The following notes pertain to Using Envelopes in Buzz:

• You must have a sample selected from the Wavetable to build an envelope. If you build an envelope without a sample selected it will disappear as soon as you switch windows.
  
  
• Each Envelope may only have one sustain point (for obvious reasons). This Sustain point is not required.
  
  
• The Visual Envelope Editor spans the length of the current sample. Therefore the distance between any two points will vary from song to song.
  
  
• You may not delete the first and last points of an envelope.
  
  
• Each envelope is related to a sample and one individual machine. This means that you may have many envelopes for each sample, all tied to separate machines.
  
  
• Envelopes may have as many points as you wish.
