Latency

In order to reduce latency (the time between pressing the key and hearing the sound), it’s best to keep your hardware buffer size as low as possible.

If you’re using sounds that require a lot of memory or CPU power (such as some of the acoustic pianos), you might need to find a balance between optimizing for live use and increasing the buffer size to avoid glitches.

NOTE: In some programs, such as MainStage, the total resulting latency is a combination of I/O Buffer Size and the program’s Driver Latency Settings.
