One of the main claims of JACK MIDI is sample accurate synchronisation with the
audio. This is not terribly relevant when generating tracks playing live, but
becomes more significant where automation is used, or where control is being
bounced around several apps/plugins.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

   I just pushed a fix [r15764] for a rather serious pitchbend bug.  At 
playback from the middle of a segment, a pitchbend of 0 (-8192) would be 
sent out on every channel.  This would shift the pithces downward 
depending on the instrument's response to pitchbend.




Confirmed...

   If you've been running from svn, please update to the latest so that 
you do not run into this bug.


Unfortunately it seems now the bug seems to still be there, but sending 
out a pitchbend of 8192 - this is in r15766

  I suspect that pitchbend isn't reset by the usual resets.  Reason I 
know this is that it wasn't while I was testing.  Also rg's panic button 
doesn't zero pitchbend either.  Of course, each synth probably does 
whatever it wants.  So, yeah, probably safe in most cases.

   That is working as designed.  8192 is the correct number (in the 
0-16383 system).  That means no pitchbend at all.  So, from a fresh 
power-on of your synths, if you stop and play in the middle of a 
segment, it shouldn't suddenly end up pitched down.

Sorry for the noise.

Lorenzo.



   If you don't want pitchbend going out ever, remove pitchbend from the 
device's controllers.  If it's still going out after this, let me know 
and I will add it to my todo to track down.  I have another pitchbend 
ruler issue to track down, so I can take a look at both of them while 
I'm in there.
