JSYD Tutorial 1
a Simple JSYD Patch
To create a simple JSYD Patch:
The JSYD window consists of a palette of OPERATORS arranged
across the top and an OUTPUT operator located on the right side
of the window. Also, there is an area on the bottom of the window which
will display either a graphic representation of the waveform
of the patch, or a specific operator's various input and output parameters.
More on this later.
To create a simple JSYD PATCH:
Your window should look something like this:
To see the input/output parameters of the OSCILLATOR
operator, just select it by clicking on it once.
You could SYNTHESIZE
the patch now but the volume of the output would be VERY LOUD.
It would be best to set the output volume of the OSCILLATOR
operator to a more conservative AMPLITUDE.
- Select the OSCILLATOR
operator by clicking it once. You should see the output
parameters of the OSCILLATOR
in the area at the bottom of the window and it should look like this:
In future examples, only the parameter area of the window will be
shown in order to conserve space:
Change the value in the AMPLITUDE
field to .5 (that's "point" 5 (5/10ths), NOT 5.
Other parameters may not be visible until you resize the parameter
field of the window. Click and drag on the DOT with is located in
the center of the window just above the parameter filed. Drag it UP
to reveal other parameter fields:
should remain at 440.
Note the default wave type is SINE.
Click OK to close the edit window.
After the window closes, click on the SYNTHESIZE
button at the TOP left of the window (it has a green "S"
on it). This causes JSYD to COMPILE
the file and store a digital representation either in MEMORY or write
it directly to a file. More on this later.
- Make sure your headphones are plugged in and the volume of the
Macintosh computer is adjusted properly.
- Click the PLAY button at the TOP left of the window. .
If you set all the parameters correctly you should hear a SINE wave
at amplitude .5 for 2 seconds.
- Compare what you hear from the JSYD patch to the sound you should
hear when you click the link below:

You can save your patch by choosing "Save As" in the File
popup menu in the top left corner of the JSYD window. Save your file
in the USERS folder of the computer hard drive. You may not have access
privileges to save files in other areas of the computer.
