<A NAME="setTempoFactor(float)"><!-- --></A><H3>
setTempoFactor</H3>
<PRE>
public void <B>setTempoFactor</B>(float&nbsp;factor)</PRE>
<DL>
<DD>Scales the sequencer's actual playback tempo by the factor provided.
 The default is 1.0.  A value of 1.0 represents the natural rate (the
 tempo specified in the sequence), 2.0 means twice as fast, etc.
 The tempo factor does not affect the values returned by 
 <code><A HREF="../../../javax/sound/midi/Sequencer.html#getTempoInMPQ()"><CODE>getTempoInMPQ()</CODE></A></code> and <code><A HREF="../../../javax/sound/midi/Sequencer.html#getTempoInBPM()"><CODE>getTempoInBPM()</CODE></A></code>.
 Those values indicate the tempo prior to scaling.
 <p>
 Note that the tempo factor cannot be adjusted when external 
 synchronization is used.  In that situation, 
 <code>setTempoFactor</code> always sets the tempo factor to 1.0.<DD><DL>
