      get started. If it hasn't opened automatically, open the preferences by
      selecting <SPAN

CLASS="guimenuitem"

>The <SPAN

      default. It allows you to change settings related to audio output.
      Following explanation of parameters should you give a better understanding on what to choose.</P

>The output device you wish to use. This usually lists JACK
            (if enabled), ALSA and OSS output drivers available on your
            system. All of these drivers require exclusive access to the
            soundcard for performance reasons, so make sure you have no other
            sound applications active in the background. I recommend ALSA to be tried first, then JACK, then OSS.</P

>Samplerate</SPAN
></DT
><DD
><P
>The samplerate at which to render audio in Hz (impulses per
            second). 44100Hz is usually a good setting (CD Quality). The
            higher your samplerate is, the more performance Aldrin consumes to
            render sound. With a lower samplerate, Aldrin consumes less CPU
            time, but the sound quality is degraded.</P

><DT
><SPAN
CLASS="guilabel"
>Latency</SPAN
></DT
><DD
><P
>The time between the rendering of a signal and the actual
            output on the soundcard. Latency controls the size of the internal
            audio buffer that data is being rendered into before it is sent to
            the soundcard. A low latency value will give you a better response
            time, while a higher latency value gives you better
            performance. A value of 5-10ms should be acceptable.</P

      harddrive, you should at least add one sample repository. Click on
      <SPAN

><P
>If you want to download samples online from within Aldrin, you need
	  to supply your freesound credentials. If you don't have a freesound account
	  yet, visit the website and get yourself one.</P

      <SPAN

      tabs. They allow you to select MIDI input/output devices and configure MIDI controller bindings.</P

>Aldrin allows you to use your keyboard like a 2-octave piano.
      Depending which keymap you use, you need to select a proper keymap on
      the <SPAN
