A timepoint is a point in musical time.

When you’re using tempo-relative timing in Max, the timepoint object will automatically report when a specific moment in musical time has been reached by the transport.

many timepoints stored in a coll

You can use as many timepoint objects as you’d like. This example, however, shows a way that you can save many timepoints in a coll object, use the output of the coll to set a timepoint, and use the output of the timepoint object to signal when that timepoint has been reached and also to read the next timepoint from the coll and set up the timepoint object itself for the next timepoint it should report.
