Setting the Length of the Waveform

The overall length of the waveform (sound) is determined by a parameter in the Output operator. To set the length of the waveform (that is, the length of time in seconds the patch will play):

  Open the simple patch you created in the 1st tutorial, Creating a Simple JSYD Patch :

• Select the Output operator by clicking on it once. The output operator is on the right side of the window and resembles a speaker.

• When you have the Output operator selected, you should see these parameters at the bottom of the window:
   

      

  Note the value in the Duration field. This value sets the duration of the sound (waveform) in seconds.  Setting the duration to 4 would produce a 4 second sound.  Setting the duration to 2.5 would produce a sound of 2.5 seconds.

In addition to setting the duration of the waveform, you should also get in the habit of selection the RADIO BUTTON, Output to Memory instead of the default Output to WAV file. So, after you set the duration and select Output to Memory, the Output operator should look like this:

Synthesize the sound and listen for the overall length.

Try changing the duration of the output to different values and then listen for the results. You have to SYNTHESE the patch after EACH parameter change. Otherwise you will not affect any difference in the sound you hear.
