How do I play the note if I know its duration

How do I play the note if I know its duration? Not NOTE_ON, NOTE_OFF

One way is obviously to try to delay the NOTE_OFF by an amount of time. If you look at a MIDI file, you'll see that each note is made up of two events, at different times.

Another way is to send in the NOTE_OFF immediately after the NOTE_ON, but with a timestamp for the time that you want it to end. However, I couldn't get this working myself.

Hi,
i'm trying your second solution but notes don't seem to stop.

msg.setMessage(ShortMessage.NOTE_OFF, 0, midiValue, 127)
receiver.send(msg, (System.currentTimeMillis() + durationInMillis).toLong())

We need to send the timestamp, not the duration right ? Is it in milli seconds ?
I don't know what i'm missing.

Thanks for you reply
