   <glossdef>
     <para>
	  Definition of time and level values to shape a
	  signal. Most common structure is a so called
	  ADSR-follower. Such an envelope has a rising
	  Attack-time, a first falling Decay time leading
	  to the Sustain level. At the end of the cycle
	  there's a Release time, damping the signal's
	  strength. For example a piano has a rather
	  short Attack time, no Sustain level and
	  a Release time. Strings have varying Attack
	  times as well as varying Decay, they have a
	  Sustain level and very flexible Release time.

	  Voltage Controlled Amplifier, an amplifier whose amplification
	  depends on a controlling voltage. Instead of making it louder
	  by turning a knob you raise the controlling voltage. Often
	  used in conjunction with Envelopes or LFOs to shape a signal.

	  Instead of changing the frequency by turning a knob you raise the
