Hi everybody and sorry for posting this to both, lad and alsa-dev,
i was not sure which one fits better.

Concerning the issue with non-functional midi in on the DSP2000 c-port:
Someone on lau(Clemens?) said the problem is a lack of information an 
how to enable some interrupts.
Matthew Skinner contacted me a couple of days ago (actualy replying to a 
thread on lau, i think), offereing to provide the missing info + 
additional help.

Anyone interested and able to do the required changes should contact 
him: matt at sound-music.com

the original "dialog" is attached below. I'm sorry, it is a little 
cluttered by my mail client :-) hope you can read it anyway.

Kind Regards,

I dont know the best mailinglist to post to or I probably would do so. I can
provide the missing information and some more help.

If you want to find someone with the time, knowledge and passion to write
the extra code for linux then get them to contact myself.
