It features two reverse granular delays that can be manipulated by length and pitch. Crystals excels at adding life to boring synths, guitar, and vocals making them sound huge and majestic. From sound design to other-worldly solos, Crystals will spark inspiration. The innovative RIBBON control allows you to modulate many parameters at once.
