Ok. I updated the Jack code and compared the two different system.  
There is a bug in the Jack implementation of this so  I am going to  
give it a look through. This is the bug: when I make a selection and  
click set. I then click loop. It starts out sounding okay but when it  
loops around I here the first and second notes of the loop together  
when I am supposed to be only hearing the first note. This is proceded  
by the second note exactly when it should be. Everynote is there in  
time it is just that I hear two notes when there should be one note.  
The pattern selected was a scale passage. Do you know what is causing  
this. I need to get up to speed on how this looping works. Once I get  
importmidi accepting multiple voices per staff I want write a script  
for mma. Mma is a midi accompanyment generator. A user could define  
chords and then select a style and then the chord list and style will  
be  fed to mma which exports a midi file. The midi file gets imported  
and provides the accompanyment parts fir the chords defined. Then user  
can select a range and they can improvise over it. It could turn  
denemo into kind of a "band in a box".
