Manual Adjustment of Stem Orientation
You can manually change the stem direction of notes in Crescendo by selecting the note(s), right-clicking, and choosing "Stem > Up/Down"
. This allows you to set stems up or down as desired for individual notes or groups of notes.
Default Setting for Stem Orientation
Crescendo automatically determines stem direction based on standard music notation rules (typically, notes above the middle line have stems down, and notes below have stems up)
. There is currently no documented option in Crescendo to globally change the default so that all stems (and thus beams) always point up by default for all new notes
. Each note or group must be manually adjusted if you want a non-standard default.
Beam Orientation
Beam orientation follows the stem direction of the notes it connects. By manually setting all stems up, the beams will also orient upwards accordingly
Summary Table
Feature Can Default Be Changed? Manual Adjustment Available? Stem Orientation No Yes (per note/group)
Beam Orientation No (follows stems) Yes (by changing stems)
Conclusion
You cannot change the global default setting for stem or beam orientation in Crescendo to always be up. However, you can manually select notes and set their stems (and thus beams) up as needed.
