// This is a test of pre-roll, post-roll and periodic features on sound-objects
// It's meant to explain what it is about rather than demonstrate musical utility!
// 1) PRE-ROLL, POST-ROLL
// So far, the main practical utility I found is the handling of sound-objects that contain messages sent to a MIDI sampler. Sometimes you need to send a message triggering, modifying or cancelling a sound at a date which does not fall into the time-span interval of the object.
// There is a theoretical motivation too: there is no reason to force the time-span interval (which is used to determine the sound-object's physical duration) to be bounded exactly by the first and last events (MIDI messages).
// Set your synth to a piano and play the following sequence
// You will notice that the grace notes aren't taken into account in the timings
