When the KeyStudio 49i audio drivers are installed, the Control Panel software is also installed onto your computer system  The 
Control Panel gives you access to certain audio hardware parameters and status readouts  

The M-Audio KeyStudio 49i Control Panel icon appears on the task bar (located close to the “clock”), and is also accessible from 
the Windows Control Panel  Double click the M-Audio Control Panel icon to open it 

The following screenshot shows the KeyStudio 49i Control Panel in Windows XP  

The Latency Page in the Windows XP and Windows Vista control panel enables you to adjust the unit’s buffer size in order to 
achieve optimal balance between system stability and audio latency 

Latency is defined as the time it takes for your MIDI input (when using software synthesizers) or audio input signals to appear as 
audio at your computer’s outputs   

Smaller buffer sizes result in lower latency, but may not function well with slower computer systems  The Latency slider selects the 
buffer size that KeyStudio 49i uses to handle digital audio streaming  If you notice significant latency when using KeyStudio 49i, you 
can experiment with lower settings  If you experience stuttering or crackling in your audio playback, try using a higher latency setting
