It has a mechanism to reduce it, quite probably adding some latency. But better always 8ms of latency than random jitter between 1ms to 8ms.

This will also help with WiFi + rtpmidi and bluetooth.

From the (oldish) midi.org article[1]:

> The Universal MIDI Packet format adds a Jitter Reduction Timestamp mechanism. A Timestamp can be prepended to any MIDI 1.0 Protocol message or MIDI 2.0 Protocol message for improved timing accuracy.
