Key Send Delays
Key send delays affect the way and speed that MEAP sends key commands and various other operations to your audio application.
Normal Waits
The default setting. Should work fine on most systems.
Fast Waits
Can improve export speed and should work fine on faster systems.
Safe Waits
For use with slower systems where, for example, graphics redraws are slow.
Also If you experience any odd key presses or anomalies try the Safe Waits setting. This should not be required but may help if trying to track down a potential problem.
