Shamus Hammons 7a4c28bd86 Rearrangement and cleanup of Part I.
This includes rewriting out all of the "you" language that was peppered
throughout, fixing inconsistencies in layout, and removing <br>s
wherever they were misused and unnecessary (which was quite a lot).

<p>A typical <dfn>MIDI track header</dfn> looks like this:</p>
<img src="/images/typical-midi-track-controls.png" alt="midi track controls"
/>
<p>
To see the full set of MIDI track controls, you need to increase the
<a href="@@track-height">track height</a>
beyond the default. MIDI tracks show only a few of the control elements
when there is insufficient vertical space.
</p>
<p>
A MIDI track has the same basic
<a href="@@audio-track-controls">controls as an audio track</a>,
with the addition of two extra elements. The set of buttons below the main track
controls the <dfn>MIDI channel</dfn>(s) that will be visible in the editor. A MIDI track's
data may span any number of the 16 available MIDI channels, and sometimes it is
useful to view only a subset of those channels; different instruments may,
for example, be put on different channels. Clicking on a channel number toggles
its visibility.
</p>
<p>
To the right of the MIDI track controls is a representation of a piano keyboard
called the <dfn>scroomer</dfn>. This performs a couple of functions.
The scrollbar controls the range of pitches that are visible on the
track, as visualized by the piano keyboard.<br>
Drag the body of the scrollbar up and down to display higher or lower
pitches.<br>
Drag the scrollbar handles to zooms in and out and increase and decrease the
range of visible pitches.<br>
clicking on the piano plays the corresponding MIDI note for reference.
