MidiSequenceTrack describes one track of a MidiSequence. Get them from the sequence’s Tracks collection.
| Property | Description |
|---|---|
TrackIndex |
The track’s index in the sequence |
Name |
The track name, if the file has one |
InstrumentName |
The instrument name, if the file has one |
SuggestedDeviceName |
The port the track was written for, if the file names one |
UsedChannelMask |
Which channels the track uses, one bit per channel. Bit zero is channel one. A track doesn’t have to use only one channel |
NoteCount |
How many notes are on this track, each with its start and end paired up |
EventCount |
How many events are on this track |
LastTick |
The tick of the last event on this track |
A file meant for several instruments at once has a SuggestedDeviceName on each track, so start there when you decide where a track should go. Use it to build a default MidiSequenceTrackRouting, but let the person using your app change it.
Don’t assume one channel per track. UsedChannelMask exists because plenty of real files put several channels on a single track, and a format 0 file puts all sixteen on one.
