That’s the classic tric chorus sound! I love it. In this video he is using a pitch detune of -9 +9 cents (use H9 Micropitch algo for that). Not sure what he is doing with that 310ms delay and how that is routed exactly in combination with the detune. Also some reverb is added. So it is more than one algo.
Thanks! Yes, the tri-chorus! LOVE that sound. Wonder if Eventide has something that sounds like the tri-chorus? Well thanks. I’ll keep searching until i get close. Maybe someone else will chime in with more info.
