MetaFlanger

MetaFlanger produces vintage tape-flanging, phaser-emulation, and special effects like no other flanger, ever. Create gentle choruses, sharp phasing effects and a variety of true dual-delay flanging sounds quickly.

The wet signal includes filters so you can flange or phase just part of the signal (and they are FIR filters for absolutely perfect harmonic alignment). Harmonic Convergence in a plug-in.

Also features phase inversions at all key points, extensive factory presets of vintage emulations (Mutron, MXR, Itchycoo Park) and more.
