[Alsa-user] Quattro MIDI trouble SOLVED! And, another question...

[Daniel Hawthorn]

I seem to have come to the bottom of this one in some further 
experimentation.  I've gotten the midi input on my quattro to work 
(very) occationally, without understanding why.  Each time I got it to 
work I would reboot to see if whatever I thought it was, was in fact the 
real solution.  Each time though it just went back to not working on a 
reboot.

So... I finally figured it out.  The key was that I had to reconnect the 
quattro _with no midi activity_.  Each time I tried before, it was 
connected to my Roland keyboard which was continually sending out it's 
active sense midi data.  If I disconnect the midi cable (or shut off the 
board) I get midi input working fine after I reconnect the quattro to 
the usb bus and reconnect my midi cables.

Now, I had heard this was a problem with the midisports, but never with 
the Quattro, since there was no firmware transfer or anything.  I had 
never had this problem with my old RedHat system.

So, now I just have to make sure I keep my midi controller powered off 
while booting up my system.

First off, thanks for the help on this so far.  Secondly, why could this 
be happening?  Any ideas?

Thanks,

Daniel
