# Set sched ahead time globally

``

    set_sched_ahead_time!  time (number)

Specify how many seconds ahead of time the synths should be triggered. This represents the amount of time between pressing ‘Run’ and hearing audio. A larger time gives the system more room to work with and can reduce performance issues in playing fast sections on slower platforms. However, a larger time also increases latency between modifying code and hearing the result whilst live coding.

Introduced in v2.0

## Example

# Example 1
``
    set_sched_ahead_time! 1
| ``
    # Code will now run approximately 1 second ahead of audio.
