[Ardour-Users] LinuxVST in Ardour4.0.0 on Ubuntu 14.04 LTS x86-64?

[Gunter Königsmann]

I am currently working with wxMaxima which is a front-end for the 
computer algebra system maxima and I always wonder why it is 
implemented as a client-server architecture: The actual mathematics is 
done by a separate program. This sounds monstrous and has its 
disadvantages, too. But if the process that does mathematics crashes 
this does not tend to be a problem: The program that contains the 
worksheet with the actual user data still lives on.
Would it be possible to write a external program that scans for AU or 
VST plug-ins and populates a list with them? This program could run in 
the background not delaying the start-up of ardour too much and it 
could even inform the list that a certain plug-in crashed before 
actually testing if this assumption was right and (if it didn't) 
correcting the error after actually scanning the plug-in: This way the 
list would even contain the information which plugin caused a crash.

Kind regards,

    Gunter.
