Use the MIDI Console to view information about timestamp generation
If you want to see the MIDI clock we’re using for timestamps and message scheduling, you can use the time command. It will display the current timestamp in ticks, and the number of ticks per second (the resolution)
Windows MIDI Services is an open source project with all source available on GitHub. We have a great community on Discord as well. Between GitHub and Discord, you should find the information you are looking for.
