About Latency
Latency is loosely defined as the amount of time it takes for a sound made in Session to
reach your speakers. For example, with a high latency (Buffer Size) setting, there will be
a noticeable delay between the press of a key on KeyStudio 25, and the resultant sound.
Smaller Buffer Size settings result in lower latency, but may not function well with slower
systems. If you hear clicks and pops, the Buffer Size setting is too low. To adjust this
setting of Session, open the Audio Hardware dialog (Options > Audio Hardware), select
the desired buffer size from the Buffer Size selector, and then click the OK button.
➜ NOTE: Deselecting the “Low-Latency Streaming” checkbox may also reduce
any clicks and pops in Session audio. This setting is only available if WDM is
selected as the driver type.
Upgrading your Sound Card
If you find that your sound card is incapable of producing acceptable latency times, we
recommend that you upgrade your sound card. Visit www.m-audio.com for a selection
of low latency ASIO audio interfaces for every purpose.
