Pitchbend issues

Pitchbend issues

[Jeff Ballard]

Hello,

I am writing a small application to playback standard midi files.  At 
this point, my program seems just about complete.  The only issue I am 
having is that pitchbends are not being played.  I have confirmed that 
the event has the correct channel and parameter value and is using an 
algorithm nearly identical to other implementations I have run across.  
The only evidence I have found is that if I artifically increase the 
bend ammount (10 times the calculated value), I can hear studdering in 
playback on that channel when the pitchbends should take place.  It 
sounds almost like the bend is occuring, but ending so quickly that it 
is difficult to hear.  Does anyone have any idea what might be happening?

Thanks
-Jeff

When you play a file containg a pitch bend event to an aseqdump port with both
aplaymidi and your app, what are the differences in the output?
