The envelope lets you change how the sounds from your Synth Kit begin and end. The beginning of
a sound is called the attack, and the end is called decay. The attack and decay can be very sudden or
very gradual. Changing these values will let you create many different sounds with your Synth Kit.

An Envelope of Sound.
Set your keyboard's key mode to hold. This will make exploration of the envelope module easier.
Start with both envelope knobs turned all the way down (left/counterclockwise) and then turn the
decay knob up just a bit. Playing the keyboard should produce short, staccato tones. That's because
the sounds are beginning and ending suddenly. Now take some time to explore the different sounds
you can create by changing the envelope module's controls.
Can you create sounds like these instruments?
