Hello Antonio,

You can build circuits either with Wire, or by hand. Wire helps you keep 
track of the connections.

Once you have a circuit with the envelope player then you can queue() 
parts of the envelope whenever you want.

You can create random envelope. A description of envelope usage is here:

An even easier way might be to use a LinearLag unit.
You can set() the time value to control how fast you want it to change.

Then set the input port to the target value. The output will slowly 
change to match the input.

http://www.softsynth.com/jsyn/docs/autodocs/com/softsynth/jsyn/LinearLag.html

Something like the following:

LinearLag lag = new LinearLag();
lag.output.connect( whatever.input );
lag.start();

double duration = Math.random() * 5.0;
lag.time.set( duration );

double target = Math.random();
lag.input.set( target );


Thank you,
Phil Burk
