MusicSequence and velocities for note off events

Hello All,

Is it possible to obtain velocities of original note off events from a music sequence?

I use the MusicSequenceFileLoad function for parsing a MIDI file. So, I get a note on and the corresponding note off events as a single MIDINoteMessage object. It contains the releaseVelocity field which I expected should contain velocity of the original note off event. Unfortunately, I always get 0 from this field. Using the same velocity for note on and note off events seems not correct. I clearly can hear that some notes are fading away earlier than should be in this case... I tried to use the maximum 127 velocity for all note off events. Also, I tried to use note on events with 0 velocity instead of note off events. But rendering with the DLS music device produced even more incorrect output in both cases.

I need to have separate note on and note off events to be able to send them to the DLS music device with the MusicDeviceMIDIEvent function. I can't use MusicPlayer since it is still broken on Mac OS X 10.7.3. And I'd like to keep parsing with a single MusicSequenceFileLoad invocation because of simplicity and less amount of code...

Best regards,
Igor
