The envelopeVolumes variable - The Sentinel on the BBC Micro

       Name: envelopeVolumes                                         [Show more]
       Type: Variable
   Category: Sound
    Summary: A table of offsets into the envelope data for bytes that control
             the volume of each envelope, so we can change their volume levels
    Context: See this variable in context in the source code
 References: This variable is used as follows:
             * ProcessVolumeKeys uses envelopeVolumes
