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 a graphic representation of the waveform of they patch together
with their various input and output parameters.
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 volume of the
output to a more conservative AMPLITUDE. Do this:
- Double Click on the OSCILLATOR OPERATOR to open its edit
window. It should look like this:
In other examples, only the parameter area of the window will be
shown in order to conserve space:
Change the value in the "Amp" field (Amplitude) 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:
The Frequency 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. 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:
