Beams and Stems beam groups - AaronDavidNewman/Smoosic GitHub Wiki

By default, notes are auto-beamed so that a 1/4 note is beamed. So 1/8 notes in 4/4 time will be beamed in 2's, 16th notes in 4's etc. In triple time (e.g. 6/8, 9/8), 1/8 notes are beamed in 3's. You can change this default in the Score Preferences.

You can split a beam at any point using the x (mnemonic: x to cancel beaming. You can create a beam by selecting the notes and typing Shift-X. Only notes with 1/8 note duration or less can be beamed.
