How does delta time work for different tracks within a midi file?

Timestamps in a MIDI file are delta-times -- you don't encode the time that an event occurs, you encode the time difference between sequential events on that track. If events are evenly spaced in time, their delta times should be the same.

How do I split a track in a MIDI file?

Control-click the MIDI region, then choose MIDI > Separate by MIDI Channel from the shortcut menu. A separate MIDI region is created for every MIDI channel found, containing all matching events. Each region is created on a track with an instrument channel that matches the MIDI channel.

What is MIDI time?

MIDI Time Code uses absolute time in its messages (the actual time on the clock from the beginning of the song or reference point in hours, minutes, seconds, frames, and subframes). This data can then be translated into SMPTE messages (the kind of synchronization data used in film and television).

Do MIDI files contain tempo?

MIDI files normally contain the tempo information for playback at the right speed.

How long is a MIDI tick?

2 Answers. The formula is 60000 / (BPM * PPQ) (milliseconds). Where BPM is the tempo of the track (Beats Per Minute). (i.e. a 120 BPM track would have a MIDI time of (60000 / (120 * 192)) or 2.604 ms for 1 tick.
