[proaudio] patching specimen

[Dubphil <dubphil@xxxxxxx>]

Hello all,

would it be possible to add another patch to the specimen ebuild ?
it would just to exchange a string with another in a file of the sources 
in order
to be able to load multiple instance of specimen and having the jack 
client named with an increment.
I could probably do it myself, but there is something I must learn 
before; is how to create a patch file.

Tell me what you think.

Regards

Philippe
