Tempo can be changed up or down using the Tempo up and Tempo down behaviours, and specifying the amount by which to change in the dialog box. The tempo can be set to a particular value by using the Tempo set behaviour. The name of the voice to be muted or unmuted is specified in the behaviour dialog box. This allows the volume of an individual voice to be changed. The dialog box allows two different parameters to be changed - 'volume' and 'velocity'.
Volume affects the overall loudness of the voice, and the changes can be heard immediately.
Velocity affects the loudness of notes that commence after the velocity change has been made - it does not affect the loudness of any sounds or notes already playing. Spot effects and riffs Spot sound effects and musical riffs can be triggered in response to any HTML event. Spot effect This behaviour triggers a spot effect to be played on a specified voice. The voice name is specified in the dialog box, along with various properties such the pitch at which the sound is played, its duration and loudness. The sound effect to play can be chosen from a library supplied with the Dreamweaver extension set or a vector can be exported from Koan Pro to the text field.
