Igorski has introduced a new audio plugin where the echoes are pitch shifted to create a tempo synchronized harmony from the input signal.
Rechoir features controls for manipulating the delay, adding movement to the pitch shifted signal, decimating the sound (sample resolution reducer), modifying the pitch of the echoes, and it includes a filter to control the brightness of the overall echo effect.
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 available for download for Windows and macOS (VST/VST3). Linux users can build the open source effect from source.
