Editing workflows

3 prompts

Quantize with feel

Select notes > press Q > choose 1/8 swing at 55% strength to tighten while keeping groove.

Velocity layers

Switch to velocity view > draw crescendo > copy to other lanes for cohesive dynamics.

Loop management

Set loop points in the timeline > enable loop playback > edit endings while monitoring transitions.

Keyboard shortcuts

3 prompts

Select intelligently

Ctrl+Shift+Click isolates a lane; Alt+Drag copies notes without affecting timing.

Fast navigation

Hold Space for hand tool, use Page Up/Down to jump octaves, and use +/- to zoom.

Automation editing

Press A to toggle automation lanes, then Shift+Drag to draw precise CC ramps.

Creative ideas

3 prompts

Call and response

Duplicate a melody to a new track, offset by two bars, and invert for instant counterpoint.

Chord texture

Copy chord tones to higher octaves, reduce velocities, and add slow automation for pads.

Percussive swing

Shift every second hi-hat 10 ms late, reduce velocity slightly, and layer ghost notes.

Featured single-line prompts

Clean up timing

Select the clip, press Q, and apply 1/16 quantize at 60% strength for natural tightness.

Shape dynamics

Show velocity view, drag a crescendo across the bar, then copy with Ctrl+D to repeat.

Duplicate arrangement blocks

Use Ctrl+A to select the section, hold Shift, and drag to clone it while keeping automation.
