linuxsampler

[Doug Regehr]

How do I install linuxsampler on UbuntuStudio 12.04 amd64?  When I do 
"sudo apt-get install linuxsampler" I get this response:

Package linuxsampler is not available, but is referred to by another 
package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Strangely, I can install qsampler just fine...but of course it doesn't 
run without linuxsampler.  What is the recommended way to get 
linuxsampler?  Compile it from source?  Install it from a PPA?
