#
#    Notes:
#
#    Of the four Versions of OurMusic, 1 and 2 are similar, as are 3
#    and 4. The only significant difference is the control mechanism;
#    2 and 4 are played solely on ASCII keyboard(s) (multiple  keyboards;
#    the native and additional USB keyboards can be played simultaneously).
#    Collaborative performance is encouraged. Versions 3/4 are somewhat
#    more involved than 1/2; their textures are richer and they offer
#    enhanced options.
#
#    Versions 1 and 3 require a USB MIDI controller with 8+ knobs
#    and/or sliders. The 8 knobs/sliders must have *contiguous* controller
#    #'s, or all be continuous controller 7 on channels 1-8(11). Please note
#    with respect to the latter arrangement: in MyMusicMIDI, pan (if actively
#    controlled) is on channel 9; in OurMusicMIDI, *harmonics* are assigned
#    channel 9; pan, channel 10; and depth, channel 11 (these assignments are
#    fixed). When "MIDI notes" is selected to control harmonics with this
#    option, the "harmonics channel" is thus actually #9. 
#
#    Important: The controller 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 (but not those requiring more than 9 sliders). Choose
#    Scene 4 on the Korg, and Channel "0" in the performance window.
#
#    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.
#
