Start and End Note

Example script (scamp): examples/Tutorial/16_start_and_end_note.py

Download: 16_start_and_end_note.py

Plays notes by calling start_note (or start_chord) and then manipulating them afterward, instead of defining the course of the note from the beginning with “play_note”. The “start_note” and “start_chord” functions return handles that can be used to change the pitch, volume or other parameters of the note after they have started, as well as end the note.
