FREE · VOCAL MIXING PLUGIN · VST3 / AU

A free vocal mixing plugin: one window, whole chain.

A vocal chain is usually five or six plugins: tune, EQ, compression, saturation, delay, reverb. SCRAMBLE's VOCAL CHAIN mode puts them in one screen with a live pitch graph. Start from a preset, set the key, then tweak low cut, grit, air, width, delay and reverb. The free version has 10 vocal presets; the Bundle adds 90 more plus COMP and SPACE.
