The intention is to make the bypass on the compressors work too. At the
moment they are hardcoded because that was the easiest way to get a proof
of concept out the door.

If the compressors are bypassed do you need a seperate application?

We should try to keep the signal flow. leading the eye down the interface
and then back up again to the output controls is bad UI design.

How about a collapsable panel for the multi channel band outputs directly
under the compressor panel so we don't add extra space unless it is
explicitly requested?  We could also make the compressors optional by
hiding the compressor panel.

There nothing specific to jamin online.

Looks like you need this osc-midi bridge:

http://controsc.sourceforge.net/

Dave Phillips has an interesting article here:

http://www.linuxjournal.com/content/introduction-osc

However what we really need is a step by step instruction manual for
jamin. If anyone wants to enlighten us how it is supposed to work that
would be handy.
