What it does
Several decisions stay in flight at once so each answer can arrive near its scheduled note. A recorded performance can be replayed without live calls.

How you can use it
You can study this project to see how an app plans fast actions ahead of time. In this demo, an automated keyboard plays a set piano piece. Instead of waiting for a live decision right when a note plays, the software asks where fingers should go half a second early.
This advance planning keeps timing steady even when online responses lag. A developer can run the saved performance locally without any special setup. To test live decision-making rather than replaying the recorded run, your developer will need an access key from a TypeSafe account.
