Ableton/Live/UG/10 Editing MIDI/05 Editing MIDI Notes/13 Editing Probabilities
- Probability is the chance a note plays on each pass. The Chance Editor lane is hidden by default; show it from the Lane Selector menu.
- Drag a note's marker between 0 and 100%; the value shows in the lane and Status Bar, as a range when selected notes differ. Or type a value and press
Enter; up and down change it by 10%, with Shift for fine steps. - Notes under 100% show a small triangle at the top left when key tracks are tall enough.
- Randomization Amount in the Clip Content Toolbar randomizes probability around each note's value, for example 50% with 25% gives 25 to 75%. It applies at once to selected notes, or to all notes after
Enter or Randomize. 10.5.13.1 Probability Groups
- A group of notes shares one probability: Play All plays them all or none; Play One plays one of them at random.
- Select notes and press Play All or Play One in the Clip Content Toolbar, or use the Group Notes commands in the context or Edit menu.
Cmd+G (Mac) / Ctrl+G (Win) makes a group of the last type used. - A group has one marker: a diamond for Play All, a triangle for Play One. Right-click it, or use the buttons, to change the type.
- Hovering a grouped note highlights the group, and the Status Bar shows the type. Grouped notes always show the triangle, even at 100%.
- Ungroup,
Cmd+Shift+G (Mac) / Ctrl+Shift+G (Win), or Ungroup Notes removes notes from a group; adding a note to another group moves it.
