I do get the No Region defined message quite often when I hit a key 
that... has not region defined. :) However, I haven't seen a segfault 
coralated with this.

The malformed midi message was created by code similar to the following
ev1->data.note.channel=ev2->data.control.value
where ev1 is a noteon event and ev2 is a controller (sustain pedal) 
event. So I think that the channel value might be out of bounds. This 
code is pretty nonsensical and was written in error. However it did 
cause ls to segfault.

Vlad, I have never tried to gdb over irc. I would be happy to learn how 
this is done if you think it would help. I'm pretty sharp with gdb and 
might just be able to get you the info you need myself (although I 
haven't familiarized myself with the ls code at all). Also, I could just 
make you a temporary account on my box and you could gdb through ssh.

I tried the lastest cvs ls and have not seen a disk stream error yet 
with > 2 channels. Right on!

Also, in regards to running ls as root... I just realized this morning 
that the voice dropping I had mentioned to the list last week was caused 
because I had not chmod +s linuxsampler .
When I do not run ls as root on my system I get lots of audio artifacts 
and lots of voice dropping.
