|
A sound is initialized with a pathname corresponding to an audio file on the disk.
|
Connect a pathname to the first input (<self>) to initialize the instance.
|
If it is unlocked and unconnected, evaluating the box will open a file chooser dialog and allow the selection of a sound file to load.
|
|
The other inputs/outputs correspond to :
|
- <tracknum> = a track number on which the sound will be dispatch at playback. Tracknum can also be changed from the sound editor.
|
- <markers> = a list of markers (time in seconds). The markers can also be added/moved/removed from the sound editor.
|
|
NOTE: These inputs can be connected and will be evaluated even if something is connected to he <self> input of the box.
|
|
Press 'space' to play/stop the sound file.
