       Name: SFXCR                                                   [Show more]
       Type: Variable
   Category: Sound
    Summary: The voice control register (SID+$4) for each sound effect
    Context: See this variable in context in the source code
 References: This variable is used as follows:
             * NOISE uses SFXCR


 The voice control register is set in this table as follows:

   * Bit 0: 0 = voice off, release cycle
            1 = voice on, attack-decay-sustain cycle

   * Bit 1 set = synchronization enabled

   * Bit 2 set = ring modulation enabled

   * Bit 3 set = disable voice, reset noise generator

   * Bit 4 set = triangle waveform enabled

   * Bit 5 set = saw waveform enabled

   * Bit 6 set = square waveform enabled

   * Bit 7 set = noise waveform enabled
