Double-click the icon to open the ProKeys Sono Control Panel:
Latency
Latency is defined as the time it takes for audio to pass through your computer and appear at the outputs of ProKeys Sono . This
parameter also adjusts the amount of latency when using “virtual instrument” software on your computer . Please see your virtual
instrument software’s documentation to learn more about this .
Smaller buffer sizes result in lower latency, but may not function well with slower computer systems . The Latency slider selects the
buffer size that ProKeys Sono uses to handle digital audio streaming . If you notice significant latency when using ProKeys Sono,
you can experiment with lower settings . If you experience stuttering or crackling in your audio playback, try using a higher latency
setting .
Use the slider to adjust the buffer size to the lowest possible setting that still provides error free recording and playback .
To find your system’s optimum buffer size setting, begin with a high setting and gradually reduce the size until you begin to hear
clicks, pops, or other audible glitches in your audio . Then, raise the buffer size setting until these glitches disappear . You may need
to stop playing audio any time you change this setting and certain applications will require you to re-launch the program before the
new buffer size settings become active .
