I'm using a hand compiled kernel under debian testing - 2.6.26.8 with

work. (May have been my mistake but I ended up with a problem with
repeating keys and also the jack daemon wouldn't start properly.)
Will try what you've suggested and let you know how it goes.
Many thanks for the time you've spent looking into this.
cheers,

- using a program which turns the computer
keyboard into a virtual midi
device. This makes the sound much more immediate. Having tried this, the
contrast makes it obvious that there is still a problem with delays from
the edirol keyboard.

Watch /proc/interrupts while trying to play, and see what counters
increment in the matrix. Here's a fun way ... run this in a terminal
window while playing keys on the MIDI keyboard ...
watch -d --interval=0.1 cat /proc/interrupts
What is the kernel version? You mentioned Debian Testing and Ubuntu
Jaunty.
