"As a professional mix engineer who has moved my entire workflow to the iPad Pro, Pro-Q 4 is an absolute game-changer. The new Instance List allows me to manage my entire session without constant menu-diving, and the sound quality is indistinguishable from the desktop version. It is simply the most surgical and musical EQ available on mobile today."

Marcus T., Senior Mix Engineer

"I am obsessed with the new EQ Sketch feature! It feels so natural to draw the curve I want with my Apple Pencil during a creative session. The 'Warm' character mode adds that perfect analog grit to my vocals that I used to need hardware for. It has completely transformed the way I produce music on the go."

Sarah Jenkins, Independent Producer & Songwriter
