Rechoir is a harmonizer delay plugin where all the echoes can either harmonize with the source signal or be pitch shifted manually.

Harmonic changes can be synced to the tempo and time signature of your sequencer, keeping both the echoes as well as their pitch modulations strictly timed to your composition.

All of Rechoirs parameters can be automated or linked to hardware controllers for maximum control and flexibility when used in realtime during a performance.

Rechoir is free and available in both VST2 and VST3 format for macOS and Windows.
