What Are Expression Controls
Expression Controls are parameters you can automate over time to add nuance and realism, allowing you to "paint" where an effect should be active.
Available Controls
Vibrato
Vibrato is a subtle and rapid fluctuation in a note's pitch, which adds warmth, expression, and richness to the sound.
Split-tones
Split-tones are an advanced technique that creates a rough, textured sound by producing multiple pitches simultaneously. It's perfect for adding a raw, edgy character or a sense of tension to your melody.
Editing Expression Controls
Select the Expression Control below the piano roll.
Click and drag to "paint" the regions to activate.
Simply right-click and drag over an active region to erase it.
