Dear Gert,

Thanks for your e-mail. The list of goals is very good. It is
achievable, but there is still work to be done to reach it.

You can find my comments on each issue below

We don't have such a model! It is urgently needed. Who is going to make that?

Not tested yet. This works with the old UVAS, but we don't have the new one yet. Otherwise OK.

The Max-part is under testing, and there are problems. As far as I
know Mattias is working on this and Samuel is helping with testing. I
think Mattias would be the best person to describe the situation in
more detail, if required.

The old UVAS is not capable of these, so to get the testing to proceed
we need the new UVAS, and we should have it on Monday.

Yes

Yes

Yes

It seems that there has been some confusion. I thought that Max will
load the material database, but it seems that I've been mistaken. We
will make a vml-database of acoustic materials and load it to the
Verse server to overcome this problem.

Mattias?

No.

Quel Solaar works in Windows. Linux version hasn't been tested
lately, but at least several months ago we didn't succeed in
compiling it.

True!

The frame is rented from the Fair Center, and they will install and
unistall it for us. The room will be covered by curtains on three
walls (Tapio, please, correct me if I'm wrong)

I think we can make it by e-mail if you have good answers to the open
questions, most importantly a new model is needed.
