing.

What's New in Chord Rotator
2.6
March 20, 2023
Version 2.6 now adds the ability to specify a note to trigger a specific rotator step. Previously, Chord Rotator would step through each configured rotator with each note played. Now you can trigger an exact rotator when playing the specified note.
