<p>
  The visible note range in a MIDI track can be controlled in two
  principle ways: the note scroomer, or the scroll wheel of your
  mouse. 
<p>

  <h2 id="controlling-note-range-defaults">Setting the defaults</h2>

<p>
  The default note range shown in new MIDI tracks is controllable in
  <kbd class="menu">Edit &gt; Preferences &gt; MIDI</kbd>

<h2 id="controlling-note-range-using-the-mouse">Using the scroomer</h2>

<p>
  The scroomer offers two kinds of control.
</p>

<h3>Shift the note range</h3>
  <p>
  "Grab" the scroomer in the middle and move it up or down - this adjusts the
  absolute note range displayed up or down.
  </p>
<h3>Expand or shrink the note range</h3>
<p>
  "Grab" the top or bottom handle of the scroomer, and move that up or
  down - this adjusts the extent of the note range displayed.
</p>

<h2 id="controlling-note-range-using-scroll">Using your scroll wheel</h2>

<p>
  While in internal edit mode (used for editing MIDI), several scroll operations can be used to control the visible note
  range:
  <li>With <em>no notes selected</em>, unmodified
    scrolling will move the visible range up and down.</li>
  <li><kbd class="mod1">scroll</kbd> will increase and decrease the
    visible range (zoom out and in)</li>
  <li><kbd class="mod13">scroll</kbd> will expand either the top or
    bottom of the visible note range (depending on scroll
    direction). Think of this as "show me higher pitches" or "show me
    lower pitches".
