Hello.
The already mentioned page
http://www.mathworks.com/access/helpdesk/help/toolbox/simulink/rn/simulink1…
says that Mathworks disabled the realtime control from Simulink.
That is, it looks like one cannot build a realtime synth
with Simulink. Could anyone confirm how the controls worked
earlier and now?
Has anyone found prior art for music software? I'm sure J.O. Smith's
writing in CMJ does not help "as is". And even then, the Labview/Reaktor
style front panel building prior art must be found. Some other
GUI system won't help.
While I don't know exact details of the patent, I think I have
found a way to circumvent the patent. I tried to contact Mathworks
but they don't have a contact method for non-customers. They would
have expertise and interest to examine what I have found.

I read it as:
- You cannot have realtime-control from a GUI, but it is OK to alter the
value and let the change take effect when the window (with the
controller) is closed.
I haven't used the product (!), but it is my understanding that
Mathworks used to change its internals when you hit 'enter'. Now it
happens when you close the window.

Music software is not affected at all by the patent. A very central part
of the patent is the purpose of the program. Their business idea, so to
say.

I have one too :)
Use a cheepish midi controller with sliders and buttons, and you are
done with the claims regarding GUI. As an added bonus, users will not
get 'mouse-arm' from extended use.
Another weak point in the patent is the detail where they mention
windows (as in X or some such.) There is a competing product doing
everything on a single screen. They even disable the taskbar to make it
very clear that they differ from the patent on this point.
