#
#    Notes:
#
#    Both "Brother Sun Music" and "Sister Moon Music" require one or more
#    MIDI controllers with 8-9 knobs (the 9th controller is only used
#    with the Pan option). The 8 knobs/sliders must have *contiguous*
#    controller #'s, or all be continuous controller 7 on channels 1-8(9).
#    Also, all MIDI devices must be sending on the same channel. (On
#    multiple devices, the various controller #'s may be distributed
#    among the devices in many different ways.)
#
#    The first 7 controllers in "Sister Moon" vary volume for the 7 tones
#    (or tone pairs), while #8 is a MASTER volume control. The same is true
#    for "Brother Sun" except that there are only 6 tones; controller 7
#    varies overall pitch slightly. 
#
#    Important: The MIDI controller(s) must be attached AFTER boot, and
#    BEFORE the version is selected. It is assumed that the controller is
#    a USB device. The inexpensive Korg nanoKontrol is one appropriate
#    controller choice; it can nicely handle either 8- or 9-slider
#    renditions. Choose Scene 4 on the Korg, and Channel "0" in the
#    performance window. Preset all controllers to zero prior to start;
#    then, when using Pan, change controller 9 to its opening position
#    following start.
#
#    If you get audio glitching, open Sugar's Control Panel, and turn off
#    Extreme power management (under Power) or Wireless radio (under
#    Network). Stereo headphones (an inexpensive set will work fine) or
#    external amplifier/speaker system are highly recommended. The audio
#    level will sound higher for "Brother Sun" than for "Sister Moon."
