<h1>About the Groove Scribe - original text:</h1>

The Groove Scribe was built to help drummers create, practice and share grooves.
<ul>
  <li>
    A simple interface allows easy groove creation that automatically creates
    printable sheet music for printing and sharing.
  </li>
  <li>
    Midi playback with tempo and a metronome makes it easy to hear and practice
    difficult grooves.
  </li>
  <li>
    Sharing is simple with a URL and the recipient can view the groove in any
    web browser.
  </li>
</ul>

<p>
  <b>How it works:</b>
</p>

<p>
  The Groove Scribe is written in HTML and Javascript and runs entirely in the
  browser.
  <a href="http://abcnotation.com/">ABC Notation</a> is used to create the
  printable sheet music. When notes are changed on the screen, new ABC Notation
  is generated which creates the sheet music. To play the music, Groove Scribe
  generates a <a href="http://en.wikipedia.org/wiki/MIDI">MIDI</a> file and
  plays it using the browser audio interface. The soundfont used by the midi
  player uses custom drum samples from
  <a href="http://mikeslessons.com/">Mike Johnston's</a> kits.
</p>

<p>
  All of the icons and images used by and created by the Groove Scribe are SVG
  or fonts so the interface scales to any resolution with no scaling artifacts.
  Try zooming in on the page to check it out.
</p>

<p>
  <b>How it swings:</b>
</p>

<p>
  The swing slider controls the amount of "swing" that is added to the playback.
  It does not effect the printable sheet music. To generate swing, a delay is
  added to the upbeat notes in the measure. The upbeat notes are the "a" and the
  "e" in a 16th note groove. (1e&a), and are the "&" notes in a 8th note groove.
  (1&2&3&4&). During MIDI generation, the program extends the duration of the
  downbeat notes and shortens the duration of the upbeat notes. The percentage
  of the swing controls the percentage of the note duration that the upbeat is
  delayed. (NewDelay = NormalDelay + (NormalDelay * SwingPercentage)
